ModernDayHero07 Posted November 20, 2013 Report Share Posted November 20, 2013 I have a stock battery up front in the engine compartment and a CRESCENDO LOGIC F-31HP AGM POWERCELL in the back. I will eventually replace the stock alternator with a high output alternator either mechman or dc power but which ever one would be about 250A max; idling around 180-200A. I was planning on running one run of 1/0 from the battery up front to the battery in the back (+ to + and - to -). But after doing some looking and reading around, I feel like I'm on the edge of the 1/0 amperage capacity. Or am I reading the chart or thinking about this all wrong? The length of the run will be somewhere between 12'-20'. I know, it is a big range, but I'm trying to play it safe by overestimating.QUESTION: Am I safe with the one run of 1/0 or should I have another positive to positive 1/0 wire or also a wire from the back battery negative to the chassis also or one 2/0 wire, or what? I want to hear everyone's thoughts and suggestions! Oh, and what size of fuses (2 of them; one close to each battery, right?) should I get for the positive wire?

rickybobby Posted November 21, 2013 Report Share Posted November 21, 2013 TWO 1/0 is fine, one 2/0 is good also. you might... get away with one rune of 1/0...? the fusing should match you total amperage that you are running. that chart looks good. i think you are lookin at that correct. what kind of vehicle, amps are you running this is somthing simple to try. amps= volts/ohms amps=watts/volts amps=the square root of watts/ohms 03 s-10 owned since 35k now 150k alpine type-s 6.5 comp alpine type-e 10 ported fiberglass jl 300/4 (dead) jl500/1 (dead) Link to comment Share on other sites More sharing options...
ModernDayHero07 Posted November 22, 2013 Author Report Share Posted November 22, 2013 2007 Ford FusionI will be running about 2000W RMS for the audio system. That is about ~140A at 14.4V.Ok, so two 1/0 runs of the positive to positive. Do I put a fuse on each end of BOTH runs (4 fuses total?) And then can I leave the negative to negative at one run of 1/0? Link to comment Share on other sites More sharing options...
