16 Gauge 4 Conductor Speaker Wire 1000 ft - In-Wall CL2 Rated

Our review finds this 16 gauge, 4 conductor speaker wire most useful for homeowners and installers who need long speaker runs or multi-conductor connections inside walls. The single biggest reason to buy is the cable's use of high purity, oxygen-free pure bare copper combined with a CL2-rated PVC jacket, which makes it a practical choice when in-wall fire safety compliance and reliable conductivity matter. In this review the cable proved easy to pull, offered good sound quality for most home theater setups, and carries Monoprice's lifetime warranty for extra reassurance.

Key Features

• Pure bare copper conductors: Each of the four conductors is made from greater than 99.95 percent oxygen-free bare copper for improved conductivity and long-term signal integrity.
• CL2-rated jacket: The white PVC jacket is CL2 rated so the cable meets common in-wall fire safety and insurance requirements for residential installations.
• Color-coded conductors: Individual conductors are jacketed in color-coded PVC to simplify polarity identification and make wiring faster and more reliable.
• 1000 ft spool: A full 1000 ft length reduces the need for splices on large installations and is convenient for long runs or multiple speaker locations.
• Lifetime warranty: Monoprice backs the cable with a lifetime warranty, which provides long-term protection and confidence in the purchase.

Who It's For

This cable is best for homeowners, AV installers, and hobbyists who run speakers, outdoor LED lighting extensions, or multi-zone audio systems where in-wall routing and fire safety compliance are required. It is also well suited to projects that benefit from a long uninterrupted length, such as whole-house speaker wiring or long-distance runs between equipment racks and speaker locations.

Those looking for ultra-thin cable for hidden runs in tight channels or who prefer pre-terminated speaker leads should look elsewhere. Also, if a buyer requires stranded CCA (copper clad aluminum) options for extreme cost sensitivity, this pure bare copper cable will be thicker and heavier than the lowest-cost alternatives.

Pros & Cons

Pros

• High purity oxygen-free bare copper for reliable signal transfer and improved audio clarity.
• CL2-rated white PVC jacket suitable for in-wall residential installs and insurance compliance.
• Color-coded conductors and a full 1000 ft reel make long runs and multi-speaker projects straightforward.
• Lifetime warranty provides long-term peace of mind on the cable purchase.

Cons

• Some users report occasional unraveling of the conductor strands when stripping, so careful handling and the right tools are recommended.

Our Verdict

For residential audio installs that require in-wall rated cabling, this 16 gauge 4 conductor speaker wire is a solid, value-minded choice: the pure bare copper conductors and CL2 jacket deliver reliable performance and safety compliance, and the 1000 ft spool and lifetime warranty add practical value for home theater and whole-house speaker projects.

Frequently Asked Questions

Is this cable safe for in-wall installation?
Yes, the cable is jacketed in CL2-rated PVC, which is intended to meet common in-wall fire safety requirements for residential buildings.

Can this wire be used for LED outdoor lighting runs?
Customers report using it successfully for outdoor LED light installations and long runs, though the jacket is PVC and outdoor exposure protection should be considered if not run in conduit.

How does the sound compare to cheaper CCA wire?
The pure bare copper conductors offer better conductivity than typical CCA wires, which generally yields improved sound quality and lower loss over long runs.
