Monoprice 104037 12 AWG 4-Conductor CL2 Speaker Wire

The Monoprice 104037 Access Series speaker wire delivers audiophile-grade copper quality at an accessible price point. Each of the four conductors is made from 99.95% oxygen-free pure bare copper, which minimizes oxidation and resistance to maintain clean, accurate signal transmission over long distances. The 12AWG thickness provides a low-resistance path that is well suited for extended cable runs common in whole-house audio and home theater installations, helping to preserve bass response and overall fidelity even at lengths approaching 100 feet.

Designed with professional and DIY installers in mind, the cable features a CL2-rated white PVC outer jacket that meets fire safety standards for installation inside residential walls, ceilings, and conduit. Inside, four individually color-coded conductors make it easy to identify positive and negative leads for each channel, whether you are running stereo pairs to a single location or bi-wiring a speaker. The 100-foot continuous spool keeps cable organized and tangle-free during installation. While the wire requires separate connectors or bare-wire termination, its combination of pure copper construction, safety-rated jacket, and 4-conductor versatility makes it a practical choice for both new installations and upgrades to existing audio systems.
