My brother has the cc-1002 amp. IMO these amps are pretty crappy. I would stay away from these concepts. I'd put em in the catagory of amps like power acoustics and planet audio.
Reasons why I think they are crappy:
#1 half the weight of my JL (would probably means cheap internals and parts)
#2 It didn't even power my brothers 1 boston generator 12 all that well.
#3 it looked like they spent more money on the cosmetic then the design of the thing.
#4 like a lot of concept owners on other forums, this amp had burn smell to em when running. Supposidly some excess glue burning off they said.
#5 have you seen their video stuff? same generic stuff boss, PA, pyle and pyramid hock out.
Yea uoduck2k1? i read on a couple of forum and they said the new model concept 2400a was pushing 2400 watts and won some compitietion. they said the older model 2400D was crap. I have a punch power 1500bd and thinking of upgrading cause i think i'm running on 1 ohm with my 2 l7 right now, so my punch sometimes dies out on me cause it's not 1 ohm stable.
