I have the 06 model bxi1606D and i love it. I am running it at 2 ohms now and its putting out 800 rms, and it gets pretty loud with two 12's. The only thing i dont like about it is that the casing is metal, and i had the car on while i was doing some work on it and it shorted out my subwoofer out leads because i accidentaly touched the casing. If you always work with it with the car off and battery unplugged its fine though. I would reccomend it.
