Right now, I'm gathering stuff for my new car. I am yet to have heard these subs, but I can't wait. I plan on running them off of a DD Z1A amp. I'm not sure what specs the box will be, a guy that works at DD is helping me build the box...i have 2 xxx 15s right now too.. what kind of box you have yours in?
right now mine are in 10 cubes @ 32 with 130sq of port.... i really need to decrease my internal volume though, my subs reach full excursion way before they should
