In-wall rated 4-conductor speaker wire

This 100-foot spool of 18AWG wire uses oxygen-free copper rated at 99.95 percent purity. The white CL2 jacket meets residential in-wall fire-safety requirements. Four conductors let you run a single cable for bi-wire speakers or two stereo pairs. Pure bare copper avoids the higher resistance of copper-clad aluminium alternatives.

Replacing thinner or CCA cable

Thinner gauge or copper-clad aluminium wire adds resistance that can alter speaker impedance and degrade sound. Stepping up to 18AWG oxygen-free copper reduces that loss, especially on longer runs up to the full 30.48 metres. The jump is worth it when you are pulling wire through walls and cannot easily replace it later.

Check your run length and termination needs

Measure each speaker run to confirm the 100-foot length covers every path with slack for connections. Verify that your amplifier and speaker terminals accept bare 18AWG wire or plan for suitable connectors. Ensure local building codes accept CL2 rating for the intended installation.

Questions about this item

Will the 100 ft spool of 18AWG 4-conductor wire fit through standard wall cavities?

The CL2-rated white jacket is approved for in-wall use in residential buildings, and the 100-foot length on a spool lets you pull only what each run needs.

How do I terminate the four oxygen-free copper conductors without shorting them?

Strip each of the four 18AWG conductors separately, keep the polarity-marked pairs together, and secure them under the corresponding speaker or amplifier terminals.

When should I replace this in-wall speaker wire?

The oxygen-free 99.95 percent pure copper resists oxidation, so replacement is only needed if the CL2 jacket is damaged during renovation or if a conductor is physically severed.
