Grounding Questions
I've recently installed an amp in my c6. I mounted a pdx5 on the slope behind the passenger seat. It's grounded on one of the seat bolts. To get the ground, i had to take the paint off of the bolt and nut. The problem is that i have a whirring sound when the engine revs. Is this caused by a poor ground? Is there a better place to ground on a c6 that is close to the location that I chose for the amp? This noise is driving me a little nuts, it sounds exactly like a dentist drill. No offense to any dentists, but i cannot stand that noise.

Ground problem
Funny you should ask. I had the same problem when I mounted a pdx 4.150 behind the passenger seat. It is an extremely difficult problem in the corvette. The only way that I found to pretty much get rid of it is to run a ground wire from the back of the radio to the bolt that has the amp grounded to it. It almost complete eliminates it and I tried ground the amp a few places. So that is my suggestion to you. I hope it helps.

Hope that helps, and it's a lot easier than running a wire all the way from your deck....
