im gunna go out on a limb and say those sony's wont handle the power they say they can
but if you want a decent amp.
i have a 1100 watt @ 1 ohm tsunami amp.
however, you would have to figure out what voice coil config you have on those subs so you could take advantage of 1 ohm.
i would reccomend
JBL bp1200.1
new phoenix gold amps (1200 watts @ 1-4 ohms)
directed audio
viper (more expensive directed audio amps)
