[QUOTE="snoopdan, post: 1756275, member: 564991"] Putting the rca loop isoloator helped a bunch, but remember I cut the sheathing on each RCA onnector near where it plugged into the back of the head unit, and ran a wire from the sheathing to the grounding / mounting screw on the center of the back of the head unit. I, as you, identified the head unit as being the main source of the noise. In my setup, I have a Audiocontrol Overdrive, and a Audiocontrol EQX that is in line between my amps (which could induce more noise) ... but that wasnt the case. What I did is I grabbed one of those $10 portable cd players from walmart and got a miniplug to RCA converter for it, so I could just plug my signal processor's (the audiocontrols) inputs into the cd player instead of the head unit.....the result? Absolutely no noise whatsoever. The **** head unit is what was at fault. Like I said, ive seen this problem with fellow team mates with similar pioneer head units, and some people dont have the problem at all.....its like a craps shoot it seems if weather you get a head unit that does it or not. Funny thing is I pop my old Sony xplode cd player from years ago in place of the new pioneer deck, and its perfectly quiet...haha.....oh well.....im throwing this Pioneer in the trash next week anyways - where all Pioneer head units belong.
