Ahh no you won't get 5x9's in the back. if anything they will be 6" again, like the front.

and i would stay away from Infinity amplifiers, I bought one recently and it sounded like ass, absolutely no depth to the sound, I immediately replaced it with an Alpine.

I wouldn't trust those numbers... they don't add up.

I don't know if you will care but

V_max=√2V_RMS

Not one of those match up...

Anyway. The "Rockford Fosgate RF-T1692C" would be a good go. Because they are a oval the sound waves produced can be quite testy at times. The ridged structure should reduce this resonance though

When matching a amp to speakers find a corresponding value by rule of thumb. RMS_amp=RMS_Speaker or the same with peak to peak.

One last point you will have a lot of mid range... The natural frequencies are around 1900Hz for the two loudspeakers. A 12" has a natural frequency of around 1100Hz

This probably didn't help you but it sure helped my physics study.
