Maybe this could be a solution:
Wicked C.A.S.*::*Magic Boxes*::*Chrysler*::*Chrysler - Crossfire Coupe 1X10
Wicked C.A.S.*::*Magic Boxes*::*Chrysler*::*Chrysler - Crossfire Coupe 1X12

Would also recommend to sell your old subs and buy a new one that has tsp's that fit to the volume of the enclosure. Or else build an enclosure for that will fit to the tsp's of your actual subs. (tsp = Thiele & Small Parameter)
