16AWG 4-Conductor CL3 Speaker Wire

This 250ft reel of 16AWG four-conductor speaker wire uses pure bare copper conductors rated above 99.95% purity. The CL3 jacket meets in-wall fire safety and insurance requirements for residential installations. Colour-coded PVC insulation on each conductor simplifies polarity identification during long runs.

Installers needing in-wall rated multi-room cable

Suited for whole-home audio, distributed speaker systems, or any run that must pass through wall cavities under code. Not for buyers who need heavier gauge wire for very long low-impedance runs, or who require pre-terminated connectors for plug-and-play convenience.

Pure bare copper versus copper-clad aluminium

The bare copper conductors deliver roughly 68% better conductivity than copper-clad aluminium alternatives, keeping total cable resistance below the 5% threshold that affects speaker impedance curves. Colour-coded jackets reduce wiring errors, while the CL3 rating allows legal in-wall placement without additional conduit.

Questions about this item

What amplifier or receiver terminals accept this 16 AWG pure bare copper wire?

Any standard binding posts, spring clips or banana-plug sockets that take 16 AWG bare wire will work; strip the colour-coded PVC to expose the copper.

Can I pull this CL3-rated 4-conductor cable through walls that already contain older speaker wire?

Yes, the CL3 jacket meets in-wall fire-safety requirements and can share a cavity with existing cables of any gauge.

How do I verify the wire is performing correctly after installation?

Measure DC resistance per conductor with a multimeter; it should be very low for 16 AWG pure copper, confirming continuity and correct polarity via the colour coding.
