wire it in the manner that skydive mentioned, that would be the best for your subs. Then get a MONO Amp that suits your needs. 1500W is a lot of power, but make sure you read the specs and you need 1500W @2 ohms!!! (which will be approx 750W mono @4ohms). What kind of box will you use? This is a factor that I would consider when choosing an amp.
