Ok. The whine is coming from the head unit. the amp is fine, the rca cables from the HU to the amp are fine. I grounded it to the chassis at the bottom of the center stack and I'm still getting the whine. the only ground that I can't control is the antenna. the system works even with the brown wire ground disconnected because the antenna grounds the system. But even with the antenna disconnected and the system grounded via the chassis ground I still have the whine. The last thing to try is a direct power from the battery. I can't seem to isolate the source.
uhg!
