I am getting (2) 15" Fi BL's and I will be running them off of a kicker zx2500.1 and I am going to get a large ported box but I don't know what size or tuning it will be. I was just wondering if this will get ridicuously loud while still sounding good because I want it loud as hell but also decently clean at the same time. I also was wondering if that amp is a good match for these subs. Thanx
