Alpine MRP-M650 vs. Alpine MRD-M605

What are the key differences between these amps??? im looking to upgrade from my profile california ap1000m. if i were to get either of these amps, they would power my single 12" type r at 2 ohms. im pretty sure the mrd is the better amp, but why? (im a n00b)

now im considering the alpine mrp-m850 (800w @ 2ohm) since alpine rates its amps at 14.4v and they will only be getting 12.5v. any thoughts?
