hehe, actually, me and my friend were playing around with this today, we were playing with the RCAs and grounding the white wire to the chassis of the deck, that made the sound go away. What ended up doing was taking a wire, wrapping it around the red RCA after peeling back a little of the shield that surrounds the plug and grounded that to a screw on the deck. Poof, it went away, can't explain it, but it somehow works awesome now.
