Alrighty, as weird of a setup as this may sound, humor me. I built a home component box for my empeg, and now want to run the reciever out through the AUX in of the empeg. So it's like this:

Rio Reciever -> empeg AUX in (on sled) -> Kenwood stereo reciever.

It sounds like crap. There's clipping all over the place that wasn't there when the reciever was going straight into the Kenwood. No matter what i do with the volumes on all of the units, the noise doesn't go away. The Volume on the Rio Reciever is irrelevent as it has no effect on the RCA outs, the empeg is at 0db like it should be, and i just can't figure out where the clipping/static is coming from. Any ideas?
