This helped me to do this. Home theater AV receiver --> frontal main speakers --> LOC --> stereo amplifier --> One pair of speakers. Now I can use only one pair of main speakers for music and for movies and games. I don't see this solution very often. Thank you.
Couldn't have timed this better. You guys have have saved me a lot of time. Please spare a few minutes for my complicated question but before that; Amazing job done by the presenter explaining all the confusing things in layman term's. Was a Subscriber earlier but I tried subscribing again 😇✌ After countless hours of sleepless nights and hours of research with a tight budget, I wanted to have the best setup which suited my needs. Clear Full Range Music(EQ control) with Accurate BASS. Have bought a 840watt's Blaupunkt 4 channel GTA 470 Digital Sound Processor Amplifier , JBL CSX-1400BP 12" Subwoofer, PAC PDLC 21 Active 2 channel LOC, Surge F8 Flo True 8AWG 800W AMP wiring kit which is on its way. I'm hooking the the 2 channels of the Amp to the front speakers and the 2 bridged channels to the Sub. Since I'm having a DSP Amplifier with various settings such as X-over control, Subsonic control, Phase control, Delay control etc. Does the front speaker signals give full range output i.e If I tap into the front speaker signals with the LOC, will I be able to achieve a full range surround sound system in my car with DSP control function working properly? Was thinking about a 4 channel LOC but thought it would be useless since I'm using only 2 front channels of the amplifier for speaker and remaining 2 for a Sub. I can use the PAC PDLC21 with a low output gain settings since it can pump out 10V unlike a passive LOC and Adjust the gain in the Amplifier to adjust the Fader setting to achieve surround sound from a 2 channel LOC. My stock HU is a 4 speaker outs with a stock 6 speaker(2 tweeters+4 mid speakers) setup. I'm planning to change my Stock front speakers too, Any suggestions for the type (and brand) of front speakers which will suit my setup?
Being that this a factory 4 channel with tweeter, it's likely that you have full range output on all four speakers, we never truly know without testing it. If I were to wager, I think your setup will be fine as described.
Best LOC video I've found, extremely informative. Only one question remains for me: Is there a limit to the length of wire ran on either side of the LOC? Should the speaker level side be short and very close to the head unit, or should the low level side be short with the LOC closer to the amplifier? Is there a medium, or is it not important? I see how yours are setup and I'll mirror that for now. Thank you very much.
Yes what did you run the remote wire to? Most of the fuses in my car are constant Im curious to what fuse turns on when the ignition key is turned on. I have a 2007 cadillac escalade.
Ben Kea the fuse that says ACC but please be mindful those fuses are constant on one side and not constant on the other side. Took ten years installing stereos and replacing dead batteries before CZcams was invented hahaha. Hope this piece of info helps, consider yourself blessed for coming across it. I know I was... Love you guys, Happy New Year 2020
I have the loc pro LP7-2. With this converter you can just connect the remote wire directly to the amp with out having to run a remote wire through your vehicle. It’s all just depends on which converter you have. Hope this helps
I have a 2016 Chevy Silverado. IV installed everything and it works but how do I adjust the radio to maximize quality and bass?. Turn bass up or down? And then turn gain up on amp?. Not much tuning options on factory radio, Thank you for your time
Amazing this is professional engineering technical work, for like this professional work you must pay any amount of labor charges. Excellent explanation.👍👍👍 Question. Car with fiber optic amplifier systems to upgrade sound unit to aftermarket Sony or alpine.. Etc how can used the original amplifier with fiber optic cable, or delete all systems or what the best solution or option I have.
im planning on doing something like this on my 00 323i. My rear deck speakers are blown as of right now and im thinking of just using the wires from that, and putting an loc in my trunk with the rear deck speaker wires running to it. Then running rca to my amp. Do you think it would work?
So, I cut the right front speaker wires from the factory unit.. now I connect the wires to the LOC and then use the other side of the speaker wires and run it to the amp?
In addition to running speaker wires from the LOC to the car speaker wires, I just realized I ran an additional set on both car speakers and ran them into the speaker terminals on the sub amplifier obviously where the sub speaker wires go into. The sub works and sounds great I just don’t know if there’s any issues to having another set of wires on each side of the car speakers running into the speaker terminals on the sub amplifier
Thanks man , I have a question. I tapped in to my factory subwoofer but my PAC LP7-2 won’t play a beat. I’m guessing it doesn’t pick up those frequencies right? Should I upgrade to a LC2-I
Quick question I got the kicker version of this loc which has the remote wire. But my question is, is it OK to tap into the stock OEM subwoofer connection? Is it too much power for that little device or will it be OK? It’s the stock amp and subwoofer plug in the back of the mega cab behind the seats . Just because it’s easy to access is why I’m asking
Why do you wire LOC converter to the wires coming out from the factory amplifier instead of wire in before the factory amplifier? Is there much difference in reality?
Please answer my dumb question? I was using RF-HLC4 LOC and the front left speaker was cutting in and out sometimes on low volume. Then i replaces the loc with PAC LP3-2 prod and the sound is too low. Gain settings in the amplifier is same but the sound is very low. Can the volume level be different by using different LOC? I am using sd400/4v2 amplifies.
Check your wires for proper polarity, for example left speaker is +/- and right is -/+ make sure it's correct I did the same thing and now it works fine.
Divine Ebbat Thank you. After some debugging i got to know there is a gain control on PAC lp3-2 and that was set as low. After adjusting to maximum sound was back to normal.
I have a request. Can you make a vedio for a 2000 Lexus ES300 model. I really want to upgrade all my speaker systems. But I want to keep my stock radio cassette player. It would be a great help for me as I am very much interested and like your work. It's so neat. Please make a vedio on this vehicle model.
So I installed a loc into what I assume are the correct wires but I get no audio. Every diagram I have say it’s the same wires but when I look at em for example it say blue/white and it’s not really white it’s like Blue yellow
Will I still have to run the remote wire from my amp to my fuse box with add a circuit? Even if I have this LOC? Or just run the remote wire from the LOC to the amp?
I am on my second p a c LP 7-2. My first was reading very low voltage. My second one did the same thing, I'm trying to target 2v but the highest reading is 0.017 ac.volts on both converters. I used two different multimeters with the same reading. My car is 08 Acura TL and I tapped into the rear speaker. I know for a fact I have it hooked up correctly. Do you know what's going on?
If you are using AGU fuses use a continuity check on your fuses, they are notoriously unreliable with their end connections. Fuse looks fine but not actual connection.
Makes sense now my line output converter never had a ground wire to cancel out the humming from my subs happens sometimes and other times I turn the car on doesn’t happen I have to get one with a ground wire
Great video! I have 05' GMC Yukon Denali w/ the premium Bose system and scratching my head as to where I tap the yellow 12v power and blue remote turn on wire from my PAC LP6-2R LOC? Do I run them directly to my aftermarket amp or do i need to tap them into my corresponding factory wires?
So I'm installing a PAC LP6-2R to my 05' Yukon Denali with premium Bose system. And want to retain my premium Bose system for my factory speakers and sub. All I'm trying to do is add a aftermarket subwoofer and amp. I've got everything connected w/ the PAC LP6-2R LOC, MEMPHIS AUDIO 1000watt amp, and kicker comp R subwoofer but no sound The only reason i can think of it not working is I've only got the left speaker + and - connect to the back of my H/U... Does both channels need to be connected to work ?
Im having a boooom if i cut off my radio do i need to ground the 2 brown wires on my PAC SNI-35 ADJUSTABLE 2 CHANNEL LINE OUT CONVERTER SPEAKER WIRE HI LOW RCA SNI35 ?
As a Formally Trained Audio Engineer and a guy who cut his teeth doing car stereos I thought that was actually a pretty good breakdown for folks that don't have an electronics background or a lot of inclination to get deep on how all this audio stuff works. I employed one of these adapters in a Bar where the Owner asked if I could run the output of his Jukebox (which only had a Left and Right External Speaker Output) into the speakers He had in the ceiling (or more correctly to the amp that powered those speakers) and it worked beautifully - also it's great because it mirrors the volume of its source relatively speaking. Not sure why this got so many thumbs down - I thought it was fairly spot on. Also for the record this doesn't replace the speakers in the circuit - it sits in parallel with the speakers (a "tap" so to speak) which keep the Ohm load correct to the amp - You'll have much more success than trying to completely use this device by itself without those speakers. - MM in Denver CO
U have several questions and cannot find a utube that is specific to it... 1 - Do I have to use the Power Yellow and the Remote Blue cable if my Amp already has it ? Meaning all I will need to connect is the Speaker wire. 2 - I have the PAC LP7-4 L.O.C. PRO Series 4-Channel device, I'm only going to tap in the rear speakers, so I will use 2 channel on the PAC, can I just twist the other two channels together ? Meaning I will use the White and Gray for the 2 channels, can I just twist the Green to the White and the Purple to the Gray for all 4 channels and then go all 4 channels to my amp RCA ? 3 - The the Gain on the PAC will only have the adjustment on one side which is the Right and Left Rear Or Front ? or would I need to adjust both Gains to the same ?
Download some test tones, use an RMS voltmeter in AC mode and set the factory radio at half volume. You should have consistent voltage ratings across the spectrum of test tones if not you can test to see what frequencies the output is trimming.
I have a 2021 Nissan Sentra sv. I’m planning on replacing my speakers and adding a 4 channel amp. Will an LOC or the speaker harness cause any issues with phone calls or anything that goes through my speakers?
Do LOCs increase the output voltage on the amp since the amp amplifies the low level signal, by increasing the low level signal let's say from 2v to 8v, shouldn't the amp hypothetically output 120v instead of 85v? (I'm using generic numbers, very similar to what my 2 Taramps Bass 8Ks output.
Nothing wrong with high level. The key is. If you have to extend the speaker wire. Use “cross link wire”. No voltage drop with them. More expensive though.
OKAY this is what i needed so i did the same thing with my rear deck speakers and i had a high level output harnas for months. And today i wired the 4 wires to my LOC and connected it now my amp nor subwoofer will turn on
Your amp using high level input probably had audio signal sense turn on. You will need to double check your owners manual to see if it is possible to have signal sense turn on using RCA inputs, if it doesn’t you need to run a remote turn on wire.
I have a 2017 lexus is300 I wired the loc to the factory amplifer 8 inch woofer wires left and right together since I only have one 8inch factory sub. Will this be OK or would my signal be weak because I don't have a left amd right signal
Hooked up a sub and amp to my factory dodge Dakota. Not using a LOC! I just spliced into my rear speakers on the door with speaker wire and converted the ends to RCA plugins. Seems to work fine. The bass hits. But when I turn up the volume quick it cuts out and loses bass. I then have to turn down bass on the radio for the sub bass to kick on again. Why is this happening? Thanks.
Installed this today. 2012 Malibu rear speakers. Loc will not shut off for 10 min tho I think it's the radio. I would understand if it was connected to front drivers due to chime. I may have to put mine on acc 12v
I have a 2016 Cadillac CTs vsport with Bose 13 premium speakers and factory amp my questions are what’s the best loc to use? I’ve tried the lc2i and keyloc on my old Cadillac ats when just adding a subwoofer, but if I wanted to change the door speakers and use a four channel amp, is there a way to bypass the factory amp or can I just replace the front speakers with some more high output speakers that I have, and keep the factory amp?
i’m trying to install two 10 inch subwoofers to my car and i don’t know too much about installing speakers, if you’re tapping the two speakers in the trunk like you did in the video, what do i need to do to the head unit?
I'm still very very confused. I have 2 kenwood 12s and 2 amps. I'll be running about 2500 watts to the subs. Will the converter be able to handle that?
what if you have only one speaker (sub) on the back. can you connect the two positives and two negatives on LOC (front and rear ) to the single wires from the speaker?
You should always keep that in the back of your mind. That when in most cases, when dealing with car audio a yellow is always gonna be a constant. Twelve volt and black more than likely most of the time is a ground.
I will say, which he stated as well that the factory deck does make a difference in outputs signals to different speakers so go for whats best. I have a 2017 wrx and have had nothing but trouble so far with my system. First I bought the PAC LP7-2 and honestly sounded like crap. My sub didn't sound nowhere near what it sounded like I'm my truck with aftermarket deck and everything. So I purchased a Skorpion LOC which did help a lot more but still wasn't "clean" bass. Used the Skorpion LOC before in a different car and worked amazing But not for my wrx. Next step would be the audio control LC2i active LOC. Main reason for this long comment, any amp takes about 5 volts input signal to the amp. The PAC LP7-2 only puts out about 1.6 volts. Audio control LC2i puts out almost 7 volts! Little more than needed and for 40 bucks more the than PAC, you do the math. May be the reason why you might have sound quality issues as well. You pay for what you get. In some applications its perfect but others, no. Worked on car audio for 7 years now and learned to much crap on my own. Even the hard way. Hope this helps👍
I have a 2017 STI Base Model and I have been looking at upgrading my sound system. I went to many car audio shops in my area and I've been getting different recommendations from each of them. Anyway, I want to keep my stock head unit, so some of them recommended me to get an LC7 and some of them told me just to get this Line Output Converter. I am really confused on who should I listen to. I feel like some of them just want my money and don't really care what the outcome is gonna be for my sound set up. So idk if i wanna do just the LOC or an LC7.
If you're not getting a clean signal, then you're not getting a great crossover or the source signal doesn't possess the range needed for the output speaker. Crossovers designate which frequencies go to which speakers, and are usually necessary to give an aftermarket system a truly "clean" sound. It will only allow the target speaker(s) to produce the specified frequencies. Again, it also matters where the source frequencies are coming from.
I have the opposite problem. I have an aftermarket head unit with RCAs out and I would like to use a stock stereo I have sitting around because it fits the area. How do I do that?
Can i just go off the passenger rear speaker on my 14 dodge ram. Used the loc2. Just not sure if im not getting full range by not going on driver side as well
If the blue Remout ON wire is connected to a constant power like in your installation, the amplifier will be ON all the time and may drain your car battery when the car is not running. Is it better to connect the blue wire to an "Accessory" or "Ignition" power?
I've been trying a reverse to this without much success, converting pre-out RCA from my head unit to line-level to feed the factory amplifier, it's good enough for me. Originally with the high-line output to the amp it was too loud, as you'd expect but now with the pre-out it's too quiet at full volume. Not sure how I can find a middle ground. The amplifier in the head unit should be good enough as it's a new high-end Alpine unit so I'm tempted to rip out the factory amp and install passive crossovers instead for my 12 speakers. Still considering my options.
I have similar setup as you. I have problem that playing music wakes amp, but playing radio does not. Do you have problem waking factory amp with aftermarket head unit?
Can you use this if you got a aftermarket radio? I was thinking about buying a SC6 line output signal converter. But I only wanted to use it for having the max input voltage for my sub amp and my 4 channel. I could just plug rca in from aftermarket radio and rca out to the amps?
So as long as you’ve already got a rem wire going to accessory, you don’t need to use the rem wire on the converter? And so long as you got clear sound, you don’t need to use the brown ground wire?
I've watched vids where they cut the wire right next to the factory stereo and then others that did your way. Can I connect the LOC directly from each speaker rather than cutting the factory harness? And do I have to connect all the speakers to the LOC?
If my aftermarket radio has a front rca output and a rear/SW output, would it be a good idea to use Y rca cables to split the signal so I can connect both the sub amp and the front and rear amp? Or should I convert the high level outputs to Low level RCA and use that as my outputs
So you hooked up both rear speakers to the LOC?? I had mine installed "Profesionally" and they only hooked up the 1 side should I redo it to have both for better sound and quality? I have aftermarket rear speakers as well and a amp and sub, amp is only for the sub. TIA
I have a 2011 murano with the factory bose amp and sub. Can I tap into the amp to hook up the loc? All I'm looking to do is add another amp and 12 inch sub. I would run separate power from the battery. Looking for some ideas thanks
Do you only need to use 1 speaker when tapping in to them? Or do you need to use 2 speakers? I have mine set up running off of my right front door speaker. But it’s seems that I am only getting single, or power, or very week response out of one of my subwoofers. Thanks in advance for any help!
a little confused with the wattage. first time i would be using a LOC. if i have a 750 watt amp and 800watt sub and the amp is still pulling directly from the battery so power wise its good does it matter if the LOC is only 400watts? my guess is no since the amp would still amplify and send 750 to the sub. would LC2i be enough?
I'm looking for a wire harness for a 2012 Infiniti QX56. I'm trying to run the RCA from the front of the truck. It's to add the complete system, crossover, amps for mid/high and a bass amp. I have search all over for the wire harness and can't find one. Any ideas on where I can find this in Florida?
Do you recommende LP7-2 over LP7-4? My question is if I want to keep the balance of my stock stereo with an Amp but with additional Amp to a Subwoofer.
Can you still use the PAC LP7-2 if you are tapping stock amplified 2ohm leads? replacing the 2ohm full range speakers with the LP7-2? Will this great an issue with the existing untouched existing 8 speakers.?
Great video!!!! I'm so glad you showed the guts of the LOC and explained the internal parts. It really helps people like me to understand better. Thank you !!
I have 1200watts Car Stereo, and I have 4stock car speakers, and I want to add 400watts woofer and 2-speaker 2way 800watts ...so total speakers are 7 .will.it works/connect to my stereo?
Mono block amp? Is there an advantage to wire 2 rear speakers to the LOC or can i wire just 1 speaker output to both +and- of the LOC if just used for a Subwoofer amp?
nice video, a quick question, i have 2 amplifiers 1 for my door speakers which i understand for low line output converter is installed on stock radio, but for my subwoofer amplifier where do i connect signal wire for a low line output rca to my amp? thanks hope you can help
So I want to put this set up "Rear speakers and a sub" with el 4 channel amp RockFord Fosfate R400. Do I need a 4 channel line output converter and the same process of tapping the rears? How do I wire for 4 channel tapping the rear
I have a corolla 2015 with after market-powered sub. The part where you connected the remote turn on for the amp was on the LOC, I dont have an LOC on my arrangement just a powered sub.. if you can please help me with where to connect that? thanks
What I’m looking for is the opposite! 🤦♂️ i have RCA out pout from my kenwood (3 pairs) and I want to connect them to my speakers without an amp! There will be just 1 mono amp for the subwoofer so I want to connect the front and rear speakers to the head unit with an RCA so I can enable the X’ over from my Kenwood Excelon DDX9906XR! Please advise 🙏
please help me you keep saying stock stereo dose that mean this only works with a stock stereo .... what i want to use this is for my aftermarket car stereo that only as only 2 rca outs (a single left and a single right) would i be able to wire this in to my front left speaker and right front speaker to make my front speakers amplified ?
Hey folks I have a question I just purchased A MTX terminator two 12s in 1 boxand the amp is 1200 Watts also terminator. I have it in my 2003 Pontiac grand am. I feel like it's not beating to it's full potential so I went back over my wiring and the h-l-i cord is not hooked up. Am I supposed to run new wire from back of radio to the hli piece or how do I hook up that part? Please help ASAP. SHOULD I BUY NEW AMP OR DID I DO SOMETHING WRONG???
Hey guys thanks for all that information! I still have a question tho... I’m about to install a Kenwood 6 channel amp on my 2017 Honda Accord that has the 4 speaker only factory system, so far so good right... 4 channels from factory HU to the amp then out to 4 speakers... my question is, what channel from the factory stereo/hu should feed the subwoofer since all 4 are taken?? Do I split the signal from the LOC’s RCA output so I can feed the subs input rca on the amp? What do you recommend I should do? If I get a six channel LOC I face the same problem only at the inverse. What type of solution do you recommend? Your help is greatly appreciate it!!! :)
@@Qualitymobilevideo so.. i just can figure it out on my new modification to my installation.. it worked previously. My system look like this. 1, 4 channel amp (Rockforf Fosgate P400-4) 1, 1 channel amp (Rockford Fosgate P1000x1Bd) 1, 4 channel LOC (NVX XPLOC4) 1, Rockford Fosgate RFI2SW RCA adapter My last known "good" installation was hooked up like this. High level signal coming from factory IAM going in to LOC. From LOC front channels output to front channel input on 4ch amp. From LOC rear channels output to 1ch input From 1ch amp pass through output to rear channels input on 4ch amp. 12v and ground to LOC remote from LOC to 1ch amp and 4ch amp. Have been working good. Now i decided to try something new. My 1ch amp has highlevel signal capable RCA inputs and can be used by connecting high level speaker wires from IAM to a RCA-adapter cable. Then i can ditch the 12v, ground and remote from LOC and instead use 1ch amps remote out built in and active when amp signal sensing. I have followed the instructions for LOC, 1ch amp and the adapter cable. I just cant get it to work. Im so annoyed and frustrated. I have some pictures how ive done it. Its like a worm nest looking but.. Also measured with DMM ground on ground on the RCA plugs and chassi ground, measured on amp 12v and ground, measured on positive pin on rca plug and ground on rca shield. Measured on speaker wires signal from IAM Amp are not turning on, no signal, no lights.. nothing. What have i done wrong? what am i missing? how do i diagnose further? How can i upload and show pictures? or can i send them in private somehow?
Roxshot Use a test tone disc and DMM.Test 40hz...400hz.....1000hz......4000 hz at the same volume level.If the voltage output is basically the same for each frequency then you've got a full range signal.If say 40hz has a much higher voltage reading than 400hz than that signal has a low pass filter on it....etc
can someone help me i put a converter but it wont send signal it does whes factory speakers are conected but i also put a 4 ch amp for new speakers it turns on then cut out if i shut of i wont come on again
Do you know if the 2015 and up Dodge Chargers SXT rear speaker wires are full range? I want to connect Audio Control LC7i or DQ-61 so I can connect 3 amps each for high, mids and lows from the just rear speaker signal.
I have subs installed to my stock radio but now I have a aftermarket head unit was wondering how I use a universal bass knob without having any rcas going to the head unit since I still have my line output converter
I have a 2018 Accord lx. I took a monoblock amp and a Kicker L7 out of my Tundra that absolutely pumped I use the same line output converter that you have in the video with the remote turn on I kicked the gain all the way up on the line out converter and the amp and it barely puts any sound out I don't know what to do???🤯 I also disconnected the noise cancelling system behind the glove box but it's like the Accord does not put much bass sound through the rear speakers so I don't have a good enough signal I have no clue what to do I'm about to rip it all back out of the car
Amazing vid my speakers pop when I turn it up after turning up the volume. Also there is no bass to the subwoofer ( I’m only running a sub to a 4 channel amp) can you help me out?
I thought this shop was trying to get more money out of me but i see I actually need it for my factory radio . Appreciate you clearing it up
This guy's install and explanation videos are the best. At this point I watch for entertainment purposes
I like that you said that because after finding the help I've bee needing , I think I'll start showing up more often.
This helped me to do this. Home theater AV receiver --> frontal main speakers --> LOC --> stereo amplifier --> One pair of speakers. Now I can use only one pair of main speakers for music and for movies and games. I don't see this solution very often. Thank you.

After countless hours of sleepless nights and hours of research with a tight budget, I wanted to have the best setup which suited my needs. Clear Full Range Music(EQ control) with Accurate BASS.

Question.
Car with fiber optic amplifier systems to upgrade sound unit to aftermarket Sony or alpine.. Etc how can used the original amplifier with fiber optic cable, or delete all systems or what the best solution or option I have.
im planning on doing something like this on my 00 323i. My rear deck speakers are blown as of right now and im thinking of just using the wires from that, and putting an loc in my trunk with the rear deck speaker wires running to it. Then running rca to my amp. Do you think it would work?
Pretty much every amplifier has high level inputs. What advantage does a line output converter have?
No all input stages are created equal. High quality LOC's are generally better.
I wish you were in my area with this kind of professionalism
So, I cut the right front speaker wires from the factory unit.. now I connect the wires to the LOC and then use the other side of the speaker wires and run it to the amp?
You are the real MVP for this video I tapped my Bose base speaker and all I get it base in my mids I'm gonna try the lci2
Woo!
In addition to running speaker wires from the LOC to the car speaker wires, I just realized I ran an additional set on both car speakers and ran them into the speaker terminals on the sub amplifier obviously where the sub speaker wires go into. The sub works and sounds great I just don’t know if there’s any issues to having another set of wires on each side of the car speakers running into the speaker terminals on the sub amplifier
My car has a single factory subwoofer in backdash. Should I just tap both left n right positive as 1 and the negatives as 1?
yes.
Thanks man , I have a question. I tapped in to my factory subwoofer but my PAC LP7-2 won’t play a beat. I’m guessing it doesn’t pick up those frequencies right? Should I upgrade to a LC2-I
Quick question I got the kicker version of this loc which has the remote wire. But my question is, is it OK to tap into the stock OEM subwoofer connection? Is it too much power for that little device or will it be OK? It’s the stock amp and subwoofer plug in the back of the mega cab behind the seats . Just because it’s easy to access is why I’m asking
Why do you wire LOC converter to the wires coming out from the factory amplifier instead of wire in before the factory amplifier?
Is there much difference in reality?
Please answer my dumb question?
I was using RF-HLC4 LOC and the front left speaker was cutting in and out sometimes on low volume. Then i replaces the loc with PAC LP3-2 prod and the sound is too low.
Gain settings in the amplifier is same but the sound is very low. Can the volume level be different by using different LOC?
I am using sd400/4v2 amplifies.
Check your wires for proper polarity, for example left speaker is +/- and right is -/+ make sure it's correct I did the same thing and now it works fine.
Divine Ebbat Thank you. After some debugging i got to know there is a gain control on PAC lp3-2 and that was set as low.
After adjusting to maximum sound was back to normal.
I have a request. Can you make a vedio for a 2000 Lexus ES300 model. I really want to upgrade all my speaker systems. But I want to keep my stock radio cassette player. It would be a great help for me as I am very much interested and like your work. It's so neat. Please make a vedio on this vehicle model.
I have factory woofers that has 8 ohms can I use this signal through one of there LOC? Will it matter that my amp is 4 ohms?
So I installed a loc into what I assume are the correct wires but I get no audio. Every diagram I have say it’s the same wires but when I look at em for example it say blue/white and it’s not really white it’s like
Blue yellow
Will I still have to run the remote wire from my amp to my fuse box with add a circuit? Even if I have this LOC? Or just run the remote wire from the LOC to the amp?
With this LOC no, you this has a turn on out circuit.
I am on my second p a c LP 7-2. My first was reading very low voltage. My second one did the same thing, I'm trying to target 2v but the highest reading is 0.017 ac.volts on both converters. I used two different multimeters with the same reading. My car is 08 Acura TL and I tapped into the rear speaker. I know for a fact I have it hooked up correctly. Do you know what's going on?
If I got a 6 speaker in/out converter but I only have 4 speakers, is that ok or should I get a 4 in/out?
Yes, no problem. You will not use two of them.
Why would I get power to the inline 8 gauge fuse from my truck battery but no power from the fuse to my amp? But the fuse is good.
If you are using AGU fuses use a continuity check on your fuses, they are notoriously unreliable with their end connections. Fuse looks fine but not actual connection.
Makes sense now my line output converter never had a ground wire to cancel out the humming from my subs happens sometimes and other times I turn the car on doesn’t happen I have to get one with a ground wire
Great video! I have 05' GMC Yukon Denali w/ the premium Bose system and scratching my head as to where I tap the yellow 12v power and blue remote turn on wire from my PAC LP6-2R LOC? Do I run them directly to my aftermarket amp or do i need to tap them into my corresponding factory wires?
Yellow is a direct battery connection, Blue will be the output to your amp remote turn on.
So I'm installing a PAC LP6-2R to my 05' Yukon Denali with premium Bose system. And want to retain my premium Bose system for my factory speakers and sub. All I'm trying to do is add a aftermarket subwoofer and amp. I've got everything connected w/ the PAC LP6-2R LOC, MEMPHIS AUDIO 1000watt amp, and kicker comp R subwoofer but no sound The only reason i can think of it not working is I've only got the left speaker + and - connect to the back of my H/U... Does both channels need to be connected to work ?
Im having a boooom if i cut off my radio do i need to ground the 2 brown wires on my PAC SNI-35 ADJUSTABLE 2 CHANNEL LINE OUT CONVERTER SPEAKER WIRE HI LOW RCA SNI35 ?
How do you find out which ones have full range output the rear or front?
You will need to use an RTA and scope the speaker wires.
As a Formally Trained Audio Engineer and a guy who cut his teeth doing car stereos I thought that was actually a pretty good breakdown for folks that don't have an electronics background or a lot of inclination to get deep on how all this audio stuff works. I employed one of these adapters in a Bar where the Owner asked if I could run the output of his Jukebox (which only had a Left and Right External Speaker Output) into the speakers He had in the ceiling (or more correctly to the amp that powered those speakers) and it worked beautifully - also it's great because it mirrors the volume of its source relatively speaking. Not sure why this got so many thumbs down - I thought it was fairly spot on. Also for the record this doesn't replace the speakers in the circuit - it sits in parallel with the speakers (a "tap" so to speak) which keep the Ohm load correct to the amp - You'll have much more success than trying to completely use this device by itself without those speakers. - MM in Denver CO
Thanks bud!
U have several questions and cannot find a utube that is specific to it...
1 - Do I have to use the Power Yellow and the Remote Blue cable if my Amp already has it ? Meaning all I will need to connect is the Speaker wire.
2 - I have the PAC LP7-4 L.O.C. PRO Series 4-Channel device, I'm only going to tap in the rear speakers, so I will use 2 channel on the PAC, can I just twist the other two channels together ? Meaning I will use the White and Gray for the 2 channels, can I just twist the Green to the White and the Purple to the Gray for all 4 channels and then go all 4 channels to my amp RCA ?
3 - The the Gain on the PAC will only have the adjustment on one side which is the Right and Left Rear Or Front ? or would I need to adjust both Gains to the same ?
Hey guys, what's the easiest way to check if a factory is outputting a full range signal output?
Download some test tones, use an RMS voltmeter in AC mode and set the factory radio at half volume. You should have consistent voltage ratings across the spectrum of test tones if not you can test to see what frequencies the output is trimming.
I have a 2021 Nissan Sentra sv. I’m planning on replacing my speakers and adding a 4 channel amp. Will an LOC or the speaker harness cause any issues with phone calls or anything that goes through my speakers?
Do LOCs increase the output voltage on the amp since the amp amplifies the low level signal, by increasing the low level signal let's say from 2v to 8v, shouldn't the amp hypothetically output 120v instead of 85v? (I'm using generic numbers, very similar to what my 2 Taramps Bass 8Ks output.
Brandon, No, they convert speaker level high voltage (8-50 volts) signal to low level RCA signals (200mv - 8 volt).
Are the high level inputs generally quieter than the loc
Nothing wrong with high level.
The key is. If you have to extend the speaker wire.
Use “cross link wire”. No voltage drop with them. More expensive though.
Are there any benefit of using powered LOC over non-powered LOC?
OKAY this is what i needed so i did the same thing with my rear deck speakers and i had a high level output harnas for months. And today i wired the 4 wires to my LOC and connected it now my amp nor subwoofer will turn on
please help
Your amp using high level input probably had audio signal sense turn on. You will need to double check your owners manual to see if it is possible to have signal sense turn on using RCA inputs, if it doesn’t you need to run a remote turn on wire.
I have a 2017 lexus is300 I wired the loc to the factory amplifer 8 inch woofer wires left and right together since I only have one 8inch factory sub. Will this be OK or would my signal be weak because I don't have a left amd right signal
Hooked up a sub and amp to my factory dodge Dakota. Not using a LOC! I just spliced into my rear speakers on the door with speaker wire and converted the ends to RCA plugins. Seems to work fine. The bass hits. But when I turn up the volume quick it cuts out and loses bass. I then have to turn down bass on the radio for the sub bass to kick on again. Why is this happening? Thanks.
Installed this today. 2012 Malibu rear speakers. Loc will not shut off for 10 min tho I think it's the radio. I would understand if it was connected to front drivers due to chime. I may have to put mine on acc 12v
I have a 2016 Cadillac CTs vsport with Bose 13 premium speakers and factory amp my questions are what’s the best loc to use? I’ve tried the lc2i and keyloc on my old Cadillac ats when just adding a subwoofer, but if I wanted to change the door speakers and use a four channel amp, is there a way to bypass the factory amp or can I just replace the front speakers with some more high output speakers that I have, and keep the factory amp?
i’m trying to install two 10 inch subwoofers to my car and i don’t know too much about installing speakers, if you’re tapping the two speakers in the trunk like you did in the video, what do i need to do to the head unit?
Outstanding video. Perfectly explained. Thank you very very much.
I'm still very very confused. I have 2 kenwood 12s and 2 amps. I'll be running about 2500 watts to the subs. Will the converter be able to handle that?
what if you have only one speaker (sub) on the back. can you connect the two positives and two negatives on LOC (front and rear ) to the single wires from the speaker?
He said 20,000 KHz....lol Just bustin' your chops, man; Your vids are awesome!! Sparks in Daytona
Thanks!
Finally a clear answer on the yellow and black wires! No other videos cover that.,
Glad it helped Chris!
You should always keep that in the back of your mind. That when in most cases, when dealing with car audio a yellow is always gonna be a constant. Twelve volt and black more than likely most of the time is a ground.
I will say, which he stated as well that the factory deck does make a difference in outputs signals to different speakers so go for whats best. I have a 2017 wrx and have had nothing but trouble so far with my system. First I bought the PAC LP7-2 and honestly sounded like crap. My sub didn't sound nowhere near what it sounded like I'm my truck with aftermarket deck and everything. So I purchased a Skorpion LOC which did help a lot more but still wasn't "clean" bass. Used the Skorpion LOC before in a different car and worked amazing But not for my wrx. Next step would be the audio control LC2i active LOC. Main reason for this long comment, any amp takes about 5 volts input signal to the amp. The PAC LP7-2 only puts out about 1.6 volts. Audio control LC2i puts out almost 7 volts! Little more than needed and for 40 bucks more the than PAC, you do the math. May be the reason why you might have sound quality issues as well. You pay for what you get. In some applications its perfect but others, no. Worked on car audio for 7 years now and learned to much crap on my own. Even the hard way. Hope this helps👍
I have a 2017 STI Base Model and I have been looking at upgrading my sound system. I went to many car audio shops in my area and I've been getting different recommendations from each of them. Anyway, I want to keep my stock head unit, so some of them recommended me to get an LC7 and some of them told me just to get this Line Output Converter. I am really confused on who should I listen to. I feel like some of them just want my money and don't really care what the outcome is gonna be for my sound set up. So idk if i wanna do just the LOC or an LC7.
@@BinaryBroadcast The speaker level inputs of an amp are the same thing as a LOC so I never understand why people use LOC's if their amps have HLI's?
If you're not getting a clean signal, then you're not getting a great crossover or the source signal doesn't possess the range needed for the output speaker.
Crossovers designate which frequencies go to which speakers, and are usually necessary to give an aftermarket system a truly "clean" sound. It will only allow the target speaker(s) to produce the specified frequencies.
Again, it also matters where the source frequencies are coming from.
I have the opposite problem. I have an aftermarket head unit with RCAs out and I would like to use a stock stereo I have sitting around because it fits the area. How do I do that?
Can i just go off the passenger rear speaker on my 14 dodge ram. Used the loc2. Just not sure if im not getting full range by not going on driver side as well
If the blue Remout ON wire is connected to a constant power like in your installation, the amplifier will be ON all the time and may drain your car battery when the car is not running. Is it better to connect the blue wire to an "Accessory" or "Ignition" power?
I hope u read and reply to my question. I have 2 channel stereo without line level out how do I use this device for add Com.
I've been trying a reverse to this without much success, converting pre-out RCA from my head unit to line-level to feed the factory amplifier, it's good enough for me. Originally with the high-line output to the amp it was too loud, as you'd expect but now with the pre-out it's too quiet at full volume. Not sure how I can find a middle ground. The amplifier in the head unit should be good enough as it's a new high-end Alpine unit so I'm tempted to rip out the factory amp and install passive crossovers instead for my 12 speakers. Still considering my options.
I have similar setup as you. I have problem that playing music wakes amp, but playing radio does not. Do you have problem waking factory amp with aftermarket head unit?
do you just connect the constant 12v to the power wire from the battery? and also connect it right to the ground connection on the amp itself?
so if i want to put a 1 channel bass amp and a 4 channel voice i got to buy 2 converters then?
No, buy a 4-channel LOC and Loop it through your 4-channel amp or use y-connectors if your 4-channel does have outputs.
Hello, is this adapter able to reduce chime noise (like turn signal, parking sounds) ?
Can you use this if you got a aftermarket radio? I was thinking about buying a SC6 line output signal converter. But I only wanted to use it for having the max input voltage for my sub amp and my 4 channel. I could just plug rca in from aftermarket radio and rca out to the amps?
This helped a lot! I got a used 2016 buick regal pre wired for a amp and sub and got lost when I saw the loc. I thought I was doing something wrong.
I was hoping you were going to tune it. Im not sure the relation between the gain on my monoblock and the gain on the line out converter
So as long as you’ve already got a rem wire going to accessory, you don’t need to use the rem wire on the converter?
And so long as you got clear sound, you don’t need to use the brown ground wire?
I've watched vids where they cut the wire right next to the factory stereo and then others that did your way. Can I connect the LOC directly from each speaker rather than cutting the factory harness? And do I have to connect all the speakers to the LOC?
How do you know if your amp can decipher hi and low from a simple rca split from a line output converter? What would be in description on amp ?
If my aftermarket radio has a front rca output and a rear/SW output, would it be a good idea to use Y rca cables to split the signal so I can connect both the sub amp and the front and rear amp? Or should I convert the high level outputs to Low level RCA and use that as my outputs
So you hooked up both rear speakers to the LOC?? I had mine installed "Profesionally" and they only hooked up the 1 side should I redo it to have both for better sound and quality? I have aftermarket rear speakers as well and a amp and sub, amp is only for the sub. TIA
I have a 2011 murano with the factory bose amp and sub. Can I tap into the amp to hook up the loc? All I'm looking to do is add another amp and 12 inch sub. I would run separate power from the battery. Looking for some ideas thanks
Do you only need to use 1 speaker when tapping in to them? Or do you need to use 2 speakers? I have mine set up running off of my right front door speaker. But it’s seems that I am only getting single, or power, or very week response out of one of my subwoofers. Thanks in advance for any help!
a little confused with the wattage. first time i would be using a LOC. if i have a 750 watt amp and 800watt sub and the amp is still pulling directly from the battery so power wise its good does it matter if the LOC is only 400watts? my guess is no since the amp would still amplify and send 750 to the sub. would LC2i be enough?
Great video, if I were wiring my LOC behind the radio where would I get my power from?(yellow cable)
I'm looking for a wire harness for a 2012 Infiniti QX56. I'm trying to run the RCA from the front of the truck. It's to add the complete system, crossover, amps for mid/high and a bass amp. I have search all over for the wire harness and can't find one. Any ideas on where I can find this in Florida?
Do you recommende LP7-2 over LP7-4? My question is if I want to keep the balance of my stock stereo with an Amp but with additional Amp to a Subwoofer.
Can you still use the PAC LP7-2 if you are tapping stock amplified 2ohm leads? replacing the 2ohm full range speakers with the LP7-2? Will this great an issue with the existing untouched existing 8 speakers.?
Great video!!!! I'm so glad you showed the guts of the LOC and explained the internal parts. It really helps people like me to understand better. Thank you !!
Wooo! Glad it helped you out!
but I want to run an aftermarket kenwood amp what watts can I use with this rca

Mono block amp? Is there an advantage to wire 2 rear speakers to the LOC or can i wire just 1 speaker output to both +and- of the LOC if just used for a Subwoofer amp?
nice video, a quick question, i have 2 amplifiers 1 for my door speakers which i understand for low line output converter is installed on stock radio, but for my subwoofer amplifier where do i connect signal wire for a low line output rca to my amp? thanks hope you can help

I have a corolla 2015 with after market-powered sub. The part where you connected the remote turn on for the amp was on the LOC, I dont have an LOC on my arrangement just a powered sub.. if you can please help me with where to connect that? thanks
What I’m looking for is the opposite! 🤦♂️ i have RCA out pout from my kenwood (3 pairs) and I want to connect them to my speakers without an amp! There will be just 1 mono amp for the subwoofer so I want to connect the front and rear speakers to the head unit with an RCA so I can enable the X’ over from my Kenwood Excelon DDX9906XR! Please advise 🙏
Can you make a video on how to run the remote wire the yellow and blue wire
please help me you keep saying stock stereo dose that mean this only works with a stock stereo .... what i want to use this is for my aftermarket car stereo that only as only 2 rca outs (a single left and a single right) would i be able to wire this in to my front left speaker and right front speaker to make my front speakers amplified ?
Hey folks I have a question I just purchased A MTX terminator two 12s in 1 boxand the amp is 1200 Watts also terminator.
I have it in my 2003 Pontiac grand am.
I feel like it's not beating to it's full potential so I went back over my wiring and the h-l-i cord is not hooked up.
Am I supposed to run new wire from back of radio to the hli piece or how do I hook up that part? Please help ASAP.
SHOULD I BUY NEW AMP OR DID I DO SOMETHING WRONG???
So I know attach the remote wire from the LOC to the amp. What about the remote wire from the dash?
My problem is the noise, whining sound and other noise from the line converter… so annoying and I’ve tried a ground loop isolator
Nice video, very professional and informative. Thanks for taking the time to make a great video!
Glad it helped!
Hey guys thanks for all that information! I still have a question tho... I’m about to install a Kenwood 6 channel amp on my 2017 Honda Accord that has the 4 speaker only factory system, so far so good right... 4 channels from factory HU to the amp then out to 4 speakers... my question is, what channel from the factory stereo/hu should feed the subwoofer since all 4 are taken??
Do I split the signal from the LOC’s RCA output so I can feed the subs input rca on the amp? What do you recommend I should do?
If I get a six channel LOC I face the same problem only at the inverse.
What type of solution do you recommend? Your help is greatly appreciate it!!! :)
I have some install/reconfiguration questions!
Throw them out at we’ll see
@@Qualitymobilevideo so.. i just can figure it out on my new modification to my installation.. it worked previously.
My system look like this.
1, 4 channel amp (Rockforf Fosgate P400-4)
1, 1 channel amp (Rockford Fosgate P1000x1Bd)
1, 4 channel LOC (NVX XPLOC4)
1, Rockford Fosgate RFI2SW RCA adapter
My last known "good" installation was hooked up like this.
High level signal coming from factory IAM going in to LOC.
From LOC front channels output to front channel input on 4ch amp.
From LOC rear channels output to 1ch input
From 1ch amp pass through output to rear channels input on 4ch amp.
12v and ground to LOC
remote from LOC to 1ch amp and 4ch amp.
Have been working good.
Now i decided to try something new.
My 1ch amp has highlevel signal capable RCA inputs and can be used by connecting high level speaker wires from IAM to a RCA-adapter cable. Then i can ditch the 12v, ground and remote from LOC and instead use 1ch amps remote out built in and active when amp signal sensing.
I have followed the instructions for LOC, 1ch amp and the adapter cable.
I just cant get it to work. Im so annoyed and frustrated.
I have some pictures how ive done it. Its like a worm nest looking but..
Also measured with DMM ground on ground on the RCA plugs and chassi ground, measured on amp 12v and ground, measured on positive pin on rca plug and ground on rca shield. Measured on speaker wires signal from IAM
Amp are not turning on, no signal, no lights.. nothing.
What have i done wrong? what am i missing? how do i diagnose further?
How can i upload and show pictures? or can i send them in private somehow?
@@Qualitymobilevideo trying to paste a link to pictures and manuals but my post gets deleted. Don't know how to come around it.
Very informative video! One question - how did you test for Full Range Output?
Roxshot Use a test tone disc and DMM.Test 40hz...400hz.....1000hz......4000 hz at the same volume level.If the voltage output is basically the same for each frequency then you've got a full range signal.If say 40hz has a much higher voltage reading than 400hz than that signal has a low pass filter on it....etc
can someone help me i put a converter but it wont send signal it does whes factory speakers are conected but i also put a 4 ch amp for new speakers it turns on then cut out if i shut of i wont come on again

In a 4 channel set up do I need to tap each speaker and run it to the LOC?
I have a 2018 Accord lx. I took a monoblock amp and a Kicker L7 out of my Tundra that absolutely pumped I use the same line output converter that you have in the video with the remote turn on I kicked the gain all the way up on the line out converter and the amp and it barely puts any sound out I don't know what to do???🤯 I also disconnected the noise cancelling system behind the glove box but it's like the Accord does not put much bass sound through the rear speakers so I don't have a good enough signal I have no clue what to do I'm about to rip it all back out of the car
