How to Size Speaker Wire

Wire comes in many different styles and sizes, but the most important consideration is the amount of current that will be carried by it, and that will determine the type of wire you'll need. The wire's size is indicated by gauge, with the most common being between 4awg and 22awg and commonly used for automobile speakers.
