Both very good amps when it comes to powering subs kicker and RF are on my top 5 list for amps. The kicker would preform very well and the it puts out around 900-1000 watts RMS when it gets going. The RF amp would also preform well and is underrated not over rated, the highest rms power ive seen was 1,355 watts. In my opinion id go for the kicker, it will last you all day and not get hot, RF amps have a rep. of over heating when the pressure is on. But RF puts out a good product and great power to go with it.
