14/2 Speaker Wire 14AWG 500ft - OFC Oxygen Free Copper In-Wall CL2

Our review of this 14AWG 2-conductor speaker wire finds it best suited for homeowners and installers who need a long, reliable run of cable for in-wall audio or car speaker upgrades; the single biggest reason to buy is the use of high-strand 99.9% OFC oxygen free copper conductors that improve conductivity and corrosion resistance compared with CCA alternatives. The 500 ft spool, CL2 in-wall rating and sequential markings make it a practical choice for measured installs where consistent signal transfer and safety are priorities.

Key Features

• OFC Oxygen Free Copper: High-strand 99.9% oxygen free copper conductors provide improved conductivity and reduced signal loss over long runs.
• CL2 Rated Jacket: The UL CL2 rating allows safe in-wall routing for home theater and built-in speaker installations.
• 500 ft Spool: A full 500 ft spool is convenient for whole-room or whole-house installs without splicing multiple reels.
• High strand count: Fine 0.16 mm x 105 strand construction keeps the cable flexible for routing while maintaining consistent electrical performance.
• Color-coded conductors: Clear polarity identification simplifies hookup to receivers, banana plugs, spades or bare wire connections.
• Sequential markings: Printed markings at 2 ft intervals give accurate measurement and help avoid surprises during installation.

Who It's For

This cable is ideal for DIYers, custom installers and anyone wiring a home theater, multi-room audio or car audio system who wants better conductivity than CCA wire. The CL2 rating and long spool length suit in-wall runs behind walls and through conduits where safety and uninterrupted length matter.

Those who should look elsewhere include buyers who only need a short patch lead or inline speaker jumper, or installers requiring specialized shielded cable for high-interference environments; this product is unshielded speaker wire designed for general audio/installation use rather than niche studio or RF applications.

Pros & Cons

Pros

• OFC construction provides improved conductivity and corrosion resistance versus CCA alternatives.
• CL2 in-wall rating makes it suitable for permanent home installations.
• 500 ft spool with sequential markings is convenient for long runs and precise measuring.
• High strand count keeps the cable flexible and easy to route in tight spaces.

Cons

• Unshielded design is not intended for environments with significant electromagnetic interference.

Our Verdict

For homeowners and installers needing a long, safe run of speaker cable, this 14AWG OFC CL2 wire offers a solid balance of performance, durability and value; the oxygen free copper and full 500 ft spool reduce signal loss and simplify installs, making it a sensible upgrade over CCA wire for most residential and car audio projects.

Frequently Asked Questions

Is this speaker wire safe for in-wall installation?
Yes. The cable is UL CL2 rated, which is the standard certification for in-wall low-voltage installations.

Can I use this with banana plugs or spade connectors?
Yes. The color-coded conductors and stranded construction are compatible with banana plugs, spade tips, bent pins or direct bare wire terminations.

Will OFC make an audible difference over CCA?
OFC offers higher conductivity and corrosion resistance, which can reduce signal loss on long runs and is generally preferred for clearer, more reliable audio delivery.
