I bought this back in 2011 along with one CVR 4ohm DVC 400 watt Sub. Like "peanut butter and jelly". This amp uses hardly any power and packs a big punch. I have it installed in my trunk(Honda Accord 4dr). After watching a video by Crutchfield about the best direction to face your sub for the most bass,which was facing the rear. I had to Dynomat the whole trunk. So much flex my rear view mirror was unusable. It never gets hot either. The bass was incredible. I used to have 2 10''JLw6's and 1000/1 JL mono block and the kicker hits just as hard and only a fraction of the cost of what I paid for my JL set up. I would recommend to all !!! I've had so many people ask me what I got in the trunk and when I tell them, its always disbelief. More bang for your buck.
Pros: Powerfull, reliable, and very small. Actual power rating certificate stamped at 496 watts in box.
Cons: Only stable at 2 and 4ohms. rather than that, none.
