its 37x2 at 4 ohms 75x2 at 2 ohms, same as the thunderpro amps, different heatsink, expect those numbers to be close to double that though, had a few in my days, GREAT amps, well woth the money he has them at
sorry guys, i bought this stuff back in high school and really didn't even know what i was buying then, so i appreciate the help from some of the other members. all i can really tell you is that these are in great shape and they really havent been used that much. thanks
