stay away from those main stream brands guy. they arent any good for the price your paying.. im running an AP 3000d amps, and 1 RE SX 12 D2, i pulled up to my buddy whos never heard of either of these brands, he had a Hifonics brutus 1600watt amp, and an Alpine Type X. I blew him out of the water with my simple setup... im not even close to running this amp at full tilt, not even half, and its great to me. simply check out other brands. RE SE subs are great for your price. AQ HDC, diamond D6, its really what you chose, but anything they sell at bestbuy really isnt all that great for the price. Good luck though, everyone has different tastes.
