Overview

The Monoprice 141384 is a 100-foot spool of 12AWG, 4-conductor speaker wire designed for permanent audio installations. Built with oxygen-free pure bare copper conductors, it delivers low-resistance signal transmission that preserves audio clarity across the full length of a run. The CL2-rated PVC jacket meets fire safety standards for installation inside residential walls and ceilings, eliminating the need for separate conduit and simplifying the wiring process for whole-home audio systems, home theaters, and multi-room speaker setups.

The 4-conductor configuration is what sets this cable apart from standard 2-conductor speaker wire. Each cable carries two independent pairs of conductors, allowing a single run to service two speakers — ideal for ceiling speaker installations or distributed audio zones where running multiple cables would be impractical. The 12AWG gauge is heavy enough to support long runs with minimal signal degradation, making it suitable for larger homes and commercial spaces. The black PVC jacket is durable and clearly color-coded internally to simplify identification during termination. While the thicker gauge requires a bit more effort to strip, bend, and route compared to lighter wire, the trade-off is a robust, long-lasting installation that maintains audio performance over time.

Key Features

Features 4 conductors made of high purity (greater than 99.95 percent pure), oxygen-free bare copper.

Pure Bare Copper is a superior conductor to the copper clad aluminum (CCA) conductors used in most other inexpensive speaker wire.

Using Pure Bare Copper speaker wire ensures that the total load put on the amplifier remains as close as possible to the impedance curve of your speakers.

Each conductor is jacketed with color-coded PVC for easy polarity identification.

CL2 rating indicates that the cable complies with fire safety and insurance requirements, making it safe for use inside the walls of residential class buildings.

Frequently Asked Questions

The CL2 rating indicates that the PVC jacket meets fire safety standards for in-wall installation, so it can be safely run inside walls without the need for additional conduit in residential settings.
The 4-conductor design allows you to run a single cable to power two separate speakers — one pair of conductors per speaker — which simplifies wiring in whole-home audio, ceiling speaker, and zone audio installations.
Oxygen-free pure bare copper reduces oxidation and corrosion over time, maintaining consistent signal conductivity and audio clarity throughout the life of the installation.
Yes, 12AWG is a heavy gauge that minimizes signal loss over longer distances, making it well suited for runs up to 50 feet or more per speaker without noticeable degradation in sound quality.
The CL2-rated PVC jacket is designed for in-wall use. While it provides some protection, it is not rated for direct outdoor exposure or burial, so outdoor runs would require additional conduit or weather-rated protection.
