    Any help would be greatly appreciated! I brought home my new to me vintage Audio Pro B1-45 and pulled the amp section off to check the foam roll condition, the foam had been replaced but as I was taking the amp off the speaker wires popped off. There is a post marked speaker positive but there are two others. There is continuity between the the other two to ground.
    Any thoughts?

    Yes they are connected by my continuity test. I’m probably overthinking this because I’m a novice!

    The other two are both ground. If you were to turn the circuit board over, you would see that they are both soldered to the same ground connections. Use the positive and either negative. Your choice.
