Scosche EFXS9WC18-250 250 ft 18 AWG True Gauge 9 Conductor Copper Speaker wire
Not so long ago all car audio manufactures used only copper and used American true gauge standards (AWG) to make speaker and power wire, that is until the price of copper went up. Today most companies cheat. They make there wire with an aluminum core with just a copper coating and make up the gauge size.
What’s the Problem with Aluminum Wiring?
From the mid ’90s , aluminum wire often replaced copper as a less expensive alternative. Aluminum, however, is not a direct replacement for copper since each type of wire has different physical properties. Aluminum’s properties proved problematic for reasons no one had anticipated. What you need to know is the following: with aluminum wiring it is possible that, over time, a high resistance connection and/or arcing could develop somewhere in the electrical system, resulting in a connection that gets very hot and increases risk of fire. With the extra resistance amps run hotter and produce less power. Your sound quality suffers as well as the life expectancy of your equipment.
This 4-Channel 9-Wire is made to keep your speaker install as simple as possible. The 9-Wire allows you to run one wire group together, from your dash to to your speaker amplifiers in the rear of the vehicle. This grouping of wire also includes a single 9th wire for your remote turn-on running to the amplifier.
Scosche wire is always made with oxygen-free copper that meets the American Wire Gauge Standards.
