well sir, that is not a crunch it is an MB Quart and just because it is manufactured by maxxsonics does not mean that it is of the same quality of the crunch, many people can vouch for the discuss line, except the few that got faulty DSC1500's other than that these amps are pretty decent, and even though i have not messed with the DSC2000 i have played with the DSC1500 and DSC480 imo they are great but to each his own.
