This will tell you how much speaker wire will be required for the job. Longer distances require a thicker wire because of the increased risk of a power failure. For distances between 80 to 200 feet (24.4 to 61 m), you need a 14-gauge wire. Distances greater than 200 feet (61 m) require the thicker 12-gauge wire. 12-gauge wire may be used in any speaker setup, even if the distance between the amplifier and the speakers is not terribly great. Some audiophiles swear by the extra quality and durability you get for the price. It never hurts to grab a little extra. You never know when you might need to extend the wires.
