I have 2 amps, one to the sub and one to the doors. Every time I hit the gas the doors squeal with the rev of the motor. I think the one amp is not grounded right. But when I hit a bump the squealing eithere goes away or gets loud as hel*. I don't know what the problem is. If it is the ground anybody got a pic of where theirs is gounded at?? Any other suggestions??

Make sure the amps are not touching metal. Put them on carpeted wood or something.

Do you have both amps ground to the same spot?
What is the RMS power for each amp, and what size ground and lead wires are you using?
Are the amps ground on the opposite side of the car from where the battery lead is run?

Factory head unit or aftermarket?

Just a couple of questions. ;)

+ make sure your rca cable aren't run with your power cable(s).

does it matter if the 2 amps are grounded at the same spot? RMS: 200 and 700. The ground is right next to the amps and the + is on the same side. Aftermarket head unit.

keep the ground and the rca's as far from the power cable as possible

the rca runs along the side and the power runs in the middle of the truck cuz I didn't have enough wire.
