American Bass has been building mainly Comp equipment since the mid 90's. Probably the most respected in the SPL lanes.
Some of the best Comp amps made. They do rated and then some. The guy claims these have been Modified by the owner. If he is serious, he should set them up and prove it on a clamp test. The subs are beasts, The amps are beasts. But $1500 is a lot of dough for modded equipment.....unless you run in a 250watt class...he he...7.5k out of a pair of 120 watt amps ain't too damn shabby. The subs are some of the best out there for spl...159.7 off 2 12's aint too bad either.
Price seems a little steep for used equipment. Says they were only used for 1 burp, but set a state record. Not likely that you would hit a score like that on the very first burp...
