you say they are about the same on "PAR" well then how come my audiobahn 12"s i used to have that were 700 watt rms each pushed fine with a 2 channel 800 watt rms audiobahn amp A8002T but yet I long before had them running on a pioneer 2 channel "1200 rms" Pioneer amp and the subs wouldn't even hit....they were ohm matched n all, now if it was a "PREMIERE" amp it woulda been just as good as the audiobahn but it's be double the price on ebay. Just think about that for a while
