Best Ground

[Fender5 10+ year member]

Should I ground the battery where theres an existing bolt?

or where i drilled one

thats where my amp is grounded right now.

is it safe to ground 2 amps, and a battery to that same piece of metal. i would drill 2 more holes and sand those down too.

or ground battery in the first pic and ground two amps in the 2nd pic?

The best ground is wherever you can find the lowest possible resistance.

Rule of thumb is to ground everything together where possible.

so ground all 3 at the same place in the 2nd pic?

thats a good 3-4 feet from the position of my rear battery. Isnt that too long

im not exactly sure where that bolt is in pic one. I think its under the rear deck holdin something

Like I said, the best ground is the one with the least resistance. A 4ft cable run using the appropriate cable diameter won't give you any noticeable resistance.

If this was so you could only have one amp and no battery.. think about.. the car is all one big piece of metal.. well what you would be grounding too anyways..

so are you sayin that a 4 ft ground of 0 gauge wont make any noticeable resistance?

most amp wiring kits give u a 3 ft ground wire..i dont think 4 would make any/much difference
