just like the title says, how many 0 ga runs do I need to hook up a powerbass 3000d to a yellowtop battery, I was thinking about running 2 runs of 2/0 ga pos and neg from the battery to the hatch to the amp, or do I need to run 2 runs from the chassis to ground on the amp, i am a little confused on that issue, either way how many runs do you suggest?
