Yes, watch out for bad wiring! My father's 73 chevy caprice caught fire because of an amp that was wired in poorly. If you have a multimeter it shouldn't be too hard to find each speaker wire, as the speaker will show up with a certain impedance, Like 4 ohms of 8 ohms. Wiring it in phase is the real trick. For that you can only hope there is some sort of color code that the car came with, and there is a pretty good chance there is. I am assuming you are looking at the chopped radio wiring harness. There might be something like brown with a white stripe, and white with a brown stripe. It could also just be brown, and brown with a white stripe. You get the idea. They should all be wired in the same pattern, If they did not do this, then the some car manufactures just have better standards. I believe you can take a AAA battery and hit the two wires you know to be one speaker, and you should hear a pop from that speaker. I would be careful doing that if the speakers are really old, but it should be safe even then.
Its amazing what a 15 dollar multimeter can do in everyday electronics. My friend and I built an electric motorcycle, and obviously its very crucial for that, but I have used it for tons of things besides that. Especially old car wiring.
