![Why is this 1000W $63 Amp BANNED from Amazon? [4K]](http://i.ytimg.com/vi/4RRyAANKRlw/mqdefault.jpg)
The efficiency difference is an interesting find in the JP8’s. I’ve never wanted to mess with strapping amps together, but this is good info for the folks looking to do something like this.
I think it was a gain matching issue internally with the amps. That would waste a ton of power because of the voltage/output impedance mismatch on each hot terminal. It should have been the same at 2x the load impedance as one amp
The work you do to bring us the truth does not go un noticed . I have had quite a few shocks, no pun intended, about a lot of results from the testing you preform. Keep up the great work.
I reconed some subs for a local guy around Christmas time. They're d1.5 ohm coils. He had a single jp8 originally and now 2 strapped. He's running the amps strapped at 1.5 ohm(series parallel) and they've been solid. Very good power for the money, and reliable. Great video man! 👍
Excellent video as always man!
Thanks brother! Enjoy your Honeymoon and congrats!
I have one of these amps running at 1 ohm powering 2 JL Audio 12TW3-04 subs in my Tundra along with 2 of the JP84 amps powering the rest of my system and I am quite pleased with them. Price has done a good job with these amps. My system is designed to deliver the best sound quality it can and these amps are doing a great job. I was totally unaware of these amps before I saw them being tested on the dyno here on your channel. So thanks for that.
I've been waiting for this for a long time. Thanks. Always good info.
good content as always D......one of my favorite channels, and i always go to see new content on sunday, the only channel i do that for👍👍
I was just talking about strapping this last week and how I have no idea how to do that!! 😊 Definitely think I'd just buy a bigger amp, easier all around it seems. Love the content my man!
Another great video! Love the way the sine waves go with this one. Thanks Big D!
Thank you for the lesson. Always nice to understand our options.
Good video. I've been really wanting to pick up a JP8 since watching your videos on it.
Great Video !! Like always !!
Back in 1991 I bought 3 Phoenix Gold MS amplifiers.A 2125,and 2 -MS-250
( Actually the MS 275 )
I still have them in my closet.
But they had Daisy Chaining back in the day .Master / Slave with a 1/8 plug
Back then it was a big deal .
HEY. ALLL CAPS JOE HERE. THANKS FOR CHANGING THE SIDE CUTS. THAT'S HOW YOU DO IT. WE LOVE YOU
Thank D that was the best strapping video yet

Love my JP amps. Especially the China made ones nothing comes even close to the power and features for the cost plus you still get the same D4S support as you would if you splashed the cash for a Korean model
Can't imagine how many subwoofers will be saved by the clipping indicators, both on the amp during setup and on the remote knob during use
I am so glad someone finally did a strapping video. Thanks for a great episode as usual! I just have to figure out why no BIG D notifications 😮😢
I have another 43 ordered today, and you put out vid on what I was planning, nice👍
Excellent video brotha
Loved this. As Educational as you can get. You always explain stuff in normal language!
Big Dummy speaks!
Thank you Derek for this video. I advise customers of the potential repair costs when strapping amps. Seeing the drop in efficiency lends clues to what is going on.
7-8 years ago, I had two Crescendo amplifiers strapped. The slave failed, and when sent in for repair, I was told that strapping was harder on the input section, as that was what had to be repaired. Once I got it back, I used it as the master, and several months later, the other amp failed. Sent it to another repair person, as the other was backed up. Same issue with that amp, input section. That person said the same. I don't know how true I is, so I will ask you..I follow your repair channel.
@@Chuck_Sanders I advise that both amplifier output sections be replaced if there is an output or sub failure in a strapped installation. Some designs will hold up better than others. If a customer only sends one in I will let them know that the other may have been damaged and to be prepared for a repair bill on it.
@@ellensburgamplifier I'm not sure if the output section had damage, I was advised the input portion had been damaged. It was curiosity as to what may have caused that, and why 2 different individuals would advise that strapping was harder on the input. I'm just wondering if it was board specific, I haven't really strapped any since, and just gain match. Idk why, just made me leary I guess. Any other possible reasons why that may have happened? Thanks for responding
@@Chuck_Sanders The power supply for the most part will never know that the amplifier is strapped. There are several reasons for a supply failure. Power supply failures are mainly from overloads and thermal failures.
@@ellensburgamplifier thank you for the response. It is much appreciated good sir!
Great job on this video
Many years back in the 1990's I was getting into the extra sound in the car system but did not want o spend much, but still wanted good as I could. So I bought the Radio Shack (Realistic) 120 watt 60X2 subwoofer amp. Seeing they could be bridged stereo to one mono channel with the built in switch and wiring instructions and I had a dual voice coil subwoofer in a tube I bought a second one. Found out a few months later they were discontinued and marked down greatly, and made a deal and bought two of the 160 watt amps that looked similar, but without the subwoofer filters.. Some years back I was experimenting with these and wondered if it was possible to bridge the 160 watt even though it was never meant to be. These had built in high level input connections ( meant for the 1960-1980's cars. ) so I just connected the output like the 120 watt amp had said for bridged operation and on the input side I wired in one channel correct positive to positive, and the other channel I found out works if done the opposite way on that channel. Thus it was bridged. They did apparently share a common internal connection like the other amp, but I never traced or looked at the circuit closely to see if I was wright, but a general look inside of the amp cover. I never tried this long term, but the principle should work but obviously bridged always means the bottom ohm load will have to be raised to twice that or the amp will overload. I would suspect even a 1 or 2 ohm resistor linking a second amp could also be functional on a none approved matched amp set, and the input swapped on one as well.
Just picked up a jp23v1.5 in black about 3 weeks ago for 249.00 and that a steal folks ....this amp puts in work ....if you have the electrical to support it .....that being said I replaced a skar rp1500.1....and it was a very good amp ad well but I run an American bass xr12 d2 ...and even though either amp would probably support 2 of these 12s I went ahead and picked up the jp23v1.5 because you can strap/ link it to another jp23v1.5. .....so when the budget allows for another xr12 d2 if I want more power I have that option ....and I am really impressed with the jp clip light is nice to have as well as temperature and voltage meter ....have played it at hight volume for extended periods of time and a out 118 is as warm as it has got .....not sure I have even had the fan to kick on yet .....glad see this vlog so i know around the power I would get if I do get another one and link/strap it ....big thumbs up big d .. .and hey that's my nickname as well
That's insane! I didn't even know amp strapping was a thing until now.
Funny you post this now. Just did my first show with 2 jp23 strapped at 1 ohm.
Awesome video. I’ve always wanted to see some amps strapped on a dyno, and now I have seen one 😂😂 Those amps are so stout
This is how the old NAD amps are designed. I'm not sure about the 3020 series but the 3150 is linkable with 2150 as well the 3155 with the 2155. Into a 4 ohm load we be talking INCREDIBLE power!
Great video, thanks..
Thanks for doing this. I've never tried it.
Yes!! Big "D"!! Ok, I gotta finish this Techmoan video and then some tragedy about space that was announced a few minutes ago (yeah, they title them to sound so ominous and vague, but still love me some space videos/updates)...but then it'll be your turn! Can't wait. Just had to comment before sitting back with my fur-babies and then forget to or something like that. You rock my good man!!! Have a wonderful day and thank you for everything you do! And you too, whoever is smiling and reading this! If you're not smiling.. Grrrrr! Smile! - it makes everyone wonder what you're up to! 😁🍻🌎❤️🌮🎶
Most interesting video because I stopped customizing OP's auto sounds after 30 years @ the turn of the century, when seperate amps were for splitting Bass, Mid and Highs. My focus had turned to building computers and being in the country all we had were phone lines for internet with modems topping out at 56K. I had up to 4 phones and could STRAP each with modem together which would increase the internet speed up to 4 times...
👌😬👍
Oh sweet that's cool. As a kid I dreamed of tapping into my neighbors phone lines to get triple speed music downloads at night when nobody would use the phone.
You mean to tell me I could have made it possible!!?
@@yeahitskimmel Yep as long as each line has a modem and you have an ISP. I had 2 lines that ran to the old farm house and when I built a new house beside it I put in 4 lines. never ended having to use more than 3 because we soon got satellite/cable. Today with high speed/DSL strapping is possible... it's called bridging...also because internet is much faster today there is "split tunneling" where, for example, certain programs and/or Puters can go thru a VPN while others won't.
@@411LED Shotgunning, as it was called by DIAMOND brand. You could also strap a 56k modem with a cell phone. Back in those days,, the software involved would split the file, say 2/3 of the file was handled by your 56K and the last 1/3 was downloaded over cell phone, at the same time. That was on Sprint, before EVDO 3G/WiMax/4G LTE, thus the speeds were in the 13-30K range realistically. As wireless goes, of course, the speed would vary wildly and thus the portion of the file handled by cell phone would always end up taking longer. Basically, a complete disappointment, but hey, it Worked!
@@CheezeCracker Never tried that method, probably because I used beepers till they went obsolete. I do remember the term Shotgun, even used a Diamond External as their Modems were top notch...
Cool to see the definition of “strapping” amps.
Looks like those JP amps are turning out to be pretty reliable. Great video, sir!
….sending them 6x9s running for the hills!
I lol'd at the random big dummy so hard. Your big social wit is impressive 😂. Thanks for the video this is a new concept for me didn't know this was possible. would love an in depth video going in more detail how to do this. Like I wonder if it would work with headphone amps even?
I have never strapped any amps but if you need to, that's really important need to know information there Big D.
Great video
"Wired the Black amp as the Master."
You wrong for that!! Lmao!!! "Socially conscious." That was funny!! I'm glad people can take a joke in this day and age!!
Love the content, Bid D!! We old school guys gotta remind these kids of how we got to where we are today!! Keep it up!!
I just bought a 2nd JP8 just because it was super cheap and have been debating to strap them. I have two single voice coil 2ohm 12's I think I'm gonna do it after seeing this
Always wanted to know this
It is about time someone did this! Big D FTW!
Lol wait @6:30 when you said cause you are subconscious. You wired the black amp as the master and the purple as the slave lol smart choices 😆
I'm gonna have to buy some JP amps this summer.
I had a set of Power Acoustik 12's long while back, DVC ect. Bought them from a buddy because he wasnt happy with them. He didnt quite understand the wiring with DVC style speakers. He was blown away when he could hear me half a mile away.
So instead of explaining and teaching him how, you instead ripped him off basically. Yeah, good buddy, huh?
🙌 💪 thank you Williston audio labs. Run JP amps strapped. ⚡️.
Man I love these videos. Didn't know amp strapping was a thing.
Also, I let a fellow Soldier listen to my system (made using the TopStrongGear) and he instantly wanted me to help him with his. Gotta admit, I wouldn't be back into car audio again if not for you.
Also, he's using the same TopStrongGear amp. 😆 Gotta admit, it's small and powerful!
Do you happen to have any dyno numbers for your amp?
A "1500 watt" amp on Amazon for $120 is obviously too good to be true (especially when the model name is clearly 1100.1) but I'm always interested in Chinese gems that work well enough but are most importantly reliable
And yes I know I may be replying to an Amazon seller shill
@@yeahitskimmel ......the very channel you're watching, has dynod one straight from Amazon. It did VERY well.
Now the one I bought, well after Williston bought his, has the same Caps used by Sundown.
Mine should be within 5% variance to Willistons. As well, it DRIVES my 12" Kicker LT7 - p/n 46TL7T122 at just a hair over 1/2 power.
As for what mine dyno's, not sure. But it f*ckin slams for a single 12 in a small enclosure!
Actually, you could strap any two matching half bridge amps even if they don't have a strapping feature as long as the settings are pretty well matched and you wave a way to invert the phase of the input signal to one of them. If they have a phase inversion switch that would work perfectly; just set one to 0 and the other to 180 then wire them the way you illustrated. Or if the head unit or line driver has a phase inversion feature that only affects one output. The main advantage of strapping imo is the load seeing double the voltage, so you can get up to 4x the power into a given impedance than one of the amps could do into it individually (EG you're in an impedance crunch and can't wire the load low enough to get the most out of the amps individually, strap them instead). Even further you hypothetically could strap two different half bridge amps together depending on how they're grounded internally and how the settings/crossover phase distortion matches up on them
Also amazing stuff as always Big D can't wait for the next one!!
This guy knows what he is talking about. Simple ohms law dictates that doubling the voltage at the same impedance results in quadrupling the power.
@@Nathan-wz4lg wow just learned something new! I did not even think about it like that
So I'm going to strap my amps the right way today they have the feature of strapping and have a slave and master switch also have a phase switch which one should be 0 and 180 master phase zero slave 180 on phase or since they are strappable it is not needed?
The amp in slave should automatically bypass all its settings and the settings on the master amp will control everything. And of course beware of the speaker terminals XD.. what was once a minor shock touching the leads when the amps were cranked may now be something seriously painful haha@@johnoates3326
Thank you
i normally only hook up the inputs for master/slave and invert the polarity of the subs on the slave amp . this gives you the ease of tuning on the master only without the negatives of strapping the subs
You're talking about using multiple amps for multiple loads tho, the intended purpose of strapping is to power a single load with multiple amps
(Edited) I ran 2 Jp23v2s at a final load of 1ohm and got some crazy readings on the amm-1. They can for sure handle it but I still have to say try it at your own risk!
😬👍
Very nice video Derek thanks for sharing the strapping process with us. Have you thought about testing the Black Diamond DIA-K4?
Thanks for the suggestion
@wal it's a small amplifier and looks cool but can it do rated power?
Strapping amp's😂 I must say i just Love your humor 🥳👍
Lol like how you made the Black JP the Master and the Purple JP the Slave very smart there. 😅
Thanks
You should try and do some dyno tests on some nemesis audio amps. I see them around a lot but I haven’t seen any amp dyno tests on their amps so I think it would be nice to see them on your channel
You should do a review and amp dyno of the slapz 5k amplifier I got it for 240 from dealer on slapz audio also I'm getting mine in 2days cheap and what I have seen looks like good amp for the budget but would like to see dyno also I have custom box tune 34hz I do 141db rn on 2400watts on hifonics brx Brutus 2416.1d super class d on 2 sundown x.v3 12" just ordered my 320amp alt and I have it in a 2002 saturn sl2 manual also love the channel been watching for a long long time keep up the awesome work
I've been waiting forever for someone to do a strapped Dyno of some amps. It's always advertised on brands that support it, but hardly anybody ever does a Dyno on them.
BigD Wiz! i have a old hifonics brutus 1700 amp, and i want more power! im considering buying another and strapping just cuz… or should i ditch and snag a CT or other Korean 3k amp? im also trying to make a decision as to what to get for my next setup. ive spent countless hours watching your videos and others trying to come to a conclusion. i love hifonics for the past 15 years id love to see you dyno the 4000.1. thanks for your time - dave
LOL that socially-conscious bit... hilarious😂
Big D, please do dyno on the jp3 555 watt Amp
Damnit Big D are u Psychic I got the JP3/4ab and a Sundown 2k scv seen the matching jp23 thought I can get 2 for the price of one more 2kSCV and sell mine…I didn’t pull the trigger tax sale over… then u post this video… I’m gonna go ahead and get em!!!
Damn. I’ve been out of the loop too long. My last system was 6 Memphis 12”s and three 1000d’s and that sounded nuts in 2012. I didn’t have all that fancy strapping of 5000watts I had 3500 over all at max. Probably didn’t use all of it at all Kid at my job is running 3 18”s at 3000 watts a piece basically. And I started looking into all this new fancy stuff.
Well good evening Big D Wiz love your videos I have a question if you take a 4 channel amp running into Channel mode I'm one of those channels to home low on the 2nd Channel 4 ohm load are the channel separate on what I'm trying to say if I run two homes on one channel and then two hours on another channel will that bring the app down to 1 ohm load are all channels run separately
Lol you crack me up wizard, your all like wayyyyyyy back in the day hahaha they only been out for a couple years dogg hahahah feels like a yr I got me a jp5 n I think I might buy this purple one too the finishes are sooo beautiful bro I’m not even gonna use them just gonna sit in my storage
😜👍
Thanks for doing this. I was curious how strapping worked.
From what I see, they're running in series.
Essentially, yes but each amp is operating 180 flipped polarity to the other. It’s easier to think of it as two mono amps bridged.
Awesome video Big D!!! I’ve always wondered how the power output does when the amps are strapped, and now I know.
When I bought my JP8, I purchased the 2 year warranty that covers running it at 0.5 ohms. Soooooo……. that makes me think when running speakers with impedance rise, I could run 2 of these amps strapped at 1 ohm. Hmmmmm………..
same thing I thought, I bought the purple jp23 on sale a while back. they have a 2 year/ 0.5-ohm warranty. so technically with that voltage this could rival a taramps 8k in performance. without the annoying fans, warranty, cooler looks, and about the same price. yeah, you do have to wire both amps so it would be about the same price but idk that would be my preference
With speakers most likely it would be fine. These amps are tough, if the load is too low they will go into protect
I can honestly say in 15+ years I've never actually met somebody running strapped amps in a non-competitive system. Maybe bc most ppl have subs/amps already RMS matched so when they want to go bigger it's likely they'll need another sub that can be run independently.
The one benefit of strapping that can't always be achieved with more money instead is cutting down on your X dimension in exchange for greater Y if you're limited on space for length
Hey big d wiz i just put 2 these in my cart yesterday thinking about strapping them get ojt of my head!
I'm getting ready to strap two Soundqubed 2200.2's together, do this is good info for me. 😀
You should've hooked those amps to a beefy sub and meter it. Give the people what they want lol...big bass!! Im planning to strap to audiopipe amps to an American Bass 12 XR.
He's a strapping young lad .
Minus the young part . 😂
Thanks Big D✌️
I've been running 2 jp23s v1 for about a year and a half now first on 2 skar zvx 18s in a wall build now they're strapped at 1 ohm on a zv6 12 pushing it hard daily
just thought id add to get these amps to go into protect and they tuned pack on just fine i had to run em strapped at half ohm so .25 each and they played music for a few minutes before going into protect
Can you test the Mobile avionics amps?
Because your videos I bought a jp23 love this amp ty for your videos, I don't buy any amp without a trench report from you 🤣
How does setting clipping work? Do you set the master than slave or does the master control clipping for both? Does it matter where settings are on the slave or are they all overridden anyways?
Big D, please do dyno on jp3 555 watt Amp 4,2,1 ohm stable ) thank you sir
Nice I have my 2300 rms watt Soundqubed amps strapped at 1ohms. That's .50 per amp!
I have 2 JP 23 v2s and they will be running 2 Resilient Sounds Platinum 18's. I can still use master and slave function if I'm not strapping, right? You said the controls for one amp control the other, so will I be able to use a single bass knob and not have to set the gain and crossover frequencies for the slave amp?
You need a voltage and current stabilizer so that there are no drawdowns in active power. Do you have such devices for active stabilization of direct voltage and current on sale in the USA? Or do you need to design a printed circuit board?
I haven't had a system in years, but I'm thinking about doing one just because of D4S. What an amazing value! $180? Check please.
Im feeling some kinda way bc I recently purchased a Skar skv2 1500. And it cost the same as the JP23 I see. Which in your opinion is the better amp? Should I buy another Skar and link it or should I sell it and get a JP???
Can you do this test again with the Rockford Fosgate T-2500bdCP strapped? I'm interested in the numbers you get considering the decrease in efficiency in comparison to the solo results? I just bought a second one (refurbished) and a BD sync cable looking to plan for something crazy with them when I get another T3 sub. ... @Rockfordfosgate can you help Big D Wiz make this come true?
Hi, can i use the Bridge out just for signal to a second amp ? Or i need an amp with dedicated RCA out ?
Hey big D, I've been watching your show for awhile I have a question for you? My Partners came over, one had their bass Subs at 8ohms 2000watt rms, the other partner was at 1ohm 2000 watt rms both had the same amp company but obviously the eighth ohm app was rated at more power ( but it doesn't matter because they both played their music at 2000 Watts) ,
The 8ohm system sound way better it was clean crisp punching Bass not to mention he played his music all day literally with no smell of dual coils heating up, no nothing🤷♂️
My one-ohm guy could only play his music for maybe 30 -1hour straight without it having that burnt up smell with the amps heating up to the touch, it didnt have that clean crisp bass punch it sounded muddy compared to the 8ohm🤷♂️.
I would love to see you do a test like this comparing sound quality with different ohms ....✌❤ Big D
What hz do you use to run your Dyno highs mids bass
Is it possible to do this with two different amps?
I'm sure no company recommends doing that & no controls will sync, but I think it will work with a few pieces added to spit the signal.
My qusstion is would u get the same outcome if u perfectly gain matched your 2 monoblocks and wired one amp on each voicecoil on a single subwwofer build? So is strapping the same outcome should be right? 2 amps to 1 big amp or 1 amp per voicecoil power would still be the same outcome coorrect?
Bro, off topic but the
Audio Apex CAB-M165 5 Channel Car Amplifier
Looks like an amazing bargain for $299! Review coming?
They did not provide "Whack Math" as you call it. The math is absolutely correct. At 1:20 they show 650 watts at 2 ohms at 14.4 volts, that would be 36.055 volts at the outputs. Formula for wattage 36.055volts x 36.055volts /2-Ohms=649.98 watts (650 watts). Once you "Strap" the amps you now have 72.11 Volts at the output of the 2 "Strapped" amps. 72.11 x 72.11 /2 Ohms = 2599 watts... Otherwise known as 2467 watts @ 13.79 Volts just as You showed us with your dyno test. Again back at 1:20 they show 2300 watts at 2 Ohms @ 14.4 volts. That's the part you call "whack math" but no sir, that math is absolutely correct and you demonstrated it. They show 2300 watts into 2 ohms strapped instead of 2599... why? Maybe their power supplies aren't strong enough to push against each other when strapped, maybe other reasons, the world may never know. Will you publish this post? I hope you realize your mistake, surely you know ohms law and the way to calculate wattage by now. Have a Nice Day
So let's try it this way if I take a 4 channel amp only used two channels can I run them differently for example one of those channels 2 ohm load 2nd Channel 4 ohm load is that separately or is that combined together in the amp
what's minimum THD your bench can measure? Lets say if I'm interested what power amp can do in 0.01THD or 0.005 THD ?
Could you test a Boss MC900B?
I was just wondering Big d. I have a crossfire xs-8x that’s I’m running on 12v instead of 18v. I’m actually curious to how much power I’m actually getting. If I sent you the amp could you test It and make a video?
interesting, would like to see my orion hcca 3k strapped i see 4k on music not full tilt, seems hard on the amps mayby just gain match
Some say that the Purple amp is much, much better 😁😁
Now if Down for Sound could have the bass knob the same colour as the model amp it come with. 👌
But you typically want to hide the bass remote? I’ve had other people want the colors too
Every time you run one of those brutal tests I'm just absolutely astonished and the performance and durability who those D4S amplifiers. The kind of remind me of the fosgate amplifiers in the '90s where you could just hammer the crap out of him and they would still just keep going
Do you absolutely have to run 2 power wires from the battery or can you just use a distribution block???
My mono Amps are not linkable but the way i run them i dont need too, i have two Pioneer GM-D9601 amps running at 2 ohms driving two 4ohm SVC subs each.
i would probably be better off getting a more powerful single amp, it cant be the most efficient running two separate amps.
I do only have one remote for both amps however, i bought a dual output potentiometer of the same value to replace original and put it in the housing and then added a second socket to it to connect the second amp.
summer coming up we need more sound and more budget bass :D
I wanna see some of the alibaba or ali express amps tested on here lol like the recoil dl550.4
The single JP23 was tested at .5ohm
Could a strapped pair run when wired to 1ohm?
