Hi I used the voltage tech( square root of rms x ohms) and got 28.28 so i put my head deck at 3/4's with a 50 hz test tone and when turning the level up all the way on the amp only went up to 12 VAC. I have a bass **** in the front of the car and as I increased that the voltage went up.So what I did was put the **** all the way up and then adjusted the amp level input to 28.28 volts I then did the subsonic, crossover and and its sounds insane....only thing is i have to keep my bass **** down at 9/10 before it start going way to much...so did I set this up right?
