I need help with setting up my Car audio system?

I recently purchased Kenwood KDC-X693 HU, KFC-XW1200F 12" shallow sub, Focal Access 165A1 components, Boston Acoustics SL65 coax, Kenwood KAC-8404 4 Channel and KAC-8104D mono amps. First, I wanna ask if this is even a right equipments for my Mini Cooper and secondly, how to set gains and frequencies for perfect sound. I haven't had much experience with car audio or any kind of audio other than Bose already setup systems. I need major help setting this car audio system. I pretty much listen to music very loud so I'm very cautious about blowing speakers.
