14 AWG 500ft CCA Speaker Wire - CL2 In-Wall Cable for 70V Systems

In this review the Rockville RCC14-500-2 is evaluated as a practical choice for installers and DIYers who need a long, CL2-rated run of speaker cable. The bottom line: if you want a single 500 ft spool that covers multi-room projects and is certified for in-wall and ceiling use, this cable delivers reliable performance and easier routing thanks to a flexible PVC jacket. The review focuses on real-world installation, safety compliance, and audio compatibility for both 70V commercial systems and standard home theater speakers.

Key Features

• High-performance audio: 14 AWG CCA construction provides clear signal transmission for 70V lines and conventional speakers, making it suitable for background music and paging as well as home theater setups.
• CL2-rated safety: The cable is rated for in-wall and ceiling installations, offering reassurance for residential and commercial wiring runs where code compliance matters.
• Long 500 ft length: A single 500 ft spool reduces the need for splices and helps complete whole-room or multi-room installations without interruption.
• Flexible jacket: The PVC outer jacket bends easily for routing through studs, corners, and conduits, which speeds installation in confined or complex paths.
• Wide compatibility: Works with 70V commercial distribution systems and standard low-impedance speakers, providing versatility for different audio projects.

Who It's For

This cable is aimed at home theater enthusiasts, commercial installers, and DIY contractors who need long, continuous runs for offices, restaurants, or multi-room audio. The CL2 rating makes it a sensible pick when code-compliant in-wall or ceiling routing is a requirement.

Those who need oxygen-free copper conductors for audiophile-grade systems or need color-coded premium conductors for speaker bi-wiring should consider alternatives; this product is built with copper-clad aluminum to balance cost and length rather than prioritize high-end audiophile conductivity.

Pros & Cons

Pros

• CL2 safety rating allows in-wall and ceiling installations where code compliance is required.
• 500 ft spool eliminates frequent splices and is convenient for large or multi-room installations.
• Flexible PVC jacket makes routing through tight spaces and around corners straightforward.
• Compatible with 70V commercial systems and standard speaker setups for versatile use cases.

Cons

• Copper-clad aluminum (CCA) is less conductive than solid copper, which may be a limitation for very long runs at high power where voltage drop is a concern.

Frequently Asked Questions

Is this cable safe for in-wall installation?
Yes. It carries a CL2 rating, which is intended for in-wall and ceiling applications in residential and commercial environments.

Can I use this with 70V commercial speaker systems?
Yes. The cable is compatible with 70V systems as well as standard low-impedance speaker setups.

Will CCA perform as well as solid copper?
CCA provides acceptable performance for many installs, but solid copper has better conductivity and may be preferred for very long runs or high-power audiophile systems.
