im pretty sure that the numbers that come on the amp arent there to tell you direct wattage. just check the back of it. also i used to play through a fender rumble dont recall the numbers on mine. it was a single 15 and that thing shook the walls. while peavey is a good name, its not as good as fender to...IMO. Good luck finding what you want.
