Re: only one run of 0 gauge??
I previously had the bc3500. My electrical was/is 220@ alt, 4 runs of 1/0 wire(2 power + 2 ground), i double up because it is cheaper wire and i got it for a REALLY CHEAP price so it gets the job done. I have a complete sh1t(lol its going to be changed soon) battery under the and 2 Deka agm's in the rear(1-105ah & 1-85ah).
With the bc3500 wired at 1 ohm playing full tilt while at idle RPM's i was only dropping to 13.5v or 13.6v at the lowest from 14.2-14.5(normal idle voltagedepending on the temperature). At 2kRPMS i dropped to 13.9-14.0v
And thats with CHEAP "INSTALL BAY POWER WIRE" LOL.. Im sure if you get a good 1/0 wire you will be fine.
