I've got my 2GA wire from the battery running down the left side under the carpet and the RCAs down the right side under the carpet. Yet there is a plethora of wires running down both sides underneath the carpet. This equals high pitched whine at idle! I was thinking about running the RCAs down the middle but don't know what's down there. Has anybody looked?
Thanks,

Yes running rca's next to these wires CAN induce engine noise, a good quality RCA that is jacketed and loomed shoudnt induce any noise into the system. Double check all of your connections and make sure u have to metal to metal contact with the RCA's. DOuble check all grounds and or upgrade the grounding wire to a larger gauge.
Good Luck and Good Listening.

Here's a few things I found out..

make sure the head unit is grounded at the same point as the amps. If it is grounded to the original factory harness, then it is most likely grounded to a different part of the car and could be causing a ground loop. Try re-routing the ground from the head unit to the same point as the amps. Also, it might not hurt to run a new ground cable off the negative battery terminal and attatch it to the frame somewhere near the grounding point of the amps and head unit.

(note I'm not an expert on this, but I have been reading a few books, including the Car Stereo Cookbook, and they address this problem quite extensively. A lot of tips are given as to how to avoid noise problems.)

Hope this helps.
