Wirepath NST-182-PL-500-BLK 18AWG Audio Cable 500ft Black

Product Description

The WIREPATH NST-182-PL-500-BLK is an 18-gauge, 2-conductor non-plenum audio cable designed for in-wall and low-voltage audio distribution installations. Supplied in a 500-foot quantity, this cable is intended for background music systems, speaker runs, and structured wiring projects in residential and light commercial environments. The non-plenum rating means it is suited for standard wall cavities and conduit runs that do not serve as air-handling spaces. Low-voltage installers and audio-video integrators are the primary trades working with this product.

This cable is commonly used for distributed audio speaker wiring, connecting amplifiers to passive speakers, and whole-home audio system builds. The 18-gauge conductor size handles typical speaker-level signals across moderate to long runs without significant resistance loss. The black jacket blends into standard installation environments and is compatible with common termination hardware used in structured wiring panels and speaker connections.

Key Features

• 18-gauge, 2-conductor configuration for standard speaker-level audio wiring
• 500-foot spool length suitable for multi-room or multi-speaker installations
• Non-plenum (CM or CL-rated) jacket rated for standard wall cavity and conduit use
• Black jacket for low-visibility routing in finished environments
• Sold as a single unit (500-foot continuous pull)

Compatibility

Designed as a standard non-plenum 18-gauge 2-conductor speaker cable for use in residential and light commercial audio distribution systems where plenum-rated cable is not required by code.

Installation Notes

Installation should be performed by a licensed low-voltage technician or audio-video integrator in accordance with applicable NEC Article 725 requirements for Class 2 or Class 3 wiring. Verify with local authority having jurisdiction whether the installation location requires plenum-rated cable before using non-plenum jacketed wire in any air-handling space or return-air plenum. De-energize any connected amplifiers or source equipment before terminating conductors. Use a cable staple or J-hook rated for low-voltage wiring to secure runs and avoid sharp bends that could damage the jacket or conductors.
