Southwire/coleman Cable 94603-66-18 18/2 Speaker Wire 500 Ft

Product Description

The SOUTHWIRE/COLEMAN CABLE 94603-66-18 is an 18 AWG, 2-conductor speaker wire supplied on a 500-foot spool. The clear, polarized jacket allows quick visual identification of polarity, reducing wiring errors during installation. Rated for low-voltage audio signal transmission, this wire is a standard choice for residential and light commercial speaker runs. Electricians, low-voltage technicians, and A/V installers use this product for distributed audio systems, in-wall speaker drops, and surface-mount speaker connections.

This wire is suited for residential and light commercial audio installations where a 500-foot continuous run reduces the need for mid-run splices. The polarized clear jacket simplifies conductor identification across long pulls. Typical applications include whole-home audio distribution, home theater speaker wiring, and commercial background music systems. The 18 AWG gauge is appropriate for moderate-length speaker runs at standard impedance loads.

Key Features

• 18 AWG, 2-conductor construction for low-voltage audio signal transmission
• Clear polarized jacket for easy identification of positive and negative conductors
• 500-foot spool reduces splice points on long runs
• Spooled packaging allows controlled, tangle-free dispensing during installation

Compatibility

Designed for use with standard 8-ohm and 4-ohm passive speakers in residential and light commercial distributed audio systems.

Installation Notes

Installation should be performed by a licensed electrician or qualified low-voltage technician in accordance with NEC Article 725 for Class 2 and Class 3 wiring. Confirm the wire rating is appropriate for in-wall or plenum use before concealing inside finished assemblies, as additional jacket ratings may be required by local code. De-energize all associated amplifiers and audio equipment before making terminations. Observe polarity markings consistently at both the amplifier and speaker terminals to avoid phase cancellation.
