Yeah, I saw the Kenwood thread, I just have no idea if the thing is good quality or not.
Personally, I am non-Bose, so I can just stick the amp under the driver's seat. And I would think that placing amps is much less trouble than enclosures, so just give first pick to the enclosure and make the amp deal with whatever is left.

My wife has that Kenwood one... and it's pretty good for the price/size. However... if you can find a seperate sub/amp/box combo that will fit, you'll be better off. There is significantly more space under the passenger seat as I recall... so I'd start by removing the bolts on that seat... tip it back so you can work underneath it... and start building cardboard cut-out boxes.
Figure out the biggest box you can build under there... and see what might fit. If you get the dimensions for the largest box that'll fit under there... there's lots of people here who can help you find a sub to work in that space. So far I don't think anyone's done this yet (component sub under the seat), so I would guess nobody has those measurements yet.
As for an amp... like you said, driver's seat works great. Plenty of room for an amp there.
Or... if you want the easier option.. go with one of those powered ones. I would describe their sound as "good, not great". I'm happy with the sound from the KSC-SW1... but it falls well short of the clarity and quality of sound from my single 12 IDQ sub.
