Very simple easy to understand tutorial for setting the amp gain. Now my problem is this. I used a 50 Hz test tone to set my subwoofer amp gain to 31.62 volts ac with head unit at 75% volume. Amp is similar to the video, RF prime 500 watt rms monoblock, pushing a 500 rms 12” d4 sub wired parallel at 2 ohms. but now I have almost no bass? What am I doing wrong? I believe the issue is the test tone vs playing music where the rca signal voltage varies and is generally much lower on average vs the max signal voltage using the test tone. That’s my guess anyway.

Me useing the exact amp he said not to use

I have a question for you. I always run my head unit bass setting at negative 4, so that my dash and door speakers don't get too much bass. Those all run off the power of the head unit, no external amplifier. Even at negative 4, the door speakers are plenty loud and have plenty of bass. When I set the input gain on my subwoofer amp, would I want to leave the head unit's bass setting at negative 4, being that's how I always run it? Everything I've read says that you want to set everything to "flat", which doesn't make sense to me if that's not how it's normally ran.

@DIYAudioGuy

3 жыл бұрын

You have to set everything flat to get an accurate reading, and a lot of times people will turn on their bass boost or crank their bass up causing clipping and distortion. If you're trying to shape the sound it's always better to cut instead of boost. Since you are cutting you're probably not going to do any damage. but you're not going to get the best possible sound either. If your head unit has a crossover then you can use the crossover to pull the bass out of your door and dash speakers. In the end always remember that it's your gear and you can set it up anyway that you like.

Every 'pro' audio guy I have ever talked to has these 'hard limits' like you just mentioned (3:13) but I firmly believe it is 100% because of how you guys learned to do stereo stuff. Everything I learned was from practical application or self taught and I'll admit I have blown some equipment, but the limits you guys mention are hilarious and the things you think will happen if you go above/beyond those limits are wholly comical. 99.9% of the time, unless you have wired something very, very wrong or have gone hilariously above the limit (on purpose a huge majority of the time), you're probably just going to get protection mode constantly, distorted sound, or overheat your equipment over and over. Unless whatever you are using is old or was beat to crap/put over it's limits consistently for weeks or months, you're more then likely ok to prod those limits with trial and error.

You typically have a separate gain control for front and rear, set them both either based on the power rating of the amp or the speakers, whichever is smaller. Another trick, if you want to emphasize the front stage you can reduce the gain on the rear channels.

Actually no, you want to hit maximum voltage with the bass boost set where you plan to use it. If you plan on adding some boost to certain music, turn it on to the highest setting, set your gain using this method, then turn the boost back down, now you know you can add some boost without clipping. It’s worth noting that if you use boost on your head unit, the max volume you can set it to may be lower. Instead of 75% volume you may be limited to 65% volume. You won’t know actual volume until you use an oscilloscope.

Thank you for this very informative walkthrough. However I have some questions. I connect my Note 10+ to a USB-C to 3.5mm adapter, then connect it to the head unit via 3.5mm AUX. With this configuration my audio is about half the volume at the same number on the head unit as playing from another source such as FM or CD. I have a Pioneer DEH-X5600HD head unit with a Pioneer GM-A5702 1000w 2 channel bridgeable amp rated for 150w x2 @ 4 ohms connected to 2 Rockford Fosgate P210S4's in a separate chamber 1.25ft3 each chamber sealed box. On an amp dyno this amp is supposedly capable of closer to 200w rms in this configuration. Considering the source volume is low (even with source level adjustment at 4 which is max on the head unit) I usually play with my volume at 57/62 listening to loud music. If I push higher than 57 my door speakers distort a bit. My system sounds great but I haven't fine tuned the gain other than by ear so far, nor have I connected my DMM to the amp except to test power input voltage and ground voltage and resistance. My input voltage is 13.8v (ground is the same with 0.03ohm resistance at amp ground and 2 different battery grounds in the engine bay) Will I get different results by using your method with the head unit at this volume? And should I try to aim for the "rated" 150w rms @ 4ohm (24.5v speaker output) or could I aim for, say, 175w RMS at this volume and should I still lower my volume to 46? I almost never use another source to listen to music in my vehicle. Any help would be greatly appreciated, and thank you again for uploading this video. Other possibly relevant information: my LPF is at 125hz, bass boost is at +6db (yeah I know, give me hell if you want but I don't hear any distortion of any kind at any volume with my ear both right next to the subs and further away, but should I eliminate it?) No bass boost on head unit, loudness on low (my door speakers are halfway decent 5x7 factory speakers powered by head unit and without it I have trouble hearing some treble listening to heavy metal/prog such as Dream Theater and Periphery) head unit HPF @ 80hz/24db slope.

You can check the preout voltage of the head unit through the rcas Set multimeter to ac Play a 40hz tone with the rcas unplugged volume max(whatever it is for you probably 3/4 like he said in the video) Probe the male end with positive and the shielding with negative Boom preout voltage, look online to figure out how many v of clean preout yours is and match from there turning the volume up or down if needed

For those fine adjustment knobs drill a hole in a ruler big enough to jam the screwdriver in. Then you have an adjuster with a wider arc and you can hit those mv numbers.

Clever trick.

I adjusted the voltage to 17 because my amp's speaker output is 75 RMS per channel running at 4 ohms at 75% volume with an 1000 htz tone and i burnt my speaker coils because my speakers were only 25 RMS at 4 ohms.

If your amp puts out more power than your speakers can handle then you have to turn the gain down.

Thank you for this video! Question, I have a 4 channel Amp with an RMS rating of 100 watts per channel at 4 Ohms. I'm connecting each speaker to its own channel so 4 speakers total. According to your calculations, target voltage should be 20. When testing the voltage, should 20 volts be tested on each channel (all 4)?

Well a 4 channel only has 2 gain dials, 1/2 and 3/4 channels. You put the meter on chan 1+ and chan 2- and move dial till 20.0v. Repeat for other as well, chan 3+ and chan 4-. (Correct me if im wrong)

@NathanC-YT

Also I tried to do channel 1+ and -. And 20v wasnt even reading no matter where the dial was. Like for ex, at the lowest it read 1v and at the highest it read 15v. Obviously thats not the right numbers but you get the point. Thats why i say chan 1+ and chan 2-

That is correct, but you only need to test one channel on the front and one on the year since most amps don't have gain controls for left and right, just front and back.

Thank you, this is what I did and speakers now sound to their potential! I always relied on my clip indicator on the remote but this method is so much better!

This is a good rudimentary way to set gain without DD-1 or O scope. The only issue i see is you don't account for attenuation when running signal via Bluetooth. Most people run their phone volume to max when running BT and that can dirty your signal for sure.

I might also add. I like how you recommend the kicker audio files for test tones. I'd rather point someone that route than to play a random tone generator. The files from kicker are setup with different recording levels 0db, -5db and -10db to help tailor your gain matching even further. Again in addressing attenuation I've always downloaded these files to either a CD or zip drive. You know 100% your signal is super clean that way. I do have a future video idea if you haven't done one yet. A full front to back gain matching. I.e. from the source unit to a DSP, EQ, ect. Showingthe importance of adjusting your gain from the source unit at every piece of gear in the line and ultimately at your amp. Great videos as always and your edit is coming along nicely btw. Keep up the great work.

Thanks

Hi great video, have a question, my amp is pushing 140 x4 watts RMS at 4 ohms amd speaker can hold up to 250 watts RMS at 4 ohms do I go by the lower wattage to get the volts so in my case is 140 x 4 then the square root

@DIYAudioGuy

3 жыл бұрын

Yep, use the lower of the two that way you don't distort the amp or overpower the speakers.

I have a question. What settings do I put my head unit on as far as bass / treble / mid before I set the gain with the multimeter? Also does this mean that I can't use bass boost on the amplifier itself? Thank you and great video as well!!!

@DIYAudioGuy

Set everything flat, I do not recommend using bass boost. If you can turn up the boost without clipping then you could have just turned the gain up instead.

I was looking at Alpine S-A60M 600W RMS amp, it was measured at 14.4 volts and 1% THD. That's not lying about it I agree that.

Good day can you help me adjust my crossover which has a built-in line driver if 5v to match my mids and sub amp and what can I use if I don't have a DD1 available... Can a multimeter be used...?

Ok so this video has helped me a lot but I’m not doing 4 ohm or 2ohm setup with my sundown SALT 4k rms amp. On the dyno it’s doing 5-6k watts and I’ll be running the amp at .5ohm final load. So since the amp says it’s 4k but on a dyno it puts out 6k what voltage should I use to set my gain on the amp then? 🥴 I’m trying to learn day by day! Again great video and subbed!

Good day Audio Guy. Firstly great job on your videos. If I am to find the voltage requirements for setting my amp gains and my Audio Control amp is 6x125 @ 4ohm OR 6x200 @ 2 ohms, what am I to set my gain to? The 6x125 @ 4 ohms which works out to 27.38 volts OR 6x200 @ 2 ohms which works out to 34.64 volts. Just to let you know I am using the amp in a 4 ohm load. Thanks and regards, Randy in Trinidad and Tobago in the Caribbean

@DIYAudioGuy

If you are running it at 4 ohms then use 4 ohms. Each individual channel will be 125 watts, so each channel will put out around 22 or 23 volts.

@@DIYAudioGuy thanks much. I appreciate the advise.

You can use a DMM to find your head unit clipping by figuring out what your preouts voltage is from the manufacturer and then use a 0db 50hz test tone,turn the head unit volume all the way up as well as the subwoofer volume on the head unit,then run your test tone and attach the ground of the dmm to the outer pins on the rca and the positive to the center pin on the rca,say your preouts are 2 volt preouts. The dmm should read around 2.8 volts not the dmm,turn the volume knob on the receiver down till it hits the target 2 volts 😎

Does input voltage to the amplifier matter? I am running an Exile Javelin and 15.4 on my boat. I set my gains per your instructions (really well done btw) with the boat off, where my dash was reading 12.6V. When my boat is running the dash reads somewhere in the mid 13s for voltage. Do I need to consider this when setting my gains, or does the amp or boat adjust for this change in voltage?

@DIYAudioGuy

For setting gains it is not terribly important. But it will make a difference in your actual power output. When voltage drops you will clip earlier and make less power. So you will make less power with the motor off. The bigger concern is draining the batteries and getting stranded on the water.

Hiya, great video. I did the same steps as in the video, but I'm only getting 1.63v from the speaker terminals when the gain is at its max. Any suggestions as to why.

You probably need to turn the head unit up a little bit. The 75% rule is usually the problem.

@@DIYAudioGuy I wasnt expecting an answer so quickly... thank you very very much. Lemme get this straight. My amp will produce 415watts at 2ohms bridged to the rear channels. The math would be the "square root of(415 x 2)" Which equals 28.08 volts at 75% volume

@DIYAudioGuy

2 жыл бұрын

That's what I got. Just make sure that your amp can handle a two ohm load when it is bridged.

Great explanation! While adjusting the gain can I use the bass boost with it?because without bass boost need to go higher on gain to hit the targeted voltage and after if I'm turning up the bass boost the volts are too high so I think if I adjust the gain along with bass boost to hit the targeted volt that could be fine?

@DIYAudioGuy

3 жыл бұрын

Avoid the bass boost, if you can't hit the target voltage then you might need to turn your head unit up a little bit. If you've got the gain all the way up and you're not hitting the target voltage then you're probably clipping. The weak point in this method is setting the head unit at 75% volume. Doing so assumes that 75% is as high as you can go without clipping, and without actually testing the head unit for clipping you can't know. If all you have is a multimeter you can check the voltage on RCA's. If there are 4-volt RCAs and you're getting slightly less than 4 volts then you should be good, but if you're getting four and a half volts you're probably clipping. Hope that helps.
