Sounds like a grounding problem to me too Jay. Anyone would be guessing if they told you a location. I would start at the easiest location to access and move on from there.

 

alrite..thanks for the help...i will be rite into it

Either grounding or RCAs....

RCAs do go "bad", but its probably the ground. Its not the head (probably) because its in a harness and thats the way it always was. The amp ground might have come loose, or whatever, so move it, and see what happens. If not, it may very well be the RCAs. (Ive had RCAs go bad)

 

hey...u gona be in the tech day...if u do..maybe u can help me to locate the problem
