Ok, I just got (2) 12" Kicker CompVR's and a Kicker ZX750.1 amp.

I am going to be installing them in my Ford Focus ZX3. I would like to get the most boom without completely horrible sound quality.

My First question is, Should I have a Ported or a Sealed Box? How much air space?

My Second Question is, Should it be facing towards the front or the rear of the car?

My Third Question is, If the Subs are 2-Ohm and 400w RMS and the Amp is 750w at 2-Ohms. Should I wire my subs Parallel (1 Ohm Load) or Series (4 Ohm Load)?

If they were wired for Parallel, would that mean I would be Getting 750w to each sub?
