the hifonics 2010d "2000 rms" "cea" certified amp, has nothing on the Rockford T "1500". plan and simple, and all you have to do is spend an extra 150 or so, but its an investment. Im not saying the hifonics is bad, but in my case with the experience ive had, its worth the extra money. But hifonics for the money is still pretty good, just not as "clean" if you ask me.
