Why do you think that you want to run that much power? What's your budget? What's your budget for alternator, batteries and wiring? How many subs? What size? How much room do you have? What vehicle?
My budget is about $5500 including sound dampening, wireing, and everything. I have a 1990 toyota camry so the number of subs would depend on the size because I only have so much room, but I'd like 2-12's, 1-15, or 1-18.
