SW16-300 - Premium True Spec 16 Gauge Speaker Wire 99.9% Oxygen-free Pure Copper – Super Flexible Jacket (300 Feet/spool)

The Echo PRO SW16-300 delivers 300 feet of true-spec 16 AWG oxygen-free copper speaker wire built for clean signal transfer and long-term reliability in automotive installations. With 111 individual OFC strands, this wire prioritizes conductivity and flexibility over cut-rate alternatives. The frosted red and black dual-jacket design makes polarity identification fast and error-free during routing.

• True-spec 16 AWG OFC construction — 111 strands of oxygen-free copper for maximum conductivity and corrosion resistance.
• 300-foot spool — enough wire for multiple installs or a full vehicle build without splicing runs together.
• Frosted red & black dual jacket — color-coded polarity identification reduces wiring errors during installation.
• Super-flexible outer jacket — simplifies routing through tight spaces, around corners, and behind panels.
• Corrosion-resistant insulation — protects conductors against heat, moisture, and the harsh under-dash environment.
• Patented modular spool and rack system — bearing-equipped spools slide in and out of racks that mount vertically, horizontally, on shelving, or on slat wall.
