RCA 18 AWG Silicone Speaker Wire

This RCA Small Spool wire provides two 13.2 ft lengths of 18 AWG stranded tinned copper conductor in black and red silicone insulation. It suits DIY audio wiring, speaker connections and low-voltage projects needing flexible, high-purity oxygen-free copper.

600 V rating and temperature limits

The wire carries a nominal voltage rating of 600 V and a test voltage of 2000 V. Its silicone rubber jacket remains flexible from -60 °C to +200 °C, so it handles extreme cold and heat without stiffening or degrading.

7.5 A current capacity with 150-strand flexibility

Each conductor uses 150 strands of 0.08 mm tinned copper for a 1.19 mm core and 2.3 mm overall diameter, rated at 7.5 A. The fine stranding and soft silicone allow tight bends and easy stripping, but the 18 AWG cross-section limits runs to shorter distances or lower-power loads.

Questions about this item

Which spool length should I choose for a typical stereo run?

Each colour ships on a 13.2 ft spool, giving you 13.2 ft of black and 13.2 ft of red wire for left and right channels.

What does the 18 AWG rating mean once the wire is installed in a speaker system?

The 18 AWG stranded tinned copper conductors (150 strands of 0.08 mm) present very low resistance, so signal loss stays minimal across the 13.2 ft runs.

What does the 600 V insulation rating cap in practice?

The silicone rubber jacket is rated for 600 V and tested to 2000 V, so it safely handles the voltages found in ordinary audio installations.
