is this the Audiobahn AWC12T? they have dual voice coils.

if you wire each driver's voice coils together in series, then wire both drivers together in parallel with the amp, then that would present a 4 ohm load, so you'd need an amp that can deliver 1000W at 4 ohms

if you wire everything together in parallel, you'd present a 1 ohm load to an amp, so you'd need an amp that can deliver 1000W at 1 ohm.
