Alternator noise, how high do you have your gain set? And re-check your ground, it should not move and the area should be stripped of paint. Make sure your conections at the amp are secure. Check back after that.

the deck has 4 volt outs so gains are as low as they go, grounds are8-10" different for each amp to the body

the problem is with the deck when i wiggle the power harness in the back the noise stops,gets louder, softer

Ditto on what Rob said. Thank you for again proving his point.

My ex once told me I have a perfect face for radio.
