SW18-500 - Premium True Spec 18 Gauge Speaker Wire 99.9% Oxygen-free Pure Copper – Super Flexible Jacket (500 Feet)

The Echo PRO SW18-500 delivers 500 feet of true-spec 18 AWG speaker wire built entirely from Oxygen Free Copper for clean signal transmission and long-term reliability. At 71 strands per conductor, it maintains excellent flexibility without sacrificing conductivity — a practical choice for full vehicle installations where wire routing matters.

• Pure OFC Construction: 71-strand Oxygen Free Copper conductors minimize signal loss and resist corrosion over time.
• 18 AWG / 500 ft Spool: Sufficient gauge and length for full-system installs including rear fill, door speakers, and component sets.
• Frosted Red & Black Jacket: Dual-color coding allows quick polarity identification during installation.
• Super Flexible Outer Jacket: Engineered for easy routing through tight spaces, door jambs, and under carpet without kinking.
• Vehicle-Grade Insulation: Jacket resists heat, moisture, and abrasion in the demanding under-dash and door panel environment.
• Modular Spool & Rack System: Patented bearing-equipped spool allows smooth, quiet wire dispensing and is compatible with Recoil's stackable rack system for wall, shelf, or display use.
