C2G 25ft (7.6m) Bulk 18 AWG Speaker Wire, Plenum CMP-Rated

The C2G 40534 is a 25-foot speaker wire that gives installers a straightforward, code-compliant way to run audio lines in walls, ceilings, or air-handling spaces. Because the jacket carries a CMP plenum rating, the cable meets strict fire-safety requirements and can be installed without additional conduit, a benefit that saves time and reduces material costs.

Inside the jacket, you will find two conductors that use 18 AWG stranded copper. Each conductor is built from seven strands of 26 AWG wire, a construction that allows the cable to bend easily around corners while still delivering clear, full-range sound. The red and black insulation on the individual conductors makes polarity checks quick and virtually error-proof.

C2G includes printed footage markers along the entire length, so an installer can see at a glance how much wire remains on the reel and cut precise runs with minimal waste. For short to medium audio paths—such as the distance from a rack-mounted amplifier to ceiling speakers in a classroom, meeting room, or retail space—this 25-foot section covers common layouts without leaving you with excessive slack.

Whether you are a professional AV contractor working under tight building-code requirements or a facilities manager adding background music to an office, the 40534 provides a reliable, ready-to-pull solution that keeps installations clean, safe, and easy to service.
