Burial-rated 12 AWG speaker wire
This Monoprice Origin Direct Burial Series wire uses a moisture-resistant polyethylene jacket with water-blocking tape for long-term outdoor conductivity. It contains two colour-coded conductors made from 100 percent pure oxygen-free copper. The 1000 ft spool measures 304.8 metres and is finished in grey. Model 121547.
Suited for permanent outdoor speaker runs
The two-conductor design connects a single speaker per run, making it ideal for residential or commercial landscape audio. Installers needing four-conductor cable for speaker pairs or indoor-only installations should look at something else. Buyers who want pre-terminated ends or a different gauge will need another product.
Straightforward direct-burial installation
The tough outer jacket allows the cable to be laid in trenches without conduit, and the colour-coded conductors simplify polarity matching. What usually goes wrong is nicking the inner insulation while stripping the thick polyethylene jacket, which can create a short. Allow enough slack at each end to re-terminate if a conductor is damaged.

Questions about this item
Do I need any special connectors or tools to terminate this 12 AWG burial-rated speaker wire for my outdoor speakers?
The wire uses bare oxygen-free copper conductors with color-coded jackets; you can strip the polyethylene jacket and water-blocking tape, then terminate the strands with standard banana plugs, spade connectors, or direct screw-terminal connections using basic wire strippers.
Can I run this 12 AWG direct-burial cable in the same trench as the existing low-voltage landscape lighting wires I already have?
The moisture-resistant polyethylene jacket and water-blocking tape are designed for direct burial, but electrical codes typically require separation between speaker-level wiring and low-voltage lighting circuits; consult local regulations before sharing a trench.
After burying the 1000 ft reel and connecting my speakers, how can I verify the cable is performing correctly?
Measure DC resistance across each conductor pair with a multimeter — 12 AWG oxygen-free copper should read very low ohms per 1000 ft — then play audio and confirm clear, balanced sound from each speaker without hum or signal drop.
