1/0 2/0 or 3/0 welding wire

[kirill007]

I would do the 3/0, because it doesn't costs much more then 1/0 guage.

Overkill is good

Hell yea go big for that price.

I used 2/0 welding cable it's still very flexable big and not hard to run/hide

and hell it handles 300 amps up to 100 feet. right my front battery at idle reads 14.2v and the rear reads 13.3336. it has to be that crappy soundquest wire. and yes the rear batter was fully charged before i installed it.

2/0 welding cable will be more than enough lol. I have big 3 in 2/0 and running to my amp as well and could barley get that in my amp terminals lol. It is still a tad flexible but any bigger might be a pain. 2/0 welding cable is heavy as hell too. I fused mine with 300 amp fuses btw.

i'm hopen after the switch both batteries will read 14.2. not sure if this will effet the voltage but i'm running a 250 amp fuse at the front bat and right before the rear batt i have a 175 amp fuse. he ran out of the bigger fuses and usen this til he gets more in. then i'll do 2 300 amp fuses for the batt. and use the 250 for the rear batt to amp

Yeah if you get adequate sized wires running through your car, the voltage should match or at least be damn close

the solution for the big wire into 1/0 gauge ports is adapters. most places that sell weilding cable have 4/0 cable to 1/0 terminal adapters

Sonicelectronix.com carries them to

my voltage drop is between the batteries almost a full volt thats why i'm doin 2/0 welding cable
