I just finished installing the door and rear deck speakers and the sub. I have 4 ga. power and ground running to a MTX 4405. The ground is bolted to a bare metal surface under the seat. The problem is, when the key is turned to acc. everything is fine, when you start the car, you get a nasty buzz sound out of the all the speakers except the sub. I changed grounds twice, once on the seatbuckle bolt and now on the floor under the seat, I sanded the metal and bolted it down. I have Monstercable RCA's with the ground on them and that is connected to a piece behind the dash. I am totally lost, any help would be much appreciated!
