The only part of my system that changed is the JL 13W7 was 86ed for 2 Image Dynamics IDQ 10's. They sound a lot better but the JL will be better for people that like obnoxiously annoying people. The Image dynamics that I got will not get as loud... but they are ridiculously small in comparison. They are for "sq".

Subs that I have had in the past.... MTX 6000, MTX 8000, Alpine R, Orion H2, MTX 9500, Memphis Mojo, Beyma Adire, JL 13W7 and now these.
