14AWG 4-Conductor Speaker Wire 250ft

This Monoprice 141387 speaker wire uses four conductors of 14AWG high-purity oxygen-free bare copper rated above 99.95 percent. The CL2-rated PVC jacket allows in-wall installation for whole-home audio runs. Each conductor carries colour-coded PVC insulation for quick polarity identification. The 250-foot length suits multi-room or custom-install projects.

Installers needing CL2-rated bulk cable

The four-conductor design lets you pull a single cable for stereo pairs or bi-wire configurations, reducing labour compared to multiple two-conductor runs. Buyers who only need a short patch cable or a pre-terminated assembly should look at something else. The bare copper construction also avoids the higher resistance of copper-clad aluminium alternatives.

Sustained signal integrity over long distances

Pure bare copper keeps DC resistance low so the amplifier sees a load close to the speaker’s impedance curve even at 76.2 metres. The 68 percent conductivity gap versus CCA becomes audible as frequency-dependent loss on extended runs. Colour-coded jackets maintain consistent polarity through the full pull, preventing phase errors that degrade imaging under continuous playback.

Questions about this item

What amplifier or receiver terminals are needed to connect this 14AWG speaker wire?

Any amplifier or receiver with standard binding posts, spring clips, or banana-plug terminals will accept the 14AWG bare-copper conductors.

Can this 4-conductor cable replace two separate 2-conductor runs to a pair of speakers?

Yes. The four colour-coded conductors let you run a single cable to two speakers, saving labour compared with pulling two 2-conductor wires.

How can I verify the polarity is correct after wiring the 141387 cable?

Each conductor has a distinct PVC colour; match the same colour to the positive terminal at both amplifier and speaker ends.
