im saying tou should check craigslist. people that got bored of their systems sell them at low prices. you can get 2 12'' subs, a decent ampt and possibly wires sometimes for 300$ and an amp kit will only run you about $30 in walmart or $800 in best buy for brand name wires. but if your looking for new quality things definately get like 500-800watt amp and possibly 2 10's
