Monoprice 144332 Speaker Wire 12AWG 250ft White

SKU CH-V8XB-Z64XV

CL3-rated 12AWG pure bare copper speaker wire on a 250ft spool for in-wall audio runs

  • TypeOthers
  • ColorWhite
  • CL3 rating supports safe in-wall installation
  • 12AWG pure bare copper conductors exceed 99.95% purity for low resistance
  • 250ft spool provides ample length for multi-room runs
  • Two colour-coded PVC jackets simplify polarity identification
  • Pure copper avoids CCA's 68% conductivity penalty for cleaner sound

12 AWG CL3 In-Wall Speaker Cable

This 250 foot reel of 12 AWG speaker wire is built for whole home audio installations. It uses pure bare copper conductors with a purity greater than 99.95 percent. The CL3 rating meets fire safety codes for in-wall and ceiling runs. White PVC jackets on each conductor simplify polarity identification during installation.

Suitable for long runs and in-wall installs

Installers running wire through studs or joists will appreciate the code compliant CL3 jacket and low resistance 12 AWG gauge. The pure copper design avoids the higher resistance of copper clad aluminum alternatives. Buyers needing pre terminated cables or banana plugs should look at other options. This product supplies raw wire on a spool only.

250 foot continuous length on a single reel

The decisive specification is the 250 foot continuous length supplied on one reel. It determines how many zones or rooms you can wire without splicing. Verify the total distance required for your project before purchasing. The 12 AWG gauge supports the low resistance needed for extended runs.

Questions about this item

What diameter conduit or raceway is required for the 12 AWG CL3 rated cable?

The 12 AWG conductors fit standard residential conduit sizes; CL3 rating permits in-wall runs without additional conduit where local code allows.

How do I identify polarity when terminating the two conductors?

Each conductor has colour-coded PVC jackets — typically one clear and one marked — so you can maintain consistent polarity at speaker and amplifier ends.

Will the bare copper oxidize and require re-termination over time?

Pure bare copper above 99.95 % purity resists oxidation far better than CCA; terminations normally stay reliable for the life of the installation.
