The only problem I see with the enclosure reccomended above is that you won't be getting nearly the SPL that sub is capable of producing. You say you have an extended cab, if you really don't need that extra space in the back, I would try to get an enclosure that was at least 2 ft/\3. And if you really want some boom, then you might want to check into a ported enclosure, and if that's the case then you would want to go with a little more space.
