Ugh! What to do in a single cab F150!??

No room under the seat. I like the idea of tripple 8's, hell, I think two would be enough. I just need some nicer bottom end and not looking to be able for people to hear me booming from a half a mile away. What are some nice shallow mount 8's that are decent quality? I don't have a problem building my own enclosure if need to be.

The Pioneer TS-SW841D, it's got a 2.5" mounting depth and only requires a .15-.5 cubic foot sealed enclosure per subwoofer.
