OK to use for Amp Ground? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I want to use one of the studs that holds the trunk cowling as the ground for a replacement amp. I wire brushed the pain off it and got 12+v reading
at the stud base. Is there any danger to screw the fastener back on as long as it doesn’t touch the ground ring terminal?

Id recommend just using the battery or the battery to chassis spot.

That battery post terminal isn’t really a ground as it’s part of the battery and not the chassis. I’m already using the trunk ground stud for two other grounds so I’m reluctant to disturb it to add another ring connector, plus I’m thinking I might get some noise from it because of the other
connections ?

I used it not for the Main ground but the amp had another ground wire for another feature and I hooked it up there, It appears to be working fine.

you can take the bolt to any hardware store and get it longer, or run a ground to another spot. personally, youll be fine direct to the battery. Thats the only grounding point in the corvettes and when doing audio in them, we run power and ground direct. All the ground goes back to the battery, so direct to the battery wont hurt anything. If you hear a ground loop, then you may have to find a different spot

I used the battery also without issue. Or like other OP said, get a longer bolt.

Another option is one of the bolts on the battery cover bracket as long as you remove paint. Check it with a meter.

Amp is in and playing fine … turn signal blinker sound is louder too! I did wind up using the lower trunk cowling stud but didn’t screw the cargo net retainer nut back on. Both cowling and net fit fine

Thanks for the replies and suggestions.

ps - BIG shout out to Steve at ******** for his FARK harness and eom-fit mounting board !

Agree with that, not sure why It's censored here, but I have bought several quality parts from him!

Congrats on getting it done.

Thanks! What a difference in sound. Wish I did it sooner.
