I am thinking about ordering 1 12" Rockford Fosgate RFR3112. It cost $259.00 and its 1000 watts RMS. Would it be worth the money considering a Rockford Power stage 2 sub is also 1000 watts RMS but cost $700.00. Also, would a Phoenix Gold Xenon X1200.1 x 1 Amp run well with it. I could get it from Online car stereo for $600.00. I am trying to keep everything under $1000.00. So tell me what you would do and would it out perform 1 mtx sub w/ 250 rms and 2 rockford p1 subs w/ 150 rms each.
