Anyone have any half decent specs for a box in a 89 YJ. Buddy is going to let me remove his back seats, just want to know if any you old bass heads have ever done these before and if you have a design that works. 2 tens

 

Done 4 12's in a yj with no backseats. Fired all the subs and ports into a common chamber and then fired them through a really big gash of a slot into the area between the two front seats. The box will be dependent on the two 10's that you either have or choose. In a YJ, something ported (Dukk is secretly nodding) is going to be in your best interest.
