18 AWG Silicone Speaker Wire Kit
This RCA kit supplies ten feet of 18 AWG stranded tinned copper wire in red and black jackets for easy polarity identification. The silicone rubber insulation stays flexible from minus 60 °C up to 200 °C and is rated for 600 volts. It suits hobbyists wiring speakers, models, lamps or low-voltage appliances.
Sustained Load Behaviour
The 150-strand tinned copper cores resist corrosion and keep resistance low during continuous current flow. Silicone insulation does not stiffen or crack after repeated thermal cycles, so the wire maintains its ultra-flexible feel and low impedance over long runs. The intertwist winding further reduces signal interference under steady loads.
Compatibility Check
Verify that 18 AWG cross-section meets the current draw of your circuit and that the 2.3 mm outer diameter fits your routing channels. Ensure the 600 V rating exceeds your system voltage and that the ten-foot total length covers the required distance. Buyers needing longer single-colour runs or heavier gauge wire should look elsewhere.

Questions about this item
Does the 18 AWG silicone wire stay flexible and safe when run continuously at high temperature?
The insulation is rated for 200 °C high-temperature resistance and remains flexible down to -60 °C, so it handles continuous heat without stiffening or degrading.
What connectors or terminals do I need to terminate the 150-strand tinned copper ends?
The tinned 0.08 mm strands solder easily; you can use standard banana plugs, spade terminals or bare-wire binding posts that accept 18 AWG.
Will the 2.3 mm outside diameter fit through the cable channels on my vintage receiver?
At 2.3 mm OD the wire is slim enough for most legacy receiver channels, and the ultra-flexible silicone jacket bends tightly without kinking.
