Not that I expect you will but if you ever decide to sell those Alpine tweeters, keep me in mind. I used to own a pair in 2010. Loved them. Changed installs and they were sold.

The Scanspeak tweets offer a lot more detail than the cheap plastic Bose units. I can now actually hear parts of music the Bose tweeters could not replicate. However, something still seemed off. I could still hear shrillness in some songs that should not be there. Hmmm... What's going on?
Then it occurred to me. There is another set of Bose tweeters in the rear doors. Let's take a peek.
You can remove the rear door mid-range and tweeter grill by hand. Just grab by the red arrows and gently pull towards you.
I found this interesting. I popped off the grill on the passenger side and noticed this tweeter was damaged from the factory:
It's easier to remove these tweeters. Just put your finger through the empty midrange hole (red arrow) and push on the tweeter from behind. Next, release the plastic clips (red arrows) with your trim tool and the tweeters will pop out.
I tried listening to the system with and without decent tweeters mounted in the rear doors.
Having high frequency content near your ears right behind you was screwing up frontal imaging. So, for now I am going to remove tweeters from the rear doors altogether. The signal going to them is full range. I can probably use that for something else in the future.
The door also has 6-1/2" mid-basses mounted below. I may end up using the 6-1/2's for L-R rear fill in the future. Either that or I will install 3" mid-ranges in the factory supplied locations. Either way, the rear fill will be band limited from 250Hz to 2.5KHz. But, that's a project for another day. I don't have the amps I need to complete this configuration yet.

These are re-branded Scanspeak 2904/60001's. They were part of an Alpine F1 component set a long time ago. They have been my "go to" tweeter since 2008. However, they have been out of production for quite some time. They are getting harder and harder to get a hold of.

OK. time to check out the center channel situation. Mainly because it is easy to do
Start by pressing the lap clock towards the windshield (red arrow). This will lift the trim piece up enough for you to get your plastic trim removal tool under it (green arrow). But, just break it lose. Don't try to remove yet:
There are two J-hooks you will need to release before you can pull the vent panel out (red arrows). The trick to doing this is to leave the vent panel lowered so the J-hooks clear their locking point. Press away one side then lift that side slightly. Then do the other side. The vent assembly will then lift so you can do other goodies. This is the hardest part. Clear it and you are on your way.
The only thing holding you back now is to release the connector to the LAP clock. Just push in the retainer tab (red arrow) and pull the connector out. Once this is done you can set the vent assembly aside:
Now you have a clean view of the center channel speaker
You'll need to remove those torx bolts. But after that you are home free. I managed to get my Bosch cordless screw driver in there with the appropriate bit and still clear the windshield.
Again, press against the connector retention clip to release then loudspeaker. Easy peasy.
Looking inside the hole I see a somewhat sealed 1 liter enclosure formed by the A/C vents. This may be useful...
It looks like you can add a mid-range with up to a 3" cut-out into this hole. Also, depth does not seem to be any problem for such a driver.
At my photo limit per post...
