This listing is for a 10FT Section of True 18 Gauge AWG wire. Memphis Audio uses pure oxygen-free copper wire to provide maximum conductivity for your system. Copper wire is more expensive but it is capable of delivering more power to your amplifier and work under more extreme conditions. Under powering is a leading cause for amp failure, so Memphis Audio prides itself on using 100% copper for optimum performance. As an added feature, Memphis Audio coats their copper in a tin metal alloy. The natural corrosion resistance of copper is increased and helps the wire to perform in humid, wet, and high-temperature environments. Memphis Audio's remote wire allows a clean effortless signal to flow directly to your systems components.
