Don't take this the wrong way.
It sounds like you don't know what you want!
What do you actually want from you system?
Is this a quick throw it in the boot jobby or are you looking at building an install over time?
I wouldn't go with pioneer in all fairness. Have a look into spl dynamics not splx, AA, FI, Orion.
Two twelves ported would want at least 4cu ft after displacements. If your thinking of running 2k rms you'll want more batteries. Lots of 0awg and a fully sound deadened car ideally.
Plan your install out before you buy any kit otherwise it'll cost you double and take twice as long. Trust me I've got first hand experience with that.
