I'm using welding 1/0 dual runs for a Big Boss 3k and that's fine for that i think but can i move up to a 5k on those dual runs of 1/0 they don't look to be oversized def some sort of US standard 1/0 but man they heavy it's some real deal wire. Big D and Parker tested these amps getting like 7-8k out of the 3k and almost 10k off the 5k so got me worried on actual ratings vs wire needed. Still in the past running x2 AGMs 70 ah starting battery and 100 ah audio aux battery in the trunk i know if i move to the 5k i'll need to swap to a couple lithiums already to go on that front with a isolator installed.
