Wiring inside a box

I have a simple question, what type wires do I need to get to wire inside of a box for my subs.

If it matters, I have 2 15" aw150q audiobahns that do 600watts RMS and I have a 1200 watt max a/b mosfet amp running to it

12-14 gauage should be fine

not to be a moron, but seeing as how I have never done this, is their a difference between speaker wire, and power wire or any other type?

no, not really ..... wire is wire. Generally, more expensive wire has a higher number of strands (which are relatively small), so it bends easier.
