I am putting 4 speakers in an indoor riding arena. High fidelity is not important. The goal is to have a system that can be turned up loud without distortion.

The distance from the amplifier to the most remote speaker will be about 250 feet. The distance to the closest speaker will be about 50 feet.

Best Buy has rolls of large-gauge speaker wire, but it is pricey. Do I really need that fancy wire? This system is not for audiophiles. It is for people who ride to music and want to be able to hear it when their horses are far away from the speakers.
