Rob, GM does not use crossovers for the tweeter and woofer
separates in the front doors. The components are simply wired in
parallel. Not the best for sound quality, but I guess it's
cheaper.

The speaker covers are attached to the rear deck covers with nuts
that are put in from the back. Basically, the speaker grilles
have a series of posts on the perimeter (maybe 6 or 8?) that
protrude through the rear deck cover. I don't know if you've ever
seen these nuts that look like they've been stamped from a light
gauge sheet metal, and are used to self thread themselves onto
the plastic posts.
You wouldn't be able to pry the covers off without damaging
something.
