Product identity

Monoprice 121544 is a 16 AWG four-conductor speaker wire supplied on a 999.74 ft reel. The grey, burial-rated cable uses oxygen-free copper conductors inside a moisture-resistant polyethylene jacket with water-blocking tape.

Suitable installations

This wire suits outdoor commercial and residential runs where direct burial is required and four conductors are needed for speaker pairs. Buyers needing only two conductors for a single speaker or a different gauge should look at other options.

Capacity and headroom

The 1000 ft length provides ample cable for long perimeter or multi-zone layouts without splices. Oxygen-free copper keeps resistance low over extended runs, while the burial-rated jacket protects conductivity in wet soil conditions.

Questions about this item

What gauge speaker wire and amplifier terminals do I need to use with the 16AWG conductors?

The wire uses 16AWG oxygen-free copper conductors; ensure your amplifier or receiver accepts bare-wire connections or spade/banana plugs sized for 16AWG.

Can I run this 4-conductor burial-rated cable alongside existing 2-conductor speaker wire in the same trench?

Yes, the moisture-resistant polyethylene jacket and water-blocking tape are designed for direct burial, so it can share a trench with older 2-conductor cable without signal degradation.

How do I verify the 1000ft spool delivers the correct 999.74ft length and all four conductors are intact?

Measure the spool against the stated 999.74ft, then use a multimeter to check continuity and resistance on each of the four color-coded conductors from end to end.
