Monoprice 141402 18AWG Speaker Wire

This 500ft spool of 18AWG speaker wire uses two conductors made from oxygen-free bare copper with 99.95 percent purity. The CL2-rated PVC jacket meets in-wall fire safety codes for residential installations. Color-coded conductor jackets allow quick polarity identification during setup. Pure bare copper offers lower resistance than copper-clad aluminum alternatives.

Suited for stereo and home cinema runs

Installers pulling cable through walls or ceilings for multi-room audio or surround sound will appreciate the CL2 rating and 152.4 metre length. The 18AWG gauge handles typical speaker loads over moderate distances. Buyers needing heavier gauge for very long runs or high-current applications should look at thicker wire options.

18AWG oxygen-free copper conductors

The defining specification is the 18AWG conductor size combined with 99.95 percent pure oxygen-free bare copper. This construction keeps cable resistance low enough to preserve amplifier damping factor and speaker impedance curve integrity. CCA wire at 68 percent conductivity introduces audible losses that this design avoids.

Highlights

  • High-purity oxygen-free copper (99.95% pure) for lower resistance

  • Colour-coded PVC jackets on each conductor for quick polarity identification
  • CL2-rated outer jacket approved for in-wall installation
  • 500 ft (152.4 m) reel supplies long runs in one piece

Questions about this item

How can I verify the wire is conducting properly after installation?

Measure the loop resistance with a multimeter; for 500 ft of 18 AWG pure copper expect roughly 3.2 Ω total, well under the 5 % rule for 8 Ω speakers

What comes in the box and what must I source separately?

The reel supplies 152.4 m of CL2-rated, two-conductor 18 AWG wire with colour-coded PVC jackets; you will need banana plugs, spade lugs or bare-wire connections for your amplifier and speakers

Which gauge and length should I choose for my run?

This single SKU is 18 AWG and 500 ft; it suits runs up to about 50 ft per channel for 8 Ω loads — longer runs or 4 Ω dips need thicker wire
