I'm pretty sure those subs have 4 ohm voice coils. So run everything in parallel. Run all the positive connectors to the + connector on the amp and do the same for the - connectors. That'll give you a 1 ohm load on the amp and it should handle it fine.
Alpine's can usually take a lot power and rockford amps can usually kick a lot of power and are bridgeable and stable at low impendance so bridge them like the other guy said -to- +to+ and to one speaker and parallel to the second and you'll be fine.
