to test for positive and negative, use a *AA* battery and touch the wires to each end of the battery terminals with a speaker connected. If the speaker pops outward, then you have the proper polarity, So whichever wire you touched to POS on the battery, is the POS speaker wire. If it pops inward, then swap the wires.
