I currently have one 12" CompVR in a box, powered by a Pheonix Gold T300.2 Amp. I just bought two 10" Kicker FreeAirs off of a friend, and a Profile Audio CL600 Amp. What would the best set up for these subs be, with out costing me too much money? Should they all be in one box, with the 12" between the two 10's? Should the FreeAirs be mounted somewhere else (I do not want to remove my spare tire though)? Any Ideas?

Thanks,

Sean
