Best ground point for area behind rr bar

frankiev · 06-12-2015, 02:11 PM

I have two amps to mount in the area behind the strut bar . i know this is a popular area to mount amps but I wasnt able to find a post regarding the best ground point . Ive been using the seat mounting bolt up untill now but I upgraded the amps and theyre too big to fit.

cant u just get a ring that will fit ur new amps' ground wire? just solder it?

or take ur multi-meter in volt mode and probe candidate bolts for a clean 0.00v against ur seat mount hole or known ground.

Not sure what you mean . Connect grounds to same seat bolt? thats too long of a run isnt it. I know how to use a multimeter but Im Not sure how to test for a good ground ,can you please explain .
I was hoping someone could just tell where they put thier ground

looked it up on utube so now I know how to find a good ground but Id like to use a factory ground if anyone knows where theres one close by

From what I remember with the hatch interior completely removed the closest one is prob the same distance as the seat bolt. Its close to the driver side taillight.

A ground is a ground. Doesn't matter where you connect ground, as long as its a good ground source.

For the short distance involved, the same size ground wires (one for each amp) as the power supply wires (assuming they are sized properly) run to the seat bolt (or just about anywhere else in such a small car) will work great.
