[brooksi 10+ year member]

im goin with a 600 watt amp what size wire should i use, my car is wired with Rockford Fosgate 8ga from my old system but that was only a 200 watt amp and i was wondering if 8ga would be enough or do i need a larger wire.

If you can afford it go out and buy some 4 gauge wire and 4 gauge ground it's not that much 20 feet will run u like 35$
