i run an MA audio amp to my 12" hcca....thats one power hungry sub and the amp doesnt even get hot....ever...i've never felt it hot and i've put it through some pretty good sessions...
Memphis is a good company...i would put them along the line of Kicker.
I have always liked Memphis, even though i have never personally owned them. I have installed quite a few Memphis subs and amps though. As a matter of fact, 2 weeks ago i built a 4cu ft ported box for 2 12" memphis subs. I installed them in a buddy of mines truck...they sounded pretty darn good.
Lol, MA audio is crap. And yes I have heard it personally. 2 15's run off a 1000 watt MA audio amp, and it sounded like junk. Wasn't even that loud for 2 15's and 1000 watts. I would place MA audio even below Audiobahn personally.
