i have the xeon 1200.1 running 3 zr 12dvc pg subs in a ported box. the subs vc are wired series and the subs are peralleled to get 2.6 ohms and let me tell you it hits so hard ive acctually broken a window. i had problems at first with the amp shutting down, but to fix this i went with 1/0 guage wire and a 3 farad cap and have had no problems since. i do suggest getting a pro line driver, it allows your amp to not amplify the the rca signal and it sounds alot clearer the amp runs at decent temp. i replaced my ms2250 with the xeon 1200.1 and am glad i did. i never personnally used the kicker amp but i also havent heard a system as loud as mine in my area so i just stick with what works
