The MA Audio subs will be much much much cleaner. Hifonics stuff is not as nice as MA Audio stuff. The MA Audio amps don't run near as hot as the Hifonics one. My friends have had all types of Hifonics stuff and they're all excited to show it off. I listen to it, tell them its nice, sit them in my ZX3, and then watch them frown when they realize their stuff is not near as clear as mine. Hifonics may be a bit louder, but pound for pound, the MA Audio stuff is cleaner and more reliable.
