update on alternator noise over speakers

[Tim Sidders]

I have disconnected the RCA's, and the noise goes away....These are $40.00
Rockford Fosgate cables which are supposed to be very good. I guess this is
telling me that the problem lies in the RCA's, maybe if I move the remote
turn-on so it doesn't run along the RCA's this may solve my problem.....
