the 1200.1 is only rated at 1000 watts at 2 ohms while the rockford is also rated at 1000 at 2 ohms(its rating of 1500 is at 1 ohm. I have owned amps from both companies and have been more than happy with both of em.Im really not biased towards either one but if you want more than 1200 at 2 ohms you shouldnt be looking at eithr oif these 2 amps. I just picked up a kicker 1500.1(1500 @ 2ohms)
