wait..

how long is the power cable?

how long is the ground?

If the ground is only a foot long, and the power is 20, than 4 ga ground would be fine

i actually have 3 in questions:

1) ground connecting 2 HC2000 bats (about 1 ft)

2) ground from 1 of the extra bats in the bed of my truck to the main bat in the engine bay

3) ground from amp to extra bat (3ft) and power is about 3ft

If you're wiring up batteries, I would most definitely suggest 1/0 all around.

i thought you were talking about running power and ground from the starter batt to an amp somewhere a way from it

for batts, use the biggest you can fit.. for runs that short, it wont cost that much for using 1/0 all around, and it **** sure wouldnt hurt

thanks. another question: i have 3 ground leading toward one of my extra batteries. 1 is from my 2500.1, another is from the other extra bats, and the last is connecting to my original bat in the engine bay. question is, should i route all of those to an unfused distro block and then to a bat terminal or should i just snag one of those terminals that support 3 runs of 1/0 from knu?

Putting them all on the battery terminal is the best, IMO

well i know that knu and i believe jl both have terminals that can support 3 runs of 1/0, know of any others?
