Increasing gain past 3/4 not louder, but increasing HU volume is?

[timma100 10+ year member]

Now this is on the gain knob, but beyond 3/4 on the knob the subs don't get any louder. So I figured okay I'm clipping them, fine I just wont go past 3/4. But, even at 3/4 on the knob even one tick higher on the volume produces a substantial gain in sub-woofer output. I haven't found the point where the increased volume doesn't produce increased sub-woofer output because frankly its to **** loud lol. So could someone shed some light on whats going on?

Short answer? You're retarded.

Your gain should never even be at 3/4ths dude, 2v's is at like 2oclock not 3. Get a DMM, multiply the rms of YOUR AMP times how many ohms ure sub is, get the square root of that number. Get a 50Hz test tone, play then tone and turn your volume knob to MAX listening volume. Like a number you never go past, mine is set for the max volume of my HU. Now with the test tone playing, turn your gain till the voltage is the number you got early by RMS x impedance then square root.

That is how loud ure sub is, period. You can only turn it down from there. If its not loud enough for you get a better sub or box.

hmmmmm touche, but seriously, gain is a multiplier based off of the RCA voltage, perfect example is why a HU with 8V preouts takes less gain to reach the full potential of the amp then a HU with 2V preouts.. But explain why half gain is a loud as full gain. But half gain with a volume increase causes more output from the amp. Is there only a certain % the amp can multiply the RCA voltage? ":|

I did, the max volume I listen to was 20 on my HU, but even at full gain the amp wouldn't produce even rated power (1500) but with higher preout voltage settings it could

when u turn ur volume up ur increasing the voltage put out from the head unit

how high of a volume level is your head unit capable of? I know it dosnt just go to 20, i had to change mine earlyer today so it would sound cleaner on my AQ

Your max volume sound be where your HU starts to distort, i have my alpine set for max cuz i think it still louds fine at max. You may have to back your gains down a bit on your high amp(if you have one) but it makes the transitions smoother
