i also have the perfect sub for you, it is a 15" tc-9 hybird, with HCCA motor. dual 2 ohm, and will handle 800-1500 watts rms, with no problems. i had it ran off 1100 watts in a 3.4 cubic feet box. it slamed, had awsome bass, with great sound quality. you cannot go wrong with this sub. and i will guarantee you, you will love it and it will shake the hell out of anything you put it in. the link to it is in my sig below. let me know if you have anymore questions or need anyhting else.
