What happens when a speaker is wired with mixed polarity?
Any given input signal applied to a speaker will cause it to move either “in” or “out” creating sound. If the input applied to several speakers wired with mixed polarity, it puts them “out of phase” with each other, meaning that while one speaker moves “in” the other move “out” and therefore create distortions in the resulting sound.
How can I test the polarity of my speakers?
Now, look at the speakers cones closely. The current from the battery will cause movement in them, and you’ll will need to note how they move; the cone should go outward and then in. If it does this, the polarity is correct. However, if the movement is inward first, swap the wires around on the battery and look again.
What happens when you touch a polarity wire?
If your probe is touching a wire with an opposite polarity, such as the positive probe to a negative wire, you will get a negative numerical reading. Try switching which probe you’re using to get a positive reading instead.

Do you have to wire speakers with inverted polarity?
Even though the effects of inverted polarity are not noticeable so long as all speakers are wired the same way, it is a best practice to wire each speaker correctly when connecting to an amplifier. If you have labels on your wire, such as plus and minus symbols or red and black colors, it is very easy.
Is the polarity of a subwoofer always correct?
Even the speakers in subwoofer arrays, which sometimes contain speakers with inverted polarity to achieve better directionality, are usually wired with correct polarity. Any changes in polarity are almost always made in an audio console or amplifier DSP, rather than in the wiring of speaker terminals.
