Answer 1

If you are preparing to hook up wires to the amplifier and you are not sure which is negative and which is positive, take a 9-volt battery and tap the speaker wire to the positive terminal of the battery. If the speaker first moves forward (or out), then you have touched the positive lead of the speaker to the positive terminal of the battery, and the remaining wire is negative.
