Tech Talk: Properly Setting Sub Amp Crossovers 

Best, and quickest, explanation of filters types and their terminology that I have heard in 15 years. Thank you immensely.

One of the best ones ive ever seen . Simple and clean

One of the greatest and quickest video with all the info I needed.

Quick and to the point. Great video

Very helpful 👍 ....made my doubts clear ...wanna see more videos on how to tune a subwoofer amp

Such a simple and straight to the point informational video!!! Thank you for making this as easy as possible

Great video great explanation. Thanks

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

Great video, made me understand the complexity of tuning.

That vocab lesson and gauge meme 10/10🔥🤝

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 RU-vid 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 👍

Nice vid. Easy explanation. Love the Mjolnir tat. Hail the Gods!

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?

OMG this video helped me my subwoofer sounds awesome now

Damn good vid!

Very Helpful!

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.

You are a GOD! Lol seriously, thank you.

Great video

Oww men thanks 🤦🏻‍♂️already buy 4 amps. were in the have you been!!! 🙌🏃‍♂️🔋

Finally a good explanation

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?

Can some of this apply to the setting for the aftermarket head unit also?

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.

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?

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

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

please make one video with how to use dd dsi 2!

And if using say a 3 way electronic crossover...what you do with the amp crossover

Put the gain where you like it... Oh thanks for the specificity 👌🏻

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??

I love his energy lol

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!

thanx 4 tips sir🔥❤

I had a clarion 3 way cross over sometime i don't hear my bass at all

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

Great Video .. Straight to the point. You bumped right through and passed it through See what I done??

Try to make a dsp Equalizer tuning video

So my 12" shallow mount mtx has a 29.61hz rating. What should my lpf settings be set to?

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

My Pioneer head unit does all of this!!

Oooh tone generator then. perfect thanks

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

Hi What if I’m using an extra crossover like a clarion? What should I do with the amp crossover? Please Thank you

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?

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

SO if i set my lpf higher but use my source's lpf at 80hz isn't it right?

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 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 ?

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?

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.

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

yeah yeah. but cannot the amplifier

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?

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.

What about systems that have crossover on stereo

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

All dd amps don’t come with a subsonic filter

Easy Piecie!. 👍

So I set my subsonic fliter at 35hz and leave my LPH at 50hz?????

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

My amplified speaker box is rated 20-200 hrs Can I do better than 80 hrz?

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

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

JBL and Pioneer mono amps don't come with subsonic filters! What should we do in that case?

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

My woofer can switch between off and full, in which position should I set that?

i dont see sub sonic on my home theatre sub.....

What about Bass eq?

Gotcha

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?

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 ))))))))))

So speakers @120hz and subwoofer @80hz .... is a good setting ?????

The earrings are a "bit", right? (please say yes)

“Gauges not required” damn there was me thinking my gauges finally had something going for them

I thought you're that beard channel guy

First comment! Thanks for the video guys!!

And not all of y’all’s amps come with subsonic I got a 1600x1 that don’t

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?

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.

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.

Oh just get a DSP and fuck dealing qith the amps wide gap frequency ranges

Do i need toilet seats in my ears too ?

You’d assume a guy who works for a company like DD would advise you to use an oscope and a Distortion Detector…

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

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?
