bass, explorer sport trac?

I have a customer with an '01 Sport Trac, and I'm wondering what kind of subwoofer setup anyone's put in to one of these vehicles. I've currently installed this enclosure, and I can't seem to find any subwoofer that will a) mount in the enclosure without rubbing the bottom of the passenger seat, and b) produce sufficient SPL. Ideally, I'd like to use that existing box, because it's already mounted well and there aren't any prefab alternatives that I could find. I've looked at the Kicker CVT 10" which doesn't seem bad, but I'm concerned that it will be inadequate in such a small enclosure(their minimum recommended sealed enclosure is 0.8 ft^3). Suggestions, everyone?C Renner's Auto Electronix

just curious if you got your customer talked into letting you do one of these yet??

No, actually, but thanks a million for the response - that's slick and I might show him the photos as an example. My skill with fiberglass is somewhat limited but I do think a similar setup might work for this application. By chance do you remember how much airspace that enclosure had?

i dont really remember off hand but its more than it looks. ive done a few setups with it and i just adjust the airspace inside for what i need. ive put a single 10" driver in a few and they sounded great.
