Marine-Grade Speaker Wire for Boats and RVs

This 16 AWG tinned copper duplex cable delivers 150 feet of corrosion-resistant wiring built for saltwater and high-amperage marine systems. It meets UL1426 and SAE J378 standards for installation in bilge areas, engine rooms and shore-power circuits up to 600V.

150-Foot Length Handles Long Runs.

Each conductor uses 26 strands of 0.254 mm tinned copper, providing flexibility for routing through tight conduit and bulkheads. The 16 AWG gauge suits navigation lights, LED strips and solar arrays, but runs out of headroom for heavy thrusters or inverter feeds that demand thicker conductors.

Flat PVC Jacket Survives 6,000V Spark

Dual-layer 0.76 mm insulation exceeds 0.68 mm and 0.61 mm minimums, creating a crush-resistant 4.9 mm × 8.05 mm profile rated to 221 °F dry and 167 °F wet. Buyers needing plenum-rated jackets, armoured conduit fill or multi-conductor counts beyond two wires must specify a different cable type.

Questions about this item

Will the 16 AWG tinned copper strands handle the same 600 V rating as my existing marine panel?

Yes, the cable is rated for 600 V systems from 5 V navigation lights up to 240 V shore power, so it matches the panel voltage rating.

How can I verify the dual-layer insulation meets the 6,000 V spark and 2,000 V HIPOT tests after installation?

The jacket is built to UL1426 and SAE J378 standards with 0.76 mm inner and outer PVC layers that exceed the 0.68 mm and 0.61 mm minimums, passing those factory tests.

Does the 150 ft spool include pre-tinned ends and lugs, or must I buy connectors separately?

The spool supplies 150 ft of flat duplex cable with pre-tinned conductor ends; lugs or terminals are not included and must be purchased separately.
