Audio system wiring

This 18AWG two-conductor speaker wire supplies 100 continuous feet of oxygen-free 99.95 percent pure bare copper on a spool. The clear PVC jacket carries a blue stripe for quick polarity identification. It is rated CL2 for in-wall installation. Pure copper avoids the added resistance of copper-clad aluminium alternatives.

Conductor gauge and material

The 18AWG pure bare copper conductors keep total loop resistance low so the amplifier sees the speaker’s true impedance curve. Oxygen-free copper at 99.95 percent purity maintains conductivity over long runs. This gauge balances flexibility with minimal signal loss for typical home audio distances.

Installation context

The 30.48 metre spool lets you cut exact lengths for each channel without buying multiple short cables. CL2 rating allows routing inside walls or ceilings where local codes require it. Builders who need a heavier gauge for very long runs or lower-impedance loads should look elsewhere.

Questions about this item

How does the 18AWG gauge perform in a real home audio run?

At 18AWG the resistance is higher than the 0.803 ohms per 100 feet measured for 16AWG pure copper, so keep runs short or use lower-impedance speakers to stay within the 5 percent rule.

What does the CL2 rating allow for installation?

CL2 means the jacket meets fire-safety requirements for in-wall and ceiling runs in residential buildings, so you can route it inside walls without conduit.

What does the spool need to fit through during a pull?

The wire is on a spool with a flexible PVC jacket about 18AWG overall diameter, so it passes through standard 1/2-inch or larger drill holes and raceways.
