HiWave BMR12 Compact 2" Full-Range Square Speaker 12W 8 Ohm
Can these little guys survive in an automotive environment, excluding the dash and the rear deck? I was looking to add them to the hefty B pillar in a Lincoln Mark & coupe ,2 speakers to each side .
Yes these are made of materials that will hold up fine in an automotive application.

Should I add a tweeter if using these in a 16 per side line array? I intend on building a pair of 16 driver line arrays like mentioned above in the reviews. If I do add a tweeter, where should it go? In the middle a la MTM? Along side? Crossover point
Adding a tweeter is very subjective. These are small enough to be full range although off axis the high frequencies will droop. I usually recommend hooking them up full range first, then you can always add a tweeter later if you feel like they need more top end.

Looking to use 18 of these (to achieve 4ohm) in an edge-to-edge linear array as the center channel for my home theater. Planning to mount the array vertically (as recommended) and behind the acoustically transparent screen. Any words of advice/caution?
I don't find anything wrong with the theory although you will not achieve a proper 4 ohm load with 18 drivers. 4 drivers will bring you back to 8 ohms, 8 drivers will drop it to 4 ohms and 16 drivers will bring it back to 8 ohms. I would recommend either 8 or 16 drivers for an application like this if you need an overall load of 4 ohms or higher.

What would happen if I used this speaker, with no filter, as the back speakers in a surround system? The amp is rated at 100 watts, but I never turn it up very loud at all.
Generally the surrounds will not produce much bass. If you are playing them full range you may have a problem with some movie passages, especially since these are so small and inefficient meaning they will have to be turned up quite a bit to hear them. i would recommend a high pass filter on the receiver set no lower than 100 Hz.

I am building 2 bookshelf speakers w/ 4 of these in each, wired series/parallel. I have 200uf non-polarized capacitors to add to each driver. Where do I add them?
With the drivers wired in series/parallel, the easiest way to do this is simply to put one capacitor in line with all four, series to the positive input.

Can I wire 5 of these in series/parallel to maintain 8ohm impedance?
Unfortunately no, the only way to maintain an 8 ohm impedance is to use four. You would have to wire them all in series in order to use 5 which will yield a 40 ohm load.
