guys i dont want to get into a war over dc vs aq so im going to use a differnt example here .
i deal with alot of blown amps and i will compare a dd m4a and a 500.1 both the drive cards on the amps are inrerchangable as are the center caps and fets, both are the same type of board same build house. my ddm4a needed a terroid on the audio side and one from an american bass was used for 1 month and the amp perfromed the same .
im not saying which amp is best because its all about what flavor u like. dc,aq,sundown etc are all good amps
