Tuning a Car Audio System w/ Two Subwoofer Bass Amps & 4 Channel Amplifier | How To Set OSCOPE Gains

[@Bawla187]

Another great video. EXO man you need your own audio shop.

[@Minibikemike123]

He needs his own audio brand!

[@liljamesjames1884]

Exo look how far weve come together i remember watching on my inlaws cpu and you. Literally would throw stuff in to friends and family cars just to see wat it would do. man time flys!!!!

[@ravanramnath9631]

When setting the gains in this manner, the load should be connected to the output of the amplifier. The no-load voltage at the output is much higher than the voltage with load. The method used here will still yield clipped/saturated output signals to the woofers which you were initially trying to avoid. That aside, good video!

[@kransurfing]

so nice to see you still going strong, been watching you since I was 12 man haha

[@Buzzard24]

Thinking about the imbalance on the 4 channel, is it possible to have an inconstant read by alligator clip to loose grub screws? May be better off with a bare wire lead or probe tip actually clamped into the amp's terminals.

[@BrainHurricanes]

Good point. I also think it would be a better readout with a dummy load connected, or if you don't mind the noise, with the actual speakers connected. Turn up the volume until clipping. Or just listen, if you're not deaf allready lol.

[@marcmathes41]

your videos on tuning are very good. easy to understand.

[@EXOcontralto]

Glad you enjoyed, thanks for watching!!!

[@xyanide1986]

12:45 & 13:50 left/right balance setting in the head-unit?

[@savionsmith7418]

Was the balance being used?...if you forgot to flatten that that could explain the voltage difference in the 4 channel.

[@Jacobt844]

I thought the same, gotta check out what settings the people use cause it's usually whack

[@ttlylegitdood]

You should try cutting up old RCA female and male ends, strip down the insulation, separate positive and negative, and use that to connect to the RCA cables rather than the alligator clips. Its much faster and safer. I tune my system the same way with a oscilloscope, its the only true way to go, gives you more insight as to what is going on in your sound system than any other tool.

[@haze541bsn]

I was thinking the same thing instead of those alligator clips lol I have a set of "patch cables" for everything I could ever want to test to avoid using those damn clips

[@lowhertzhighspl]

QUESTION: What does it mean when on the oscilloscope at the top of every wave my amp shows a thick crinkly snow-like cap as if a mountain top covered in snow?? I'm setting my gains before clipping and it constantly shows these snow-top mountain like waves. If I were to guess, it would equate to a dirty 8,000 RMS watts but before I jump to conclusions I thought I should ask the AMP PRO (that's you!). I have screenshots of it I could email you if helpful. THANK YOU!

[@DanielRichards644]

left/right balance on the headunit maybe, for why the different output voltages on channels of the 4 channel amp?

[@NvTwist]

Does it matter if the vehicle is running or not? Should it be running and producing enough amperage to feed the amp to get max output? I ask cause if your running off the battery at 12v, set everything to gat max clean power then later while your driving and amp getting 14v+ wouldn't cranking the volume to max cause issues?

[@amorton94]

NvTwist I don't think there would be an issue. You're just sending more power and it's tuned to be clean at less power, so it will be under tuned at full power

[@NvTwist]

amorton94 I wonder because let's say the amp is dialed/tuned to & outputing 600w (voltage output measured) while @ 12v then after starting and running on alt @14v+ would the output remain at the previous voltage measurement/watts as before. I'd think the readings would be higher which means over driving speakers. I'm aware the difference wouldn't be enough to create any issues or damage the drivers. Just a thought I had and when you go to such lengths to perfect the system setup it could be worth a look or test. I'm not running my system Setup to perfection or competition but there are those that do which is why my questioning came up in my head. Maybe I'll test the theory myself one day but it's to damn hot in vegas during the summer so it'll have to wait till fall.

[@indianaoutdoors1776]

I just saw this guy at Slamology, nice system! I am pretty sure he only had one alt though but I'd love to hear after! Too bad EXO wasn't there!

[@drewbush6535]

I installed my amps and speakers had "professional " tune amps..he burnt my woofer up smelled.. crustchfield said set it to 26 volts. My scope tool said I can turn it up. Your thoughts?

[@hinesvillebass6742]

had same thing happen. my shop said he tuned it said it can go to max no clipping. bought o scope cause i dont trust anyone sure enough it clips at 16/35

[@isaiahhood236327]

Okay, one thing he isn't mentioning in these videos is even though these amps are tunned so they don't clip, you can still overpower your subwoofer/speakers. You've gotta remember these systems are designed for comps. If you're cruising around just listening to music I doubt you'll be hitting 151db. Tune to find the clipping point of the amplifier then adjust the gain so you're getting the maximum rms voltage of your subwoofer/speaker. Use ohms law. I would also install a bass knob so you don't have to mess with your preamps. Just what one guy is thinging. But since EXO doesn't respond we don't know why he tunes amps the way he does.

[@UltraCon79]

You should tin your speaker wire leads at the speaker output on the amp to have full contact with all of the conductors.

[@EXOcontralto]

The extra steps do make it all come together! Hard to convince most to take the time and do everything by the book ;)

[@derekthomasgriffin]

How’s it going brother! Been learning so much from you and your vids, thank you for your time and effort! Got a request: I’m someone who has a factory head unit, an Audiocontrol Lc2i, an Audiocontrol bass restorer, and an aftermarket amplifier. I’m sure I’m not the only one with the extra bells and whistles :) Can you please teach us where to start checking for clipping, and where to go after each step until we’re done tuning for clipping? Thanks again brother!!

[@carlosa.rivera8351]

excellent video. why did you don't use a preamp.

[@eekaj]

I remember this guy from slam. It actually sounded damn nice before you tuned it.

[@SClub7Fan]

A clipping sine wave becomes a square, not a saw (saw has WAY more harmonics). Wicked video as always, dude!

[@allrimmedout]

so did you check the voltage of the 4 channel rca's before the amp? like you said the rca's could be screwing with the voltage

[@trent1234108]

exo did you check voltage at high RCA's. didn't see you do that in video. that could be where the voltage difference is

Man this video was so fuck dope exo 5 years ago omg keep up the good work can't do with out you learned so much from you

[@xyanide1986]

To really ensure you're clean of distortion, the load certainly plays a role. The amp can either run out of voltage or current-driving capability and it'll clip.

[@b1782w]

So I'm guessing it doesn't matter the ohm load ? I mean if u set the gain is it going to be the same "clean signal" whether 4 ohm or 1 ohm?? Sorry kinda new using a tool and not eats to set amps

[@EXOcontralto]

b1782w The output will be set optimally for those different ohm loads as well. Amplifiers are always experiencing changes in impedance.

[@robertkehlerjr.8258]

you would have to take off the case bottom of the amp and find out which potentiometer controls what channel... theres secondary pots in the amp that are the fine tune for the outputs and you can match the gains so they have the same output on the main pots on the outside of the amplifier per set of channels

[@nickmik9699]

lol

[@Budaboose]

The app is to be used with a special microphone that can accurately measure the db's. Didn't you hear him say we got the SSA meter up on the dash.Your phones microphone is wimpy and can't measure accurately anything over 100 decibels. It's common sense that the phone mic is not strong enough. Haven't you ever seen a you tube video of a concert. The sound quality is always distorted because of the extreme SPL at a rock concert. It's just flapping all around while trying to record loud SPL. Perfectly fine for talking though which is what phones are really meant for, even the smart ones LoL.

why dont u need to test high on channel 3 and 4????? r u using a 0Db or -5 Db?

[@CH-py8zv]

So you are losing one tenth of a volt along that length of rca cable the further away you go from the head unit. What is the fix for this.

[@mr.raspberryjam947]

C H Thicker wire could potentially fix it but you are always going to lose a small amount of voltage no matter how thick the wire is

[@mikemcmullen4077]

Use a line driver with an adjustable gain control on it. Audio pipe has one that is also made to support multiple amps. 3 inputs 9 outputs. Max 10v out put signal you can adjust to what your amplifier max signal input is. Also recommend getting an o-scope/DMM combo on amazon. like $60 bucks.

What if your speakers are lower rms than your amplifier puts out? I just bought a 4 channel amp putting 100 watts x4 channels at 4ohms and im hooking up some mids/tweets to it rated for 40 watts. Using some maths I figured my voltage should be about 12.64, so if I used an o-scope thats what I should use?

[@axey7476]

With just 2 12's you shouldnt need an upgraded alternator, maybe try adding a farad capacitor or a deep cycle battery between the amp and cars batt.

[@facetime9156]

Keeping your battery charged will keep the load off alternator. That will keep you from upgrading and stressing it. Capacities are dangerous in my opinion. Mine didn’t work bad $40. Make sure you look at big 3. That will let you look at your engine plus you can add bigger wire ie big3. It will be easy to read about. You can check battery first if any corrosion. Oh and your grounding for subs. Multimeter will help that. Good luck plus see what others off of google have done with your car as far as upgrading

[@bumpylump9236]

@@facetime9156 1000 rms per farad it works if you get a boss cap and do the numbers. I went from playing in the 12.6 range to 13.0 and up jamming harder. It don't stop dimming much or car electrical stuff. But when the amp needs its juice its the closest power provider. This means no power lost or drop for amp.

[@gianstevens7918]

Have you seen Barevids' video on setting amplifier gains? He showed us that amplifier gains that are set without being loaded (no speaker load attached) clip as soon as you attach the ohm load. Have you thought about that? Can you respond to that?

[@EXOcontralto]

It's all dependent on multiple factors, not just the existence of a load. I've dealt with many amps that behave just fine. Would be an interest comparison video from each board to the next!

[@triniwarrior16]

Hey I'm new to all this, I've got a question. I have a amp that has a low pass and high pass switch what does that do?

[@dylans4788]

A low pass is like a crossover built into the amp, so low pass only allows the lower frequencies to only go out through the amp (if you're using the amp for subwoofers) and the high pass is for only letting higher frequencies above the bass and sub-bass frequencies go through, (if you're using your amp for mids and highs)

[@toc13boss88]

your improving car audio

[@junkyardchronicles1289]

Should have checked the balance on the radio to see if that was the issue on having more volts on some channels. I think it was a R/L issue.

[@brettus9115]

Could the voltage mismatch on the vocal amp be from the HU fade settings? Or RCA connection/impedance?

[@MeatPopsycle]

You should take a female RCA and wire it so that you can just plug any male end into it, rather than having to use the alligator clips. Am I making sense?? Kinda tough to put what I'm picturing into words.

[@hshj04]

I only have 2 15s on 1200 watts but if I came to you could you tune it?

[@DARKSEID007]

@exocontralto exactly why does he have fused + & - leads on the smaller amp or is that distribution blocks? ahh yea I see distro blocks, but guess it won't hurt for both fused. that is a first for me.... also is 40hz the recommended tone for setting or is it better for the hz your system is loudest, like my 4th uses 63hz & roughly 43 hz.

[@orfeous]

clipping and distortion i do my system with SMD DD-1 more easy to use because you can plug the RCA right into it :)

[@sidewalkcrackinmf9678]

Can you make a vid on how to tune by ear?

[@DanielRichards644]

with the subs disconnected turn the volume up to the highest setting you want to be able to turn the volume to (if running on a headunit for the 4 channels instead of a dedicated amp this will be just below the volume level that introduces distortion, on Pioneer units that go to 62 volume I find this to occur somewhere in the 50's, but high 40's, like 46-48 is usually where I stop turning up the volume just from how loud it is on those units) once you start to hear distortion in the door speakers, just below that is your max safe volume, from there start with your amp gain all the way down, reconnect the subs, turn the volume up to that loudness level you determined was just below distortion and slowly raise your gain control until you hear the subs start to distort then back it off to just below that point, basically the same thing he does here with the o-scope just use your ears to listen for it.

[@boogazincorporated]

not a bad explanation, might give that a try

[@roach_d21]

When you get a high output alternator, should you replace your factory alt with it, or add it to your factory so that you have 2 alts?

[@clinthernandez9393]

You replace it, adding it will run you into more trouble depending on what vehicle you have, considering you have to purchase custom brackets and a long belt, as well as more electrical connections

[@913los913]

Exo what if i dont have a fluke how can i tune my 4 channel.

[@talkenrain842]

Good video but when setting the amp gain i'm pretty sure it should be done with the amps under load. Setting the output just below clipping gets in the ballpark but without a load isn't really very accurate. The amps WILL clip at a lower voltage under load.

[@box420]

hey EXO I had a problem with my amp today. And I need help. I recently installed two Kicker comps that have a peak power of 600 watts and then I had an old substation kicker at which is a 10-inch only 100 watts and so I connected separate ground and power to it and then the same remote coming straight out of the other end and then something happened and it tried to pull power through the remote wire for some odd reason and melted it have any ideas why.

[@MrMaxyield]

Not enough details but it sounds like you have a bad ground on your amp(s) or head unit... May also need a relay for your remote... none the less you should fuse your remote at 5A to protect your equipment...

[@GetTrickyinHD]

I’m working on Two projects and I believe by watching your videos I may need a 4” Dayton woofer. I’ve made a box about 16” wide and 8”deep. I an using one of the small T116 boards that is 125 x 125 x125 for bass. I ended up putting two 6” and two 4” water proof with built in tweeters and a Bazooka 8” woofer in it. The speaker sounds good for what I made the box for, to be able to hear the TV over our hot tub but the bass just isn’t good enough. I’m on a tight budget and have to save all I can. I didn’t put a port in the box but was wondering if a 4” Dayton wouldn’t be better? That’s the first thing I need you advice on. The second thing is I want to put a tub style setup on my golf cart using the same board and maybe all Dayton speaker. 4”pipe isn’t as noticeable and I could use up to 4” speakers in it. Basically I want it to have good clear bass not destroyed but have enough to enjoy the sound while using it. Could you please give me suggestions on setup and the model Dayton speakers I need for each project? The end on the Bluetooth amp rms was surprisingly there but the speakers won’t so I added the two 4” speakers and wired them in series. That got them to sounding as good as you can expect but I think the 8” Bazooka is just not a quality speaker. And on the pipe just let me know how many and if the Daytons are what I need. My email address is [e-mail] thank! If you could help me out. I’d really appreciate it! I had to get the tub and cart because of my health issues! I am alone most of the time and enjoy music!

[@nismofreak33]

you can actually set it by eye haha. turn the SS all the way up and play music that you know goes well bellow your port frequency. Play it at maximum safe volume and slowly turn the SS filter down, keeping an eye on the woofer. Stop when your subwoofer is still moving nicely but not excessive and uncontrollably, essentially not flopping around like a bag of dicks.

[@borealis370]

it is. Choose a selected frequency for subsonic, for example 25hz. Play a tone at 25hz. Turn the subsonic knob. Look for a significant drop the AC volt on the DMM/Scope. Then you know where you're at. Instead of playing ear-guessing-games.
