the RF 360.2 will give off 360 watts @ 4OHM when bridged.
there are 2 types of 12" type Rs, they both are dual VCs.
SWR-1221D are the dual 2OHM
SWR-1241D are the dual 4OHM
you want the SWR-1221D, dual 2OHM subs, if you will be running a single sub to that amp.
then from there you wire it in series to acheive a 4OHM impedance from that sub, and bridge it to that amp.
have fun.
