where do you guys Ground to?

[mrlithium]

Clean ground is probably the single most important thing in car audio, so where do you guys ground to in the Grand Ams? have mine under my backseat, its aluminum though, i heard it should be grounded to iron. the trunk is no better. I want to know a specific good spot. Also I want to add a 0 gauge to the negative batttery cable terminal with wheres the best place to attach that to the chassis? I know some people have done this.

Yeah mine is grounded under my back seat aswell

A common place is to just use the seatbelt mounting bolt, after scraping paint of course.

I did what he said. Grounded to the seatbelt area

Why is the trunk no better? One of the best ways to ground an amp is to drill a hole in the trunk and put your own bolt in it, after cleaning the area up with a wire brush. Where under the seat do you have your ground? If it's to the seatbelt bolt, you're fine. If it's to the seat frame, I'd be wary of it.

As far as grounding the negative battery terminal, I'd say run a new bolt into either the fender or the header panel, you should be fine as long as the bolt is big enough and there's no paint there.

I just drilled into the aluminum seat frame, with a nut/bolt/washer + ring terminal and scraped well, the thing is that I am wary of it too. I said the trunk was no better because it too is also just that soft aluminum stuff, I didnt think of the seatbelt bolt though. I've been having some noise problems, I wanted to make sure the amps are grounded perfectly, otherwise it's my head unit.

The trunk shouldn't be soft aluminum as far as I know, last I checked it was steel, otherwise think of the dings it'd have from rocks hitting the bottom or stuff falling in the trunk area.
