Damn, that's a crazy ground on that head unit. No it's a kenwood. I tried all different variations of RCA's. My power wire is run by itself on the left side of the car everything else is on the right. It may be something with my head unit (RCA outs front/rear/sub), I'm not sure. If I only use two sets of RCA's it's fine, but as soon as I plug that third set into the unit the noise comes back. I ended up going to radio shack and buying two Y splitters just using the front RCA's so I can patch them to the rear speakers on the amp. It got rid of the whine. I bet if I grounded the RCA's on the back of the head unit like that pic it would probably go away. Thanks for the input fellas.
