As I've been looking for a good single 10 or 12 to put in the Z, it just seems that the JL subs are twice the cost of other great subs, like the Image Dynamics and RF subs, and arguable not even as good.

I'm read good things about the IDQ line from Image Dynamics and the Power series from RF. There are honestly a dozen great choices out there for clean base. The headache you get from some base may be the amp and enclosure, more than the sub itself.
