bighossf150 Posted March 3, 2012 Report Share Posted March 3, 2012 (edited) For the wire from the alt to the front batt would 1 run of 1/0 Knu Kolossus be enough? Step up to 1 run of 4/0 welding wire?

Amart88 Posted March 3, 2012 Report Share Posted March 3, 2012 (edited) Depends on what your running. If you have more wire I'd do 2 Runs of 1/0 to be safe. Thats what Im doing. 1/0 ga is usually good for 170 amps and 4/0 is good for 260 amps. 2 runs of 1/0 would be ideal. I had 1 run of 1/0 with my 270 amp alt and it was fine but another run could'nt hurt. Edited March 3, 2012 by Amart88 Quote My 2005 s10 blazer build. 4 zcon 18's walled.

CJ18 Posted March 4, 2012 Report Share Posted March 4, 2012 I would use 2-3 runs of 0ga just to be on the safe side. It wont cost much since they will be short runs. Quote Link to comment Share on other sites More sharing options...
CJ18 Posted March 4, 2012 Report Share Posted March 4, 2012 Make sure that you have sufficient runs from the battery to the back also. If you have a secondary bank of batteries in the back, then I would do 1 run from the alt to the front battery and then 2 runs from the alt to the back batteries. This has worked well for me.

TeamHT Posted March 4, 2012 Report Share Posted March 4, 2012 2 runs would be perfectly fine, but like stated depending on current draw and battery bank, more runs to the bank shouldn't be neglected.

I have 100' of knu 1/0 kca to make the runs from the batts to the amp and from the front batt to the back, shouldnt be far, batts are going to be in the cab of an extended cab f150 so should be able to get at least 3 runs of + and 3 runs of -. The main reason I was considering the 4/0 is cause its only $2 a ft more than knu kol 1/0 Quote Used to have a loud truck 2009 Corvette Z06, H/C/I, 150 shot, g force tune, 730rwhp/690rwtq 2013 F-150 limited, MPT Tune, leveled on 35"s Link to comment Share on other sites More sharing options...
CJ18 Posted March 4, 2012 Report Share Posted March 4, 2012 Just stick with multiple runs of 1/0. The 4/0 wont be nearly as flexible and will be a bitch to work with in tight spaces. Quote Link to comment Share on other sites More sharing options...

OFC is almost double the current of CCA thats why it depends on what wire he has. Still Multiple runs of 0 gauge would be good. The 1/0 wire I ran said 180-220 can't quite remember. It might have been cca. Edited March 4, 2012 by Amart88 Quote My 2005 s10 blazer build. 4 zcon 18's walled. Link to comment Share on other sites More sharing options...
