Ok, for the second day now I've spent upwards of 4 hours working on this mess. This time I've ripped absolutely everything out and rewired it all, making sure the audio cables are coming to/from the amps completely seperated from the power leads.

I've isolated the problem down to the empeg (or my CD player) whichever is hooked up. The empeg itself I think is buggy and I get some VERY nasty feedback whenever it is connected up. This is a hardware flaw I think, and I'm going to send it off tomorrow to hopefully remedy the situation. I've been experimenting with my CD player, though, which also has pre-amp line outs.

Anyway, here is what the situation is. With no RCA jacks going to the amp, with the whole system powered up, I have no feedback, no alternator whine. If I hook the RCA jacks up, I get output from the stereo as well as alternator whine. So basically I'm assuming this means that the OUTPUT from the stereo is where it is picking up the feedback somehow.

What my question now is, what would cause this behavior in a stereo? I have the audio cables seperate from the power cables. I have the stereo grounded to the same place as the amp (right near the amps). The only difference is I am pulling power off of the wiring loom in my Jeep to the stereo, whereas I pull the power directly from the battery for the amp. Could the fact that the actual wires that go to my speakers are also in the same wiring loom as the power to the stereo? That would seem kinda stupid of Jeep to do that if it causes feedback, but oh well.

Any further insight would be helpful. :)
