OK, with more thought, I think that two 12"s would be my best bet. I want bass that I can feel. Everyone I know has gone from one 12 to two 12s, so wouldn't it be smart to just start off with the best? I'm going to listen to a few of my friends' set ups first to see what I like. And the only people that like 10s are the ones who listen to a lot of rock. I like rap more and I want to really feel the bass. I'll just make sure to keep it down at night.
And here's an example of the Rockford Fosgate dual 12" enclosed subs. Are these bandpass boxes or are they ported boxes (noob Q)?:

The big question: can I get comparable subs and a separate box for cheaper? Will it sound as good?
