RCA BOAT-WIRE 18 AWG 50ft Marine Cable

This 50-foot duplex cable uses 18 AWG tinned copper conductors with a PVC jacket built to UL 1426 and SAE ABYC standards. The tinning resists oxidation and salt-water corrosion while the insulation withstands gasoline, battery acid, abrasion and temperatures up to 150 °C dry or 75 °C wet. It is rated for 600 volts and suits boat, automotive, solar and outdoor installations.

Suits installers needing corrosion-resistant

Buyers who want pre-terminated speaker cables with connectors should look elsewhere. The two bare conductors require stripping and termination, so it is not a plug-and-play solution. Projects demanding a third conductor for combined power and signal runs will need a different cable construction.

18 AWG tinned copper duplex construction

The 18 AWG gauge and two-conductor layout determine current capacity and voltage drop over the 50-foot length. Verify that this gauge meets the ampacity and distance requirements of your specific circuit before purchase.

Questions about this item

Will the 18 AWG tinned copper conductors work reliably with my older marine stereo that uses standard copper speaker terminals?

Yes, the tinned copper strands are designed for marine environments and connect to standard speaker terminals without any adapter, providing corrosion resistance that plain copper lacks.

How can I verify the wire is performing correctly once I have run it through the bilge and connected the speakers?

Measure continuity across each 50 ft conductor with a multimeter; you should see a low resistance reading consistent with 18 AWG copper, and the speakers should play cleanly at normal volume without distortion.

Does the 50 ft spool include any connectors, heat-shrink or crimp terminals, or do I need to buy those separately?

The package contains only the 2-conductor tinned copper cable with PVC insulation; you will need to purchase ring terminals, spade connectors or heat-shrink tubing separately for termination.
