I have rockford 400.4 pushing my 6.5 rockford component door speakers (98 with power doors, yes tweets fit in stock local thanks to the dremil) and my 4x6 coaxial in the Bpillar. Got a sony 1300 wat amp pushing my 2 p3shallow 10s in a custom box with a rockford 1 farad cap. I'mdoing big 3 mod this weeekend, that should help give me a lil more umph. I listen to breaking benjamins, nickleback, stuff like that. And a lot of country. The 10s are more crisp and don't resignate like a 12s (4 8in subs would be bad ass) and my doors are loud as crap, I know just enough to get me in trouble. Google what you want to know, save the pages and study up on them, and you don't have to spend a ton.
