Good idea, but...

I disconnected the ground wire on the harnesses. THE DAMNED HEAD UNIT STILL OPERATED, but with an increasing amount of whine. I found a bolt in the dash, used a screwdriver to get to bare metal, and touched a wire from that point to the h/u's ground wire. The whine decreased almost to where I could not hear it. Turning the engine on created whine, but again not as intense.
Grounding to the amp results in less whine. I always thought that those isolators didn't really do anything and that having a solid ground would eliminate alternator whine. This ground is super-solid. Oh well...
You are a half-hour south of me! I'm in North Aurora nowadays
