Reversing speaker wire polarity is a common audio error. This action is known as making the speaker “out of phase,” and results in audio oddities. Although this is not dangerous to a speaker or amplifier, proper power delivery and speaker response is not possible with reversed speaker wires.
How do I know if my speaker wire is pre wired?
