Speakers are commonly employed in electronic siren circuits, public address systems, background music systems, whole-house stereo, and more. As such, when an installer carelessly connects two or more speakers together, damage can occur to either the speakers themselves or the amplifier they connect to.
To properly connect your speakers, dealers must learn how audio sound circuits operate, as well as how to calculate the overall resistance in a circuit. The basis for both is the ever-popular formula commonly referred to as Ohm's Law.
