Not to sound like a dick, but with your kind of budget that kind of system wont happen, the amp or amps will cost you 900+ unless you want to go the cheap way, batts will be no less than 600+ unless you buy cheap batts or used, a h/o alt 400+, subs to handle 6k 300+ each sub, sound deadener, mids and highs upgrades, multiple runs of zero gauge, possibly custom door pods,materials for box building, imo bring your budget up to 4k+ or step down to maybe 3k-4k in power.
