Amen... true true -- but, if you have some creativity and a guts, you can
make it sound great.
Like others that have asked before, go to Huw Powell's page at:
He's got _everything_ there that you need to know. And, being a
speaker-design guy, I'd assume that his ear is at least as good as mine
He has a good approach, but needs a little snipping of the metal that
resides below the rear deck. He suggests making your own rear deck out of
something substantially stiffer, like MDF or particle board (I'm
paraphrasing here...) and snipping the metal to either vent a enclosure in
the trunk into the cabin, or to allow drivers in the deck to use the trunk
as a sort of infinite-baffle enclosure. Enough here... hit the site.
It might be more than you are barganing for, especially if you do not want
to cut your car up.

I've stuffed a sealed enclosure with on 12" subwoofer in the boot of my
4kq. Penetration is okay... just don't expect to be pushing much air into
the cabin. It would be nice to be able to use it like a true hatch-back
and have it all in the same airspace, but try it. It's easy and works
okay. I've just got it for low-end extension.

The PO of my 4kq had cut into the doors in the front. Smartly, though, he
mounted the drivers _beneath_ the panels. He (okay, coulda been a she...)
also cut the cardboard backing where the speakers would mount to make
panels a little more acoustically transparent. Works quite well. Ask
Huw, he's done similar things.
I'd avoid cutting, if at _all_ possible. In the door you probably want a
5.25" driver. I've stuffed a 6.5" driver in there and it _barely_ clears
the window. I think it is 2.2-2.3" deep. Also, you have that
door-jamb-catch that you have to watch out for. Good way to poke big
holes in your drivers. Otherwise, if the UrQ dash is like the 4kq, you
can get at most a 4" or so driver in the dash. Maybe a nice 4" coaxial
set? Dunno about imaging.

That would be cool. The further you can get the drivers away from your
ears the better, IMHO. A little more costly for kicks, but worth it for
that cool-install look :). It's up to you and how much $$$ you have to
spend. As far as I can tell, the little kick that's already in the
footwells can be unscrewed from the side by lifting the lower and away
edge of the carpet to expose a screw. Might be a good place to mount your
new kick panels to.
Still, I would go for stealthy over flashy.
