Stinger SMRCA.5 Marine and PowerSports RCA Lead 0.5 Metre

The SMRCA.5 is a 0.5-metre marine and PowerSports RCA lead from Stinger, built for audio installations in boats, personal watercraft, ATVs, UTVs, and motorcycles where standard automotive RCA cables are unsuitable for long-term use. It features tinned OFC copper conductors, polyethylene dielectric insulation, a high-rate twisted-pair configuration, nickel-plated brass contacts, moulded connectors, and a flexible PVC outer jacket.

Product overview

The Stinger SMRCA.5 addresses the two primary failure modes of standard automotive RCA cables in marine and PowerSports environments: conductor oxidation and contact corrosion. Each OFC copper strand is individually coated with tin to prevent oxidation and corrosion from moisture, salt air, and condensation cycling. The machined brass RCA contacts are nickel-plated for superior corrosion resistance at the connection point, maintaining low-resistance signal transfer over extended periods of exposure where standard contacts would degrade.

The conductors are assembled in a high-rate twisted-pair configuration for noise rejection, reducing electromagnetic interference pickup common in the electrically demanding environments of boats and PowerSports vehicles. Polyethylene dielectric insulation provides stable electrical insulation with low signal loss across the audio frequency range. The flexible PVC outer jacket allows routing through the tight spaces typical of marine helm areas, motorcycle fairings, and PowerSports dash assemblies. The 0.5-metre length suits short interconnect runs between components mounted in close proximity within the same console or equipment compartment.

Features and benefits

Tinned OFC copper conductors:Each copper strand is individually tinned with a corrosion-resistant tin coating, preventing the oxidation that degrades signal transfer and causes cable failure in standard copper conductors exposed to marine and PowerSports environments. Tinned OFC combines the low resistance of oxygen-free copper with the corrosion resistance required for long-term reliability in wet and salt-air conditions.

Polyethylene dielectric insulation:Polyethylene dielectric surrounds each conductor, providing stable electrical insulation with low signal loss across the audio frequency range in temperature cycling and humid conditions.

High-rate twisted-pair configuration:Conductors are assembled in a high-rate twisted-pair arrangement that rejects electromagnetic interference and maintains signal clarity, reducing noise pickup in the electrically demanding environments of boats and PowerSports vehicles.

Nickel-plated brass contacts:Machined brass RCA contacts are nickel-plated for superior corrosion resistance at the connection point, maintaining low-resistance signal transfer over extended exposure to moisture and salt air where standard contacts would corrode and degrade.

Moulded connectors for connection integrity:The moulded connector construction provides a durable housing around the contact assembly that resists moisture ingress at the connector body, protecting the internal connection from the environmental conditions common in marine and PowerSports use.

Flexible PVC outer jacket:The flexible PVC jacket allows the cable to be routed through the tight and confined spaces typical of marine helm areas, motorcycle fairings, and PowerSports vehicle dash assemblies without kinking or cracking in cold conditions.

0.5-metre length for short interconnect runs:The compact 0.5-metre length suits short RCA runs between components mounted in close proximity, such as a marine head unit to an amplifier or DSP installed immediately adjacent in the same console or compartment.
