18/2 500FT Speaker Wire CL2 Rated CCA - Easy Pull Box

In this review the 500ft 18/2 speaker wire from Cables Direct Online is evaluated for DIY installers and professionals who need a long run of in-wall low voltage cable. The main reason to buy is straightforward: it supplies a large, neatly packaged spool of CL2-rated 18AWG cable with sequential markings and an easy pull box that simplifies long runs. For anyone wiring home audio, LED lighting, or simple low voltage circuits, this cable offers a pragmatic balance of flexibility, length, and affordability.

Key Features

• Bulk length: The 500ft spool gives plenty of cable for multi-room audio runs or long low voltage circuits without frequent joins.
• CL2-rated jacket: The NEC CL2 rating and flexible white jacket make it suitable for in-wall residential and office installations.
• Easy Pull Box: Sequential markings every two feet and a lightweight box help control cable feed and measure remaining length quickly.
• 43-strand conductors: The multi-strand 0.16mm conductors improve flexibility and make the cable easier to route around corners compared with solid core wire.
• CCA construction: Copper clad aluminum conductors deliver a lower-weight, cost-effective solution for speaker and low voltage connections where pure copper is not required.

Who It's For

This cable is best for homeowners, AV hobbyists, and contractors doing long runs for surround sound, ceiling or outdoor speakers, LED lighting feeds, security sensors, or other low voltage needs where a CL2-rated in-wall cable is required. The long spool and markings are especially helpful for projects that require continuous runs without splicing.

It is not intended for high-current speaker systems where maximum conductivity is critical; users who require pure copper conductors for long, high-power audio runs should consider a dedicated oxygen-free copper option instead. Also, those who need outdoor-rated direct-burial cable should choose a cable designed for that environment.

Pros & Cons

Pros

• Good value for long runs thanks to the 500ft spool and affordable CCA conductors.
• Flexible CL2 jacket and 43-strand construction make routing and pulling easier in tight spaces.
• Easy Pull Box with sequential markings simplifies measurement and installation planning.

Cons

• CCA conductors are less conductive than pure copper, which can matter for very long or high-power speaker runs.
• Some users report variable long-term durability, so applications demanding heavy-duty longevity may prefer copper alternatives.

Specifications

Our Verdict

This 500ft 18/2 CL2 speaker wire is a practical, cost-effective choice for in-wall audio and general low voltage installations where long continuous runs are needed. The flexible jacket, easy pull box, and strand construction make installation easier and the product represents good value for typical home theater and lighting projects, though installers needing maximum conductivity or extreme long-term durability should opt for pure copper alternatives.

Frequently Asked Questions

Is this cable safe for in-wall use?
Yes. The cable has an NEC CL2-rated jacket suitable for residential and commercial in-wall low voltage installations.

Can I use this for LED lighting and security sensors?
Yes. The 18/2 construction and CCA conductors are appropriate for LED lighting, motion sensors, and security devices connected to a control panel.

Is copper recommended instead of CCA?
For high-power audio or very long runs where conductivity and longevity matter most, pure copper wire is preferable; however, CCA is an economical option for many typical installations.
