It is going to be for music. Not much interest in taking just that much to competitions. I would still like to get it as loud as possible for just an every day vehicle. Use all 1/0 wire, do big 3, and run a second battery in the rear. Thanks bro. I have the 1/0 wiring kit already and was planning on doing the big 3. Didn't know about another battery or bigger alternator though.
