We liked [Tom’s] advice from his old instructor: you aren’t really ever measuring a resistance. You are measuring a voltage and a current. With a four-wire measurement, one pair of wires ...

For longer distances over 100 feet or high-powered systems, 12-gauge wire is ideal, as it reduces resistance and prevents signal loss. If you have a higher end system, it's best just to use 14 or ...
