Welcome to the club!

Here are some plans for a standard MM2124 box. http://www.polkaudio.com/caraudio/subbox/subbox_plan.php?id=58&mesurements=standard

You can play around with the dimensions in order to get them to fit under your seats but youll still need to have 1.6 ft3 of air space for a pair of 12's.
