MTX makes some awesome single 10" vehicle specific enclosures. They are not cheap though. But, I can attest to their subwoofer enclosures. I recently purchases a loaded enclosure with 2 12" MTX jackhammer subs and the box is awesome! Also check out sonic electronix. they sell vehicle specific enclosures too. And, they let you make an offer on their items!! Just click on the make offer button and they'll tell you if your price is too low. Plus, they are an authorized seller for MTX.
