Okay, won't tell you to get the W3's but I will tell you to skip the California Profile amp. You're going to blow your subs with that amp. Not overpower, but underpower them. Profile stuff is notorious for having severe underpower distortion spikes and they will pop a sub ten times faster than a sub that is "overpowered" but clean. The best way to do it is to take the RMS rating of the sub, put an amp on it that is over the RMS rating, then turn your gain down and put your bass in the negative numbers on your head-unit. It will be solid, full, long living bass rather than loud, distorted, burned out voice-coils in 3 months bass
