10w6v3 would be a pretty great option for you. I have to build these by hand, so I can adjust internal volume accordingly. a bit over 1/4 a cubic foot seems pretty ideal to keep the enclosure from protruding into the cargo space tho.
If you are committed to one, please send me your zip and I'll get a final price with shipping for you, and a paypal address to make payment to.
Thanks again,
Mike
