Monoprice 116174 speaker wire 16AWG 2-conductor CMP 1000ft black

Plenum-rated 16AWG speaker wire

This Monoprice 116174 cable uses 16AWG oxygen-free copper conductors inside a CMP-rated jacket approved for plenum air spaces. It is sold as a 1000ft pull of two-conductor black wire for in-wall and commercial installations. The plenum rating means the jacket resists flame spread and smoke generation in building ventilation ducts. Installers running speaker lines through drop ceilings or raised floors should select this cable type.

Verify local code and conduit needs

Before ordering, confirm that your project specification requires CMP plenum rating rather than a lower CL2 or CL3 class. Check that 16AWG gauge meets the voltage-drop limits for your longest speaker run at the planned amplifier power. Ensure the two-conductor layout matches the single-speaker drops you intend to wire; paired speaker runs need a four-conductor version instead. The 304.8 metre length suits large jobs but may exceed small residential needs.

Lifetime warranty and bare-copper conductors

Monoprice backs the cable with a lifetime warranty against defects in materials and workmanship. The 100 percent bare oxygen-free copper conductors aim to preserve signal integrity over long in-wall distances. Color-coded inner jackets inside the main CMP sheath help installers maintain polarity consistency across multiple drops. No connectors or termination tools are included in the box.
