Thanks for all the previous help. Right now I'm leaning towards using a Kicker Comp RT (12") in my CM. It's rated at 800 RMS (1600 Peak) and I am looking (as most of us are) for a quality, budget amp to power this. Any recommendations? I've come across Planet Audio, Power Acoustik, and a few other brands that seem reasonably priced. Also, any experience with this sub?
