problem corrected, was bad connection on speaker

I just purchased this amp used, was cheap, I have no sound from it tho, I hooked up a 9v to speaker and it popped, so I know it works, I've taken it apart but now what lol. I have a multimeter which shows speaker wires have voltage from input to wires, any ideals?

Helloo, Ive recently bought a Crate gfx50TT and in need of a schematic of it if its available, I have power, but no sound, I tested the speaker which works, not sure if its all hooked up right. The person before me clearly took it apart so I wanna make sure its all back together right. Thank you
