GearIT 12/4 Speaker Wire 250 ft - OFC Outdoor Direct Burial

In this review the GearIT 12/4 Speaker Wire (250 ft) is evaluated for home theater, in-wall, and car audio use; the bottom line is that this cable is for anyone wanting a durable, high-conductivity run with flexible multi-conductor wiring. The reviewer found the oxygen-free copper construction and UL CL3 rating to be the single biggest reasons to choose it, since those attributes deliver improved conductivity, corrosion resistance, and safe use for direct burial or in-wall routing.

Key Features

• OFC Oxygen Free Copper: Provides higher conductivity and clearer transient response for amplifiers compared with typical CCA wire.
• 12AWG 4-conductor design: Lets you run bi-amped or stereo pairs in a single jacket, simplifying multi-speaker and car audio installs.
• 250 ft length: Covers long runs for a whole room or outdoor speaker layout without splices, reducing signal loss points.
• UL CL3 and CL2 rated: Approved for in-wall installations and built to comply with fire-safety requirements for home theater wiring.
• Outdoor direct burial ready: Durable jacket and construction allow burial in ground without conduit for landscape or patio speakers.
• Stranded conductors: Flexible for routing and easy termination with banana plugs, spade tips, or bent-pin connectors.

Who It's For

This cable is best for homeowners wiring a dedicated home theater, builders installing in-wall runs, or car audio enthusiasts who want a premium OFC conductor for lower resistance and better long-term corrosion resistance. Installers who need a single jacket containing four conductors will appreciate the organizational and routing advantages for multi-channel or stereo speaker pairs.

Those who only need very short runs or who prioritize the lowest cost regardless of conductivity may look for thinner, cheaper alternatives. Also, if an installation requires LSOH or other specialty jacket materials not mentioned here, verify compatibility before purchase.

Pros & Cons

Pros

• OFC construction gives improved conductivity and reduced corrosion risk compared with CCA options.
• UL CL3/CL2 rating and direct burial capability make it versatile for in-wall and outdoor installs.
• Four conductors in a single 12AWG jacket simplify multi-speaker or bi-amp wiring runs.
• Long 250 ft spool eliminates the need for joins on larger projects, saving labor and signal integrity.

Cons

• Heavier 12AWG cable can be less flexible for very tight bends or cramped conduit runs.
• Specification set does not list jacket material details, so confirm environmental exposure limits for extreme conditions.
