speakers static and some popping
Bought a used 1997 Pontiac Grand Prix for son. it had factory speakers but had a Pioneer aftermarket stereo installed already. we were upgrading /installing new Kicker speakers for the front and back. Everything seem to work then all of a sudden static all around on every source radio, CD , or aux. it was a constant static. You could turn up and down the volume but the static was the same volume. Then about fifteen went by and we turned it on again. This time sound but the back speakers sounded like super distorted. Is there an factory amp that might be bad? There is any amp to my knowledge.
