wired confusion

i might get an amp for free, it is for my car, not my room. hope someone can still help. it is an old McGohan 100 Watt Booster Amplifier Model MS-1001. The hookups on the back are like this: GND-4OHM-COM-8OHM-25V-70V. These all have screws underneath and GND and COM are connected with a wire. Then there is: BOOSTER IN and BOOSTER OUT audio jacks. Then is says 600 OHM LINE GND with three screws underneath. Can anyone help with how i should wire this.
The speakers i want to hook up to it are two old Fisher 50 watt component speakers with a 3 in tweeter, 4 in midrange, and 10 in woofer.

I looked it up ... it PA amplifier (1 channel). And designed to run off of 110V AC. The 25V and 70V are for matching transformers ...... give it up and buy a REAL car STEREO amp

You mean your room not your car? This is a home stereo type amp, not car audio

Ground and Common are the same thing, Booster in/out is audio in/out from your stereo or whatever...

What impedence/Ohm rating are the speakers, this will determine how you wire it up.

But basically, ground out Gnd, leave it connected to Com, and follow whats above, 4 Ohm speakers to 4 Ohm, 8 Ohm speakers to 8 Ohm
