Amplifier ground points.

Hi all, in a few weeks/months I will probably start working on upgrading my sound system. Too far out to really nail down what kind of equipment I want. I won't be running a sub, but rather a 4 channel amp and 4 speakers. From the looks of it, amp installs are fairly easy on this car since the battery is underneath the rear seat. I'm guessing the easiest way to do this is to install the amp in the trunk and run the power cable straight to the battery, going underneath the seat/seatback? I will be running all new speaker wire as well...but the one thing I'm not 100% sure on, is the ground point for the amp. I am wondering what everyone uses to ground their amps if installed in the trunk? A pic of the location would be most appreciated as well if it is in an obscure spot!

Thanks!

I have my Amp grounded under the rear seat. If you pull the seat out, you'll see that there's ALLLLLL kinds of bolts to ground to. The bonus to it is that they're all near the battery and in clean, thick metal. I believe mine is actually connected with the battery's chassis ground point.

Like Abaddon said there are plenty of places to ground under the back seat. Mine is grounded on a large bolt on the drivers side IIRC. Both power and ground can then be run under the top half of the back seat into the trunk.

When my system was installed, I grounded components direct to the battery via a distribution block, similar to the way the power wires are connected. I was told noise could be a problem, but I didn't notice any. It's a bigger cost for wiring, but I liked the way it presented.

Functionally, I don't think it makes a difference as long as you choose solid connections to the chassis. Be sure to scrape away paint where the connector mates up. Use star (crush) washers to get a good bite. But with the battery just a couple feet away, I opted for grounding direct.

The old wiring set-up:

AA, did you ever finish your new setup?

Nope. Got a little work done, then put on the back burner. Reinstalled the trunk liner, so it's like stock until I can get back on it.
