Speaker Wire 12AWG 1000ft CL2

This 12AWG speaker wire uses two conductors of oxygen-free bare copper rated above 99.95 percent purity. The 1000ft spool suits whole-home audio runs and custom installer lengths. Black CL2-rated PVC jacketing meets in-wall fire codes for residential and light-commercial projects.

Upgrade from CCA speaker wire

Copper-clad aluminum wire is only about 68 percent as conductive as pure bare copper, adding resistance that shifts the load away from the speaker impedance curve. Switching to this pure copper construction removes that extra resistance when runs approach the five-percent threshold of the lowest speaker impedance. The improvement is most audible on longer cable paths or with speakers that dip below nominal impedance.

In-wall audio cable for amplifier

Color-coded PVC on each conductor simplifies polarity identification during termination. The CL2 rating allows routing through walls and ceilings without conduit in typical residential builds. Installers pull the required length from the 304.8-metre spool and terminate with banana plugs, spades or bare wire as the system demands.

Questions about this item

What conduit size or wall cavity depth is required for this 12AWG CL2 cable?

The cable has a black CL2-rated PVC outer jacket suitable for in-wall runs; allow space for the full 1000ft length and the 12AWG conductor diameter when planning conduit fill.

How do you identify polarity when terminating the two conductors?

Each of the two oxygen-free bare copper conductors is individually jacketed in colour-coded PVC, so match the marked jacket to the positive and negative terminals on your speakers and amplifier.

When should this 12AWG pure copper wire be replaced or re-terminated?

Inspect connections periodically for oxidation or loose strands; re-terminate if the 99.95% pure copper ends discolour or the PVC jacket shows cracking from heat or UV exposure.
