How much electrical do I need?

I am shooting for a underdog type of setup as everyone around me hates on Pioneer.

I am looking at 4 x PRS-D5000SPL. They rate 1500W @ 2 -ohms. The subs will be two TS-W5102SPL, which have handle 2500W RMS. I figure I need an upgraded alt, two batteries, anything else?

big 3

i think he needs more like a actual 1/0 awg ground running from one of the bolts holding on the alternator, all the way to the back 2 batteries, on top of upgrading the big 3.....
