I obviously know nothing about car audio yet.
I'm looking to build a system that a good full deep pound (rap) filled out with a full range high quality mid and high end (I listen to all types of music).

I was thinking 2-12s would suffice for the bass but what other kind of speakers should I match the 12s with for the full clear sound?
..9s? 6x9s? tweeters?

In other words just in terms of speakers what is good to match with 2-3 12s? leave wattage and other complications for later.
Thanks
