C2G 100ft (30.5m) Bulk 18 AWG Shielded Speaker Wire, Plenum CMP-Rated

The C2G 29205 is a 100 foot reel of 18 AWG shielded speaker wire that meets rigorous plenum CMP requirements, giving installers a safe and code-compliant option when the cable must run through air-handling spaces. It arrives on a spool that feeds smoothly, so pulling the cable above drop ceilings or inside walls feels straightforward and predictable.

Inside the naturally colored jacket you will find two copper conductors, one red and one black, which make polarity checks quick at both ends of the run. Each conductor uses seven strands of 26 AWG copper, providing the flexibility you need to navigate tight corners without stressing the wire. A full foil shield surrounds the pair, and a stranded copper drain wire sits beneath the foil to give you an easy grounding point and to fight interference that can sneak into long audio lines. Footage markers printed along the jacket let you measure and cut precise lengths without reaching for a tape measure.

This cable works well in classrooms, conference rooms, houses of worship, restaurants, and anywhere that background music, paging, or high-fidelity audio is important. Integrators appreciate that the CMP and FT6 ratings remove the need for extra conduit in many commercial buildings, while homeowners gain the same professional-grade safety in whole-home audio projects. Whether you are wiring ceiling speakers in a lecture hall or connecting an amplifier to outdoor speakers on a patio, the durable construction and lifetime warranty provide peace of mind long after the installation is complete.
