Best, and quickest, explanation of filters types and their terminology that I have heard in 15 years. Thank you immensely.
One of the greatest and quickest video with all the info I needed.
One of the best ones ive ever seen . Simple and clean
Such a simple and straight to the point informational video!!! Thank you for making this as easy as possible
Quick and to the point. Great video
Very helpful 👍 ....made my doubts clear ...wanna see more videos on how to tune a subwoofer amp
Great video great explanation. Thanks
That vocab lesson and gauge meme 10/10🔥🤝
Nice vid. Easy explanation. Love the Mjolnir tat. Hail the Gods!
Great video, made me understand the complexity of tuning.
Awesome. This helped me tune my new system. I am still getting used to the sub kicks instead of a vibration from the original audio of my car xD
Finally a good explanation
I enjoyed the "keep it simple stupid" tone throughout the video. I have watched a ton of videos and tried to learn the most I am able too from CZcams in the past 3 years all related to car audio. At a certain point someone like me could over think some aspects of tuning. Keep it simple stupid. And definitely trust your ears. Great video 👍
The gain should be tuned with a multimeter. It’s easy. The square root of your total wattage multiplied by ohms.
Example: 1500W x 1ohm=1500. Square root of 1500 is 38.72. Hookup multimeter, turn your head unit to clipping(or 80%of max volume if you don’t know). Gradually increase gain until you meet the number(this case 38.72).
If you don’t know the square root. Simply type “square root of _____” into google and you’ll get your answer.
Boom
Yup, just make sure youre using the actual wattage and not the claims on the box. It should be set with an oscilloscope though.
or get a SMD DD1 MAKE LIFE EASY
@@a.melburnspeaker wire positive, the wire you'll attach to the positive
@@michael6692my amps clip before the dd1 detects it, so I just use my amps clip light.
Very Helpful!
Great video
OMG this video helped me my subwoofer sounds awesome now
What did you set your lph and subsonic at?
Damn good vid!
You are a GOD! Lol seriously, thank you.
I love his energy lol
This is a good video!! but I think you guys are missing a video with electrical recomendation for DD subs amps, I hope you consider the request.
Great video man! I have an alpine m500 the only knobs i have are gain, bass eq and lp filter. Just to be safe, keep the bass eq down?
Great Video .. Straight to the point. You bumped right through and passed it through
See what I done??
I heard that with 8" subs you can go higher than the standard 80HZ on the low pass filter. From a guy on here that owned a shop lol. But, this guy seems more professional so Im gonna run out and lower my LPF
Oww men thanks 🤦🏻♂️already buy 4 amps. were in the have you been!!! 🙌🏃♂️🔋
What
thanx 4 tips sir🔥❤
Thank you for watching!
sir this sub amp. seting sutable for poineer d4 woofers??
Put the gain where you like it...
Oh thanks for the specificity 👌🏻
Can some of this apply to the setting for the aftermarket head unit also?
Try to make a dsp Equalizer tuning video
please make one video with how to use dd dsi 2!
My Pioneer head unit does all of this!!
same current mine is set at 80 wit a -12 Db
On my CXA1200.1 I have a few knobs not like what you said in the video. For my 4-channel yeah but I have a gain, freq bass boost and crossover bass boost. Witch one should be higher and witchbonce should he lover?
Oooh tone generator then. perfect thanks
And if using say a 3 way electronic crossover...what you do with the amp crossover
Hello, I plan to buy an ACEIRMC 200W Pure Bass Subwoofer Crossover Second-Order Crossover Frequency Distributor Divider 2 Way Speaker Audio Crossover Filter
to combine it with an Aiyima A3001 TPA3255 sub amplifier that has a frequency filter but together with this it would surely give a spectacular pure bass?
What should you set your HIGH CROSSOVER and LOW CROSSOVER on a single two ch Amp being used to push subs????
Specifically soundstream tarantula 6500.2
I prefer DMM method to set my gains as I'm damn sure that ma maps arent clipping! Also some amps out there dont even have subsonic filters! Mine have but I dont use it as I enjoy decaf low bass!
Easy Piecie!. 👍
Honestly best informing to the point quick video of f****** knowledge excuse my language that I've ever seen f****** love it dude seriously out of all the videos I've watched from all the people you are the f****** best dude f*** yeah that's how to do it
I have a dmf1600 that don’t have a subsonic filter plus I can’t get the bass knob to work I’ve tried three different ones
VERY INFORMATIVE VIDEO"HUMOROUS TOO" I installed a component speaker system some years back; I lost one of the passive 2-way crossovers to "water leaking" so I ordered a new complete component speaker system from ORION- I have the head unit set up to play thru the JBL 601 2 CHANNEL CLASS D AMP; I ran new wires from the speakers to the crossovers; I have audio only on the left side- "NOTHING "NADA" on the right side I have checked the connections several times and it appears to be good; I tested the crossover positive terminals with my test light -strange I have audio on the left side "BUT A WEAK DIM LIGHT ON THE TESTER-THE "RIGHT SIDE HAS A VERY BRIGHT LIGHT ON THE TESTER- "BUT NO SOUND" I also have ZERO LIGHT" WHEN I TOUCH THE TWEETER POSITIVE TERMINAL?? I AM LOST!! ANY IDEAS AND FEEDBACK APPRECIATED; PATRICK.P SPEAKERS TEST GOOD FOR POLARITY??
You say to set your gain before your filters.
Should we go back and re-set our gain now that we have optimized our filters?
Would that be unnecessary and more of a 'squeeze every last drop'move
SO if i set my lpf higher but use my source's lpf at 80hz isn't it right?
Gotcha
Hope this question gets seen. I have a full range running my subs. Signal is coming from stock sub, so already crossed over before amp. I have the concept of the LPF, but what should I have my HPF at since its on a sub?

Hi
What if I’m using an extra crossover like a clarion? What should I do with the amp crossover?
Please
Thank you
If the clarion is what I think your talking about, It's not a crossover. The clarion is a equalizer. Crossovers and EQ aren't the same.
I had a clarion 3 way cross over sometime i don't hear my bass at all
So my 12" shallow mount mtx has a 29.61hz rating. What should my lpf settings be set to?
The 29.61 hz your referring to is probably the fs of the sub. Which is what you use to help build a box specific for that sub. Almost every subwoofer should be set to 80-100hz. Your subwoofers should have a frequency response specification in the information that came with it. Probably somewhere between 30hz-300hz
if you have one, please use a multimeter. it will allow you to accurately set these parameters and setting the gain by ear or "where you like it" is just plain dumb. there are videos online on how to set everything with the multimeter.
When it comes to subs, u can find clipping points by ear very easily and reliably. But your 4 ch. I wouldn't recommend by ear. Always use multimeter on your 4ch. Since you have it out you might as well use it for the sub amp too.
Like there's a right way and a wrong way to set gains by ear. The right way, is to play test tones and find every clipping point. The wrong way is to play music and use the gain as a volume knob. But having a multimeter is the most helpful tool you can have.
Ive learned ya can have every tool in the world and if you dont set your head unit correctly before you try to set your amps you are just pissing in the wind.why is it every video people make they never say a damn word about the head unit.😂
I have a question so I have my radio mostly tuned for my subwoofers but I wanted to ask some questions when I turn my amp off my door speakers like to sound distorted when I turn them up because I have my radio bass bossed. So I’ve been researching and for equalizers so with that I can most likely be able to tune my radio to my door speakers and the eq for my subs right ? If I wanted to then add tweeters can I put them on the same eq even tho im not going to want the settings the same as my subs? With just having the tweeters for just highs and subs for just Lows and then door speakers ran off radio for mids

Doesn't explain a aftermarket head unit. So do you adjust your head unit hpf and lpf or set it to through and leave amps alone or visa versa?
I think its common sense personally. I would adjust the amp to 85-90hz then fine tune it to 80hz with the headunit. Then if either one filter stuffs up or resets you still have a safeguard.
I set My pioneer head unit lowpass for the sub to 80 and used the highpass on my taramps md5k and set it to around 20 my box is tuned to 30 hertz! Did I do this right?
Maybe
I have a Rockford Fosgate P3002 . Only knobs it has are Gain & Freq(hz) & Crossover switch : LP/AP/HP. I only play rap genre music so can I set it to LP , 80hz and gain to 3/4 of the way ?
Maybe
Hey sorry new to all this so if I’m runne a 4 channel do I make the LPF,HPF OF front and rear speaker levels the same example if I make front say at 70 hertz do I do rear the same
yes
if im set a low pass filter around 175hz that mean my amp is always or only produce a frequency 175hz and below ? right ? my mono low pass setting is start from 50 - 200hz and my sub rated frequency response is 25 - 175hz, sorry im beginner, my monoblock dont have a subsonic filter and only have the low pass filter
no all of that is a bit complex long story short almost any sub should be around 80-100hz.. and the rating for the sub is usually the FS to help with installing it in correct box etc...
Thank you for that I saw a video of the other day where the guy was talking about putting your low pass at what your box could handle which mine could handle 32 and he said double it so my dumbass put it on 60 and I started smelling my Subs
What if I set my radio xover to 80, 6 way active xover to 75, and my amp’s xover to 70? All highpass on 6.5’s.
Hello Brady, please submit your question through our website so that a tech can better assist you with your question: ddaudio.com/contact/
All dd amps don’t come with a subsonic filter
What about systems that have crossover on stereo
Most of the time you go into the settings for crossover and do it the same, set both “slopes” to -24hz
THANK YOU,, THANK YOU ,,THANK YOU ,,,, NO BULL ABOUT WHAT I HAVE IN THE STORE TRYING TO SELL THINGS ,, NO BULL ABOUT MATHS GRAPHS .... NO BULL ABOUT WHAT F,,,,,,,,IN AMP I HAVE ,,GOD YOU KNOBS ,, ((((((((((( WELL DONE BUD TO THE POINT WELL TOLD ))))))))))
I have a Sony head unit In the Subwoofers settings it has LPF IT GOES FROM 80 to 120....And I can't shut it off....So how do I balance this out with my sub amp LPF
Please submit your question through a website so that a tech can better assist you: ddaudio.com/contact/
Dont shut it off. Just set the amp to 80z. Set the radio LPF to whatever you want. You said it has 80-120hz. 80-120hz is well within range for a subwoofer. The radio LPF is the master settings and will over ride the amp settings. If your radio gets messed with the amp settings will act like a safety
What about this formula that out there take what your sub box is tune to like my is 32hz ÷2=16÷2=8 then take that number subtract it from what you box is tuned to 32hz -8=24hz this what you set your subsonic filter to now is this correct or false & where would you find where 24hz is on the amp I have a skar skv2 2500.1 please reply thank you?
Maybe
Its a 3/4 octave below tuning. So port tuning x .75 gives subsonic frequency to set too. Below that can cause loading issues and damage the sub. Nobody plays bass from a sub over 60hz, setting at 80hz is nonsense, 60-70hz is somewhat decent to give you overlay for when midbass drivers pick up.
You can find 24hz on your amp crossover with a smd cc1. What this video and this silentjustin dude in comments is sayin applies more to sealed enclosures. Not so much with ported.
yeah yeah. but cannot the amplifier
My amplified speaker box is rated 20-200 hrs
Can I do better than 80 hrz?
60
First comment! Thanks for the video guys!!
Top mais tem que usa entrada ociloscopio
Thank you for watching!
So I set my subsonic fliter at 35hz and leave my LPH at 50hz?????

i dont see sub sonic on my home theatre sub.....
Who’s got the hook up on doing a recone on subwoofers Can get the parts to do it my self for 70 bucks and that other company wants 250 to do the job
Subsonic means filtering out inaudible frequencies, not audible ones. That's why you filter them, you can't hear them anyway, so why waste excursion or power on them?
With my taramp HD3000 I'm getting bass from the hpf and voice from the lpf. I have the gain and HPF all the way to the right with LPF and bass boost to the left. I just don't feel like I'm getting clean bass from the amp
Sounds like you have your HPF switch off and your LPF switch on full. Sounds like you have your gain set to max and your HPF set to its highest cut off. Your not going to get any good bass with the gain all the way up. Hit me up if you still need help. I'll do my best to help
@@Silentjustin06 I'm about 2 o'clock on the gain now sounds better and I can turn my volume pass half way now . My bluetooth source level volume on the head unit was up and was causing distortion and clipping I have to do the big3 upgrade next
@@coolazznicca yeah that's sounds like it's a bit high still. Most of the time it will be somewhere between 8-12 o'clock. Its good you can go past half volume now. Say your volume max is 40. Your radio probably distorts about 35. I'd turn your amp settings all the way down. Bluetooth to Zero and turn the volume up 75% of the max your radio has. Slowly turn your gain up until it sounds like its distorting. Then back it down until it sounds good again. I would do highs first if you have a amp on them. HPF set to 150-200hz should be a safe crossover. Then do the same with your subwoofers. LPF should be at 80-100hz. The goal is to match the amp volume(gain) to the radio.
Thanks for the info
@@Silentjustin06 how would I go about setting amp ? On mines I’m still a lil confused should I set the volume to half way or above half way ? I want more boom boom and deeper bass at lower volume to half volume
JBL and Pioneer mono amps don't come with subsonic filters! What should we do in that case?
Don’t worry about mine doesn’t have it either . It’s just a nice feature but not necessarily important
“Gauges not required” damn there was me thinking my gauges finally had something going for them
What about Bass eq?
dont touch it all you would be doing is clipping the signal, turn it all the way off.
When I turn mine all the way down, they are bearly moving. Subs are 2 x 12" 800W RMS each and amp is 1750W RMS
@@metallboy25 what kind of amp?
@@metallboy25 do you have a epicenter?
@@rudyhernandez2925 Its a cheap Rockville dB 16 amp rated at 2000w rms at 2ohms. But on amp dyno's it does 1750w rms which for the price is still good, thts why I bought it. I dont expect it to work for 10 years though. :D
My woofer can switch between off and full, in which position should I set that?
Your woofer can switch between off and full? Are you talking about the LPF switch on the amp or something on your radio settings? Hit me back and I'll help you the best I can. I need more information from you tho 👍
@@Silentjustin06 when I put it to off position only the bass is coming out, and in full position music also came along
@@Silentjustin06 it's an inbuilt amp subwoofer fitted in my car, frequency range can be set within a range of 40-200 hz
@@seenathbeevip7572 oh ok, makes more sense now. So it's one of those all in one subwoofer and box with a amp built in it. I would go with off. OFF position is for just bass with no music. FULL is (full range audio) that's why you get music. I'm not understanding why they would have the option of FULL or OFF. Subwoofers shouldn't have music come through the speaker. Can you tell me what model system you have? So I can look it up and know more about it

Great video. "Trust Your Ears" cannot be stressed enough. You can get detailed and use a microphone, but I bet you will find it may NOT sound quite as good as the settings you choose using your ears, or change the crossover setting on your amp much at all. Regarding the low pass filter at 80 HZ. That's too low if you wish to get a good bass drum sound as bass drums have frequencies generally 100-150 HZ. I would recommend something around 120 HZ if your subwoofer can handle that frequency. When purchasing a sub, finding one capable of 200 - 250 HZ is highly desirable if you wish for your subwoofer to be more "musical" in nature. That means you need to have an amplifier capable of a LPF in that same 200-250 HZ range. This will give you a tight hitting subwoofer without the muddy ooze found in so many other people's subwoofers. It's good to have a speaker driver capable of playing a higher frequency even if you do not plan on using that speaker at its top frequency. So getting a sub that can go to 250 HZ, but setting the low pass filter at say 120 HZ means you are not taxing the speaker. You are playing it right in the middle of its capabilities, the "sweet spot" so to say. This is also true for tweeters. Buying tweeters with a top frequency above 20,000 KHZ like 25,000-30,000 KHZ means that you will not experience distortion because again you are not pushing the speaker at its top capability. It's when a speaker is pushed to its limit that you end up with distortion. In all audio, it is nice to give yourself some room, or excess capability with your speakers, and then only use 70-80% of that capability for a better all around sound in your system, as well as longevity of the speakers. Theoretically speaking. lol. (but honestly, no BS). PS you should for the most part when purchasing a subwoofer to find one capable of below 40 HZ if listening to electronic EDM music for the best experience.
And not all of y’all’s amps come with subsonic I got a 1600x1 that don’t
80Hz! subs aren’t meant for mid bass! well I set my subs crossover to 887Hz now my sub is much better so my sub must be meant for midrange
The earrings are a "bit", right? (please say yes)
On a Subsonic Filter 20hz - 50hz
What would it be at 12:00 position? 35hz?
20+50=70hz
70/2= 35hz
Thanks for anybody that can’t help me figure it out..
Also, LPF 20hz - 200hz
Half way would be 110hz and 9:00 position being 55hz?
So speakers @120hz and subwoofer @80hz .... is a good setting ?????
Well, do you like the way it sounds?
The amps are for sale, if you buy the amplifier suddenly has been broken down, and want to repair, they will not serve you, and say that better buy a new one.
You’d assume a guy who works for a company like DD would advise you to use an oscope and a Distortion Detector…
It's not rocket science 🤷♂️
You as a customer dealing with audio should already know that. They have videos for beginners and first timers
Do i need toilet seats in my ears too ?
Oh just get a DSP and fuck dealing qith the amps wide gap frequency ranges
your old soundqubed persona was better... I wish you guys didn't water down everything on that side of the company like you did...
this is for cars?........ thumbs down
I learned nothing.
So what’s pass through?
