hmmm not to be cynical but I can get the W0's online for around 80 bucks a pop, since the W0's are JL audios lowest sub in terms of performance, and putting 1200 watts to them is WAY to much, since there RMS rating is something like 200
But anyhow I digress, that setup is not worth 1200 maybe with a really nice custom box and all the wirering possibly... Albiet those are direct prices from wholesale dist.
Just my take on it
BTW I have a Cadence A7HC with 4 IDQ 12's SVC's
using a High to low level off the rear channel of the stock system
