In a non-extended cab, when a person needs the seat to go all the way back, you almost can't do anything bigger than 8s. And that's not a bad thing, with the great selection of quality 8s that are out there now. The ED 8s are great.
Daws.. I was just thinking of doing something really similar... downfiring some small subs. Doing it that way seems to open up some more creative options.
I've seen a guy do two 6.5" subs in a regular shaped truck box wedge, but with the subs mounted in the sides of the box, facing the sides of the truck (toward the 6x8s). It sounded really good... and he didn't have to worry about the depth of the woofer... he had all the depth he needed.
I've toyed with the idea of building a subwoofer enclosure into a center console - maybe do one 10" woofer, firing toward the rear. I want to put some bucket seats in my truck anyway. But I depend greatly on the drink holder, and I think it would rattle the heck out of any drink that I put in there.

I had 2 of the Elemental Design Eu-700s (same as current e3.6s) in a 1ft^3 ported enclosure tuned at 30Hz and it sounded really good (in a Scion tC). And was very surprising in output for what they were. It's amazing how dependent a subwoofer's performance is on the enclosure.

Here are the best* available dimensions for a behind-the-seat enclosure, with the seat adjusted all the way back.
48" wide
13" tall
2" wide at the top
7" wide at the bottom
This gives 1.5 cb ft of external volume. Internal volume will vary of course, depending on the thickness of wood that you use, and the woofer displacement itself.
*I say "best" because this is the simplest box to build. You can probably squeeze a little more out of it if you're good at building a custom box. It wouldn't be that hard to make it a little wider.
However, the greatest limiting factor is the 7" depth at the bottom, which decreases quickly as the box tapers up. You're going to need to keep the depth of the speaker in mind... and mount it as low in the box as you can.
I think I'm going to use 4 of these... in a sealed box of the same dimensions as I described above. I'll probably use 5/8" MDF with a center brace, fiberglass the crap out of the inside of it, and cram it full of polyfill. Carpet to match the interior and be done with it.

How about removing some of the seat back material to gain a little more sub box room? I don't have my f150 yet so I can't really investigate.
BTW, those TangBand 6.5" are mean motha's too! The eD 6.5" has a deep and wide motor structure so I don't think they'd fit in those dimensions downfiring.

eh... the limiting factors are mostly in the back edge of the seat bottom, that is, if you're intent on keeping the seat adjusted all the way back (which I am). Removing the seat back material will not allow you to make the box any bigger... at least not from my observations and measurements.
You can't remove the seat springs. That's what my 10s are jammed against. The magnet pretty much touches the back of the box, and they're mounted low. I think I have my seat one notch forward.
My picture on page one of this thread shows my seat back.
