the bp600.1 will be fine for them. i actually used that amp to power a pair of 12w3s.

if you are going to use that setup, buying a 2OHM DVC or 4OHM DVC will not matter because that amp gives off the same amount of power @2OHM and @1OHM.

but to not stress that amp so much, run it @2OHM.

in order to get a 2OHM impedance with those subs and amp. get the D2 version of the W3s. this will be the dual 2OHM. wired the voicecoils on each sub in series. that will net a 4OHM impedance from each sub.

then take the +/- of the first sub, hook it up to the +/- of the amp. same for second sub.

that JBL amp is a monoblock, but has 2 sets of inputs. the amp actually wires it in parallel again. so the amp will see an impedance of 2OHM from the pair of subs.

with the right box, that setup is going to be sweet.:thumbup:
