Quick please! Which ground!?! PIX***

[solidcrowd 10+ year member]

Was wondering which would be a better ground, first picture I was thinking off bolting it to one of the bolts....second picture is the rear lid where the rear fill is. Those speakers will be taken out all together anyways.

Or none are good options?

If that bolt is attached to the chassis of the car then go with the bolt. If not, then just go with whichever one is most convenient and if you have problems you can switch.

I think I read awhile ago that I can test each spot with a volt meter? Not sure how to do that or if it can be done.

I'm not sure where that first bolt is but if its attached to the frame its good, but id make sure to clean off all paint and hit bare metal

usually i like rear shock bolts above the rear wheel well

The bolt is one of 4 that holds the shocks to the car I believe....It has a rubber cap covering the middle bolt...

I don't know I saw this:

"I believe that there are both ground resistance tests and ground impedance tests. "Fall of Potential Method" as an impedance test. Impedance tests are important when the resistance is .5 ohms or less, not the 25 ohms we are used to"

Okay better picture...Now a couple questions:

1. Each bolt has the nut and washer I will be using. I dont want to unscrew any thing, so i'm going to be bolting it ontop of the existing plate or nut. Which one would be the better choice?

2. I know grounds are supose to be short as possible, soo I have an amp on each side of the car. Could I ground from each shock or will there be a ground loop? I don't want to have a ground 3ft. long to reach the other amp.

Im not sure how those bolts and nuts work but just make sure your hitting bare metal somewhere, clean off the bolt with maybe a wire brush just to try to get the zinc plating off and sand or wire brush the bottom of the nut, just make sure its clean and do a good job the first time or you will regret it.

and you can make as many grounds thoughout the whole vehicle, it doesnt matter what so ever

i have my ground to one of my shok bolts. just undo one and u will be ok. it will hold up for u to take it off, put the ground on, and put the bolt back on.
