I an going to buy 2 sets of the Rockford fosgate power t2652-s component system (total of 4 mid bass speakers and 4 tweeters) and I need help deciding on a 4 channel amp to get for them. The 2 I'm looking at are listed in the title above. I am looking for SQ! Which amp would be better for SQ? And also the JL is a class D amp which means that it has very good efficiency but lacks a bit in SQ but since it is a full range amp it shouldn't be too bad. The ROCKFORD FOSGATE is a class AD amp which means that it has the efficiency of a class D amp and the SQ of a class A amp. So which amp should I get for SQ? And what's better JL's class D or RF's class AD?
