I've been running a pair of Almani S3 12"s for 2 years now, run them pretty hard off a Crossfire CFA602, and they've takin everything I've thrown at them. I also run Almani S5 5.25 comp's up front off a Crossfire CFA302, and they sound beautiful to me. I've been in and out of car audio for 20 years, installed, competed, etc., and my opinion, not the best I've ever had, but I firmly feel they are worth what I paid for and then some.
I haven't competed in several years now and no I can't tell you what kind of numbers they hit, but I can tell you they get pretty loud and shake the hell out of my car.
