Okay. I say go with the B2. It's **** and I haven't heard people complain about anything B2 yet. I don't have their amps, but I do have their woofers. I can't recommend DD - if it craps, they blame it on you. I've talked to dealers who stopped carrying their products due to warranty issues as well. I like mine now that it works, but if it breaks - don't wish that upon you. Also, whatever the hell it is they do to fix it - seems like BS. As for CT sounds, their named has been dragged through the mud. I don't have personal experience with them, but honestly there are too many other options to even concern yourself with them. Soundqubed is cheaper option, B2 is sexier. Go to ssaudio.com and look at DC, ampere audio, and IA. I'd personally go with B2 or IA - just because of the looks. Performance and reliability wise, from what I've read, they are similar.
