JFONG 18AWG 2-core speaker wire 150 ft CCA 26 strand IP68 12/24V

Application and audience

This 18 AWG two‑conductor speaker wire suits installers running low‑voltage LED strip lighting, lamps or bulbs at 12 V or 24 V. The 150 ft spool provides 45.72 m of red and black conductors for positive and negative runs in homes, vehicles, schools or auditoriums. Copper‑clad aluminium cores with a PVC jacket keep the cable lightweight at .5 kg per spool.

Thermals noise and power handling

Rated for continuous operation from ‑40 °C to 80 °C, the wire meets IP68 waterproofing and V‑1 flame‑retardant standards. The 300 V insulation margin far exceeds the 12/24 V target voltage, so normal LED loads generate negligible heat and no audible noise. The 26‑strand construction remains flexible during routing without compromising the protective jacket.

Sustained load behaviour

Under extended 12 V or 24 V lighting loads the CCA conductors maintain stable resistance, and the anti‑oxidation coating resists corrosion over long runs. The IP68 rating ensures moisture ingress does not degrade performance, while the V‑1 jacket retains integrity at the upper temperature limit. Installers can rely on consistent voltage delivery across the full 150 ft length without thermal softening.
