Most of the guys who run the GP 3000d pro on term pro have a signature picture of the Crunch gear..they also have won or placed VERY well in their given classes...Not hard to find them if you look. Look for Team Live Wire, Gavin, Iggster, more than that use them and seem to more than just like those amps. Too say one amp is better depends on where you place your value as both sundown and the gp3000d pro work and do well. If you are starting from scratch though on a limited budget you can get a gp and at least a good portion of a good battery/electrical for your system which amps of this size need.
