My parents are giving me my step-dad's work car, which is a 2001 Ford Focus ZX3. I'm looking for advice of what to put in it system wise. I had two Kicker Comp 10's in my Bonneville pushing 1200 watts and hated it. I was thinking about going with 2 10's or maybe one 15. My head unit will be a Pioneer DEH-4300UB LINK: http://www.crutchfield.com/p_1304300UB/Pioneer-DEH-4300UB.html?tp=5684

What subwoofer/amp combo would you reccomend for my setup, and what door/back side panel speakers would you go with?
