wiring question

i am new to wiring up subs to get max power. i have a pair of audiobahn aw120t single 4 ohm subs and i have a 2 channel MA audio m300xe amp that i want to bridge to get a 4 ohm load which would be 500 watts rms. is this possible? if so what would the diagram look like? also there are two positive and 2 negative leads on the subs themselves do you run each pair on the same wire? im new so bare with me. any help would be appreciated.

also some info on building bandpass enclosures would be great too.
thanks

you cannot get a single 4 ohm load from to 2 4 ohm subs
