Guess what I found in the dungeon?!? These came out of parts cars. I guess they were pretty top notch for late 80's early 90's. How terrible are these? Does anyone have ANY information about EITHER of these "power amps"? Anyone know what the heck a power amp is? I'm completely clueless, and before I go out and blow hundreds of dollars on an amp, can anyone offer some insight unto these pieces of metal?

Thanks!
