I am starting to debate what amp I should go with, Rockford Fosgate t40001bd, Autotek MM4000, or IA40.1. Pricing doesn't concern me that much, I am more looking for a "which would be a better amp to go with" I am guessing it to be in this order, but am not 100% IA40.1 T40001bd MM4000.1D Thanks I was lookin more for the IA, cuz they aren't as popular as the forgate, but they are becomming harder n harder to find.
