This 2-Channel 5-Wire 18AWG OFC Speaker Cable is made to keep your speaker install as simple as possible. The 5-Wire allows you to run one wire group together, from your dash to your speaker amplifiers in the rear of the vehicle. This grouping of wire also includes a single 5th wire for your remote turn-on running to the amplifier. The wire is always made with oxygen-free copper that meets the American Wire Gauge Standards.
