4/0 is 0.46"
2 awg is 0.2576"
2x 2awg is 0.5152"
There is already a 10' run of 2 awg in place for the ground from the factory. I will be pairing this with a second 2 awg wire, for a total of 0.5152" thickness for the ground, as opposed to the 0.46" thickness of the 4/0 positive. Both grounds will go to the chassis ground bar, and a second 2 awg will go from the bar to the batteries.
I believe this will pass the same, if not more, power capacity, while saving money. After all, 4/0 cable is about $4/foot and 2 awg is less than $2/foot. I'll need about 10 feet each for the positive and ground, so this is the difference of $20 in cabling for the same capacity.
Unless I am wrong, then someone correct me. I don't want to burn the thing down.
