Basically, just turn the gain knobs (on the problematic amp only) down to their minimum and turn your head unit to about 75-80% of the way (i think that is about 32-33 on Pioneer if out of 40). Then turn the gain knob(s) up until you hear any harmonic change in the sound. Once it either distorts or sounds differnt, back off until it is back to normal.

The best thing for ground wires is for them to be attached to bare metal. So a little bit of sand paper should help you out there.

how do i reset the gain?? im going to relocate the wires to the chassis 2morrow . and the paint on the amp isnt chipped but where my ground is on the sway bar it is scratched. i appreciate the help im going to try it tomorrow.
anything else that can b the problem i will try.. thanks

It sounds like the amp could be overheating. You may want to reset your gains on that amp and see if that helps. Your grounds would be better off being fastened to part of the chassis.

Is the paint sanded off where the wires are connected?

ok i have a pioneer head unit. i have 5 1/4 speakers in front door and 6x9 speakers in rear decks. all 4 speakers are running to a pioneer 300 watt amp(4 channel). then i have a 1000 watt rockford pushin a 10 inch kicker. when i turn the volume up to around 30, it works for a few minutes and then the sound cuts out of the speakers and the sub stays on. very very little sound comes from the speakers, and they might go back on. the same thing happens if i turn up the volume and then lower it. the sound jus cuts off and you hear it very little with the sub still hitting. i am runnin a 4 gauge power wire then splittin into 2 8gauge wires for two amps. my grounds are both hooked up to my rear sway bar.
what could be the problem and how could i fix it. if any more information is neededi just ask
i appreciate any help it is an annoying problem.. thank you
