2 12" Kicker c12 comps and 1200 W amp....ohms question?

this is my first set up and i was wondering if i should rewire it to lower it to 2ohms. they are 4 ohms bridged.my amp is stable from 2-8 ohms. and what really does parallel wiring do? just give the subs more power from the amp?the amp is 1200w peak
