If you have a sound system at home that is not labeled for polarity, you have probably reversed the speakers’ wires by mistake. When that happens, you will get an audible difference in the quality of sound. But the question is, do car speakers have the same sensitivity to polarity?
Polarity of Soundwaves
Soundwaves make positive and negative pressures in the air. Positive pressure happens when soundwaves make a change above normal air pressure, while negative occurs when the change is below normal air pressure. The polarity of soundwaves, therefore, refers to the wavelength between the amplifier and the speaker.
Cables connecting the speaker and the amplifier determine polarity. Positive terminals should be connected from end to end; the same case applies to negative terminals. Swapping the connection will reverse polarity and distort sound waves.
Are Car Speakers Polarity Sensitive?
Car speakers are polarity sensitive. Connecting the cables in reverse will distort the sound waves and damage the quality of sound. Built-in car speakers might never have the polarity issue as the manufacturer will have already configured the cables correctly.
However, it is important to understand car speakers and their sensitivity to polarity as you might need to replace your car’s speakers.
