If you want that subwoofer, I'd get it here:
Kicker 10CVT102 10-Inch 800W Power Shallow Subwoofer : $83.95 : VMInnovations.com
That comes with free shipping, and you can use our forum discount to get 10 or 15% off.
Or you can buy it with the enclosure here
Kicker 10TCVT102 10-Inch 800W Loaded Subwoofer with Enclosure : $132.95 : VMInnovations.com
And get the same deal. I don't think it's worth the extra $50 though. Personally I'd never buy any of that stuff, but $80 aint bad at all for a kicker.
EDIT: You do want a single 2ohm subwoofer, or a dual 4ohm, that's a must.
