What are the colors for positive and negative on the speakers of a 1995 Cavalier?

The voltage in speaker wire is too small to cause harm. Plug the two wires in. If the speakers work the wires are correct. If the speaker doesn't work try them the other way.

ANSWER voltage does not cause harm no matter how high. amperage is what causes harm. speakers will work like a light bulb either way. positive to negative or negative to positive. with sub-woofer you can tell if it is right, the sub should pull inward on deep base . I believe cavalier rear speakers are hooked in series positive in one speaker, negative of that speaker to positive of the other speaker, and neg of that speaker back to stereo
