lets see it really depends on how much $ you want to spend. I you don't mind spending I would say keep it all Rockford and do the power 800.2 that will make those subs bang. I am also partial to PPI they make great amps go with the pcx 1500 or the pcx 2200 or even look at the mtx 1000d those are really good amps but they are not cheep. they are about 650 on the low end. but with those amps you will get the full potential out of your subs.
imo, i would try to find a nice classD amp. i owned a Cadence a7hc amp. puts out about 1200 watts 1 ohm mono, or 900watts at 2 ohm mono. if i knew what ohm your subs were, i could supply some more info for ya. with classD they put less of a strain on your electrical system. hence, you could try out the amp/sub configuration and see if you need a cap. i noticed with my RF 225.2 amp i had, it drew a lot of power off my jeep cherokee. not to mention the facker got hot as hell!! the Cadence did not get warm at all, and did not dim my headlights like the RF amp did. if you do plan on getting a cap, and running more than 1000watts, get a 1.5F cap. hope this helps.
