DS18 SW-OFC16GA-500RB OFC 16-GA Speaker Wire 500 Feet

Your sound system is only as good as its connections. Guarantee stable connections between all your systems components by using DS18’s Premium High Performance Ultra Flex Speaker Wire.

The integration of Oxygen-Free Copper in our speaker wires allows our wires to run cooler during longer jam sessions, increases the wire’s resistance to negative electrical effects, and protects your wires from corrosion due to their decreased oxygen content.

This black and red jacket covered 16-Gauge speaker wire gives your system the optimal current flow needed to charge your system to the MAX!
