Wirepath NST-164-500-PU 16AWG 4-conductor Audio Wire 500ft

Product Description

The WIREPATH NST-164-500-PU is a 16 AWG, 4-conductor non-plenum rated audio wire supplied in a 500-foot pull box. Built for in-wall speaker and audio distribution runs, this wire is designed for residential and light commercial low-voltage audio installations. The non-plenum PVC jacket makes it suitable for standard stud-bay and conduit runs where plenum-rated material is not required by code. Installation is straightforward for low-voltage technicians and integrators working on structured wiring, whole-home audio, or distributed speaker systems.

This wire is commonly used in residential new construction and retrofit audio projects where runs are routed through non-plenum wall cavities, conduit, or raceways. It is well suited for connecting in-wall and in-ceiling speakers to amplifiers or audio distribution equipment. The 500-foot length provides enough continuous run capacity for multi-room speaker distribution without mid-run splices. The pull box packaging allows for clean, controlled cable feeding during rough-in work.

Key Features

• 16 AWG conductor gauge supports longer speaker runs with reduced signal loss
• 4-conductor configuration allows a single cable to serve two speaker channels or one stereo pair
• Non-plenum PVC jacket rated for standard in-wall residential and commercial installations
• 500-foot continuous length minimizes splice points in multi-room audio layouts
• Pull box packaging supports clean, controlled feeding during rough-in installation

Compatibility

Designed for use in non-plenum low-voltage audio wiring applications including in-wall speaker distribution, whole-home audio systems, and structured wiring installations where a 16 AWG 4-conductor cable is specified.

Installation Notes

Installation should be performed by a licensed low-voltage technician or qualified integrator in accordance with NEC Article 725 and local low-voltage wiring codes. Verify that the installation environment does not require plenum-rated cable before routing through air-handling spaces. De-energize all connected audio equipment before terminating conductors. Avoid sharp bends or staple over-drives that could compromise the jacket or conductor insulation.
