The rear panels are almost a lost cause. There is not enough baffle room for the bass to resonate, so no matter what you put back there, it won't sound as good as the same speaker in a different location..
I am thinking of looking at the hatch lid as a possible speaker location. The ammount of air space behind the panel that covers the hatch may yield a better speaker location than the D pillar.
In the front, the dash speakers are supposed to be tweeters. There is no cross-over; they are wired in parallel with the door speakers, and have a "bass blocker" installed (Axial - NPO - [Non Polarized Capacitor])
Installing components, with a 6 3/4 woofer in the doors, 3.5" midranges in the dash and 1 to 2" directional tweeters at the top of each A pillar may be an alternative that would give good results. The internal space/volume in the door panel and the 6 3/4 speaker opening is a good combo for bass response up front.
