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
The standard speaker wire colors for positive and negative terminals are typically red for positive and black for negative.
The speaker wiring diagram for a Saturn SL typically involves a standard configuration with four speakers: two front and two rear. The front speakers are usually connected to the head unit with positive and negative wires, often color-coded as follows: positive is usually white (or light blue) and negative is black. For rear speakers, the wiring colors can vary but commonly include gray for positive and brown for negative. Always refer to a specific service manual for detailed and accurate wiring information for your particular model year.
The new speakers come with un-stripped copper wires..... you need a pair of wire strippers.... i put in kenwood speakers and the size of the wire was 14 somethin. you would need to get a wire diagram for you car/truck to see the colors of the positive and negative wires. then look on the aftermarket speaker box to see which wire is negative and which one is positive.... After you would do all this, just match up negative to negative and positive to positive. simple as that. I'd recommend wire nutting the wires or electrical taping them... but DO NOT put all four wires together. that will mess your speakers' sound up completely. wire nut the positives together and then wire nut the negatives together.
