amp ground 88 vette

where is the best spot to ground an amp in a corvette since the body is fiberglass?, if anyone has experience doing audio systems in vette's, some help on this would be appreciated !

Make that the battery, not the frame.Top Secret, I can tell you but then my wife will kill me.

i ran it to the battery originally, end result- alternator whine. customer had an old school din and a half pioneer head unit with no pre outs, so i fed hi-level into a brand new mtx amp (which i provided), car came back, and i temporarly hooked up an alpine head with 5volt preouts and noise went away. i told the customer to get a new head unit and we will try that, so he got a new panasonic with 4 volt pre outs, only thing im worried about is even tho i tested it with my alpine, obviously the rca's i hooked up temporarly werent run permanantly, so im just crossing my fingers that when i install the new head and run the rca's i wont be picking up any noise along the way! so im just trying to cover all bases to avoid looking like an ass if he still has any noise with this new head unit. i had thought about running the ground to the frame, but wanted to try avoiding drilling a hole through the body of the car and running my ground through it to keep the ground length shorter than running it all the way back to the battery.

I was going along the line of keeping the amp grounds as short as possable.Alpine CDA-9833 HU
