Subwoofer question?

Will a Boss GT580 be a sufficient enough amp to power these Rockford Fosgate PL2-212 becuase if it is then I'm gonna buy it?

any amp will do a good job it all depends on how much power you want to send to the sub without exceeding it's RMS wattage by to many watts. Too many watts will blow the wiring in the sub itself, but staying within the RMS will render your subs unblowable unless something catastrophic happens that I have never encountered.
