No, i originally got the box with two 10 inch sdx pro audio subs, same brand as box. They were hitting pretty hard then i blew them within an 2 hours. I dont know if amp was too much for them or what. But same amp, same box, same wiring. Just different subs and they arent hitting barely at all. Ive heard good reviews about the Kicker CVR 10's so i dont understand this problem..
