Wow Tim, that was actually what I'm going to do with the tweeters. I'm
still working on what I'm going to do in the rear. You could go with
another set of separates with the tweeters mounted just behind the door
post. I'd also like to figure out a way to run a conventional small
sub. I'm thinking that they could mount flush in the vertical area
behind the seat, but that would take the place of the mid-range's from
the component set. We'll see.
But all that is down the road a bit and the mechanics are still taking
up my time. The GTA's Polar Bear run is Saturday, and then early next
year the tranny comes out again. I hope the 3rd time is the charm.

To get around the tweeter issue, you might want to try buying component
speakers, or "separates". These have the woofer as one speaker, and
the tweeter as a separate piece. You could mount the tweeter unit on
top of the dash, in the upper corners of the windshield, or maybe even
in the holes in the dash where the swivel vents are.
The power output that is in big print on all the radios is max power
(ie 50W x 4 channels). The figure you want to look at is RMS power.
This is the maximum sustainable power output at low distortion rating
(be sure that the RMS power output figure is at a low Total Harmonic
Distortion - THD - percentage). Most quality aftermarket radios today
put out around 17-20 watts RMS. If you want more power than that,
you'll need an external amp. I have a 50Wx2 RMS amp in the trunk,
wired to two 6x9 speakers in boxes on the rear deck. I can hear the
tunes clearly up to around 70mph with the top down, but bass output is
not very good since the boxes are kinda small.
In my opinion, the ideal solution would be 5.25" or 6.5" separates,
with the woofer mounted in the kick panel and tweeter in the swivel
vent holes, and a small base tube on the rear deck. 50Wx4 RMS amp,
with rear channels bridged for 100Wx1 into the bass tube, 50Wx2 into
the separates. The sound quality would be great, even with the top
down over 80mph!
