Subwoofer level on headunit gone!

PerfaLock · 05-12-2009, 05:59 PM

I just took my car in to change the transmission since the old one was blown...and i just got my car back and when i checked out the head unit, it seemed as if it reseted and there is no subwoofer adjusting level anymore. i hooked up my amp to see if it would help but it didnt. Do i need to wire my subs? or is there a way to make it re-appear again>? only my amplifier is hooked up, no subs.

Should have a sub level control if there are no subs hooked up. They might have shorted something out...Nothing should be erased from the headunit.....what is the make and model of the HU?

oh i got it:P

and one more question, i have a bandpass box, and 2 subs in them. The magnets of the subs are right down touching the other end of the box,,..do i need a bigger box, and does this affect the air from moving?

it would be good to have at least 1.5 inches all around the sub.....must have been a custom made jobby.
