Can't find good ground

[poweraidon]

I can't find good ground for my amp. where can I find it?

Chisel through some paint, I had to do the same in my truck to get a decent ground. They use thick paint on our rigs.

Use a test light and poke around until you find one, or chip off some paint as mentioned. Although you should still test the metal as a good ground with a test light once that is done. I just wired up my new switches and had some really weird things happening after wiring up my fog light bar. Turned out to be a bum ground on the fog bar harness.

I'm trying to install it in the trunk but it's covered with this rubber mat thing? And can't find a ground anywhere

there is metal under that mat, but honestly, why not pull the left-side panel and use the grounds for the stereo that are behind the panel (in the cargo area)

I grounded mine to one of those triangle hooks on the trunk floor under one of the bolts and worked great for the year i had it installed.

FIRST & FOREMOST...check the main ground from the battery to the frame. All other grounds mean nothing if the current cannot get back to the negative post of the battery. The H3 is famous for having bad battery cables.

Where is the amp being mounted ?

I always ran 4 gauge from the amp directly to the frame...I cleaned a spot up good down to bare metal with a grinder, then drilled a hole, then bolted the ground wire to the frame.

Best answer! There are easily accessible grounds right there. If that's too far of a run, just create your own as stated above.
