you can either make a box for it, or have any stereo place like Boomer McClouds or Tweeter make you a box. For one 12 it shouldnt cost more than like $125 from a store. If you build it yourself, just run to Home Depot or the like and buy .5 to .75 inch MDF board and buy something like bondo. then just cut and sand. and then put some carpeting on it.
