Monoprice Inc. 121549 Speaker Wire 16AWG 4-Conductor 250ft Gray Burial Rated

Outdoor Burial Speaker Wire

Monoprice 121549 is a 250‑foot spool of 16AWG four‑conductor speaker wire built for direct burial. The gray polyethylene jacket and water‑blocking tape resist moisture for long‑term outdoor runs. Pure oxygen‑free copper conductors carry signals to speaker pairs in residential or commercial installations. The cable is backed by Monoprice's Lifetime Warranty.

Capacity and Headroom

Four colour‑coded conductors let you wire two speakers per run, simplifying stereo pairs in gardens, patios or marine decks. The 16AWG gauge handles typical home‑audio power levels over the full 76.2‑metre length without excessive loss. Very long runs or high‑power professional systems may need a thicker gauge to maintain headroom. The burial rating ensures the jacket survives soil contact and wet conditions.

Upgrade Path

This spool replaces standard indoor speaker cable when the installation goes underground or through damp conduit. The jump is worth it whenever the wire must survive moisture, UV exposure or direct earth contact without conduit. Installers who only need a single‑speaker connection can choose a two‑conductor version instead. The lifetime warranty adds confidence for permanent buried infrastructure.
