have you tried switching your RCAs around, just to see if the sound in introduced by a certain set of RCAs?

Where is your power wire ran? Is it right along side your RCAs? Try moving them away from each of if so?
Check your grounds too, I always try and keep my ground wire as short as possible.

Next as plcrides said, if you're using really cheap RCAs try getting some better ones. I like the ones at knukoncepts, better quality and pretty affordable.
