ok so im wiring an amp and i got the power wire through the fire wall
and all that stuff but i dont know were i can ground the amp. So if u have subs and anamp what did u ground it to?????

 

Get a self-drilling bit screw and just screw it into the frame of the car, alot of people do that or either bolt it up to a bolt already placed in the car. As long as the surface is clean of paint it should be fine.

 

I searched long and hard and found the best place to ground is one of the bolts on your shock tower, behind the carpet, gets the best ground, I have 2 amps and 2 caps grounded off of there.

 

dont do the self tapping, zippy head screws because they do rust. best ground would be the shock tower like he said because its a close connect with the ground

 

ya u saw that is it ok if i screw that out to put the ground in i was afraid that it would
mess something up.

 

Nope there's 3 nuts holding the bolts, and if you unscrew one, the weight is still on the suspension, perfect to ground on, like i said I have 2 grounds off them and they're perfect. Even when I went through with a voltmeter, the best grounding point I found was the shock towers

 

sweet thanks now i can finaly finish my amp install
