that a good combo ? right now i got a 12 inch 2002 mtx audio road thunder with 125 watt rms and 800 x 2 2 channel rockford fosgate amp. my fuse just blew. I'm hearing rattling from the subwoofer. I got this installed at a car audio place. Should I be upset that he sold be a old subwoofer manufactured in 2002! and not a new mtx audio subwoofer from now or is it the same thing? I think subwoofer cant handle my amplifier could that be the answeR?
