    Post Okay, Back to the Engine Noise

    Well, I hooked up my player. Everything seemed okay, except I heard a buzz at higher volumes. Checked my ground on the inverter -okay. Then I realized that I hadn't grounded my case. Went ahead and grounded the case, and voila, the buzz was completely gone. Only problem is, when I started the car a minor buzz had turned into major engine interference (whine). Anybody know why grounding the case would have turned a minor buzz into major engine noise and how to fix it?

    Thanks.

    Problem solved.

    First, I ran the power line down one side of the car and moved the RCA line to the other. That helped a lot. Then I grounded the case to the same location as the inverter ground. No noticeable change there. Then I put in a ground loop isolator that I had bought a few days ago. Voila, no engine whine or buzz. The other day when I tried to use the ground loop isolator it caused extreme static - caused way more problems than it solved. I was ready to take it back to the store and as an afterthought tried it again this morning. I donít know what was going on the other day but there must have been a combination of problems going on which caused the GLI to make things worse.

    I've heard people naysay the isolators, but it certainly did the trick for me.
