Stinger SEASW4125 38m Marine 4GA Power & Ground Wire

Stinger SEASW4125 Marine Grade 4 Gauge Siamese Pair Power and Ground Wire 38 Metre Roll with BC5W2 Compliant Tinned OFC Conductors

The SEASW4125 from Stinger is a marine grade 4 gauge siamese pair power and ground wire supplied on a 38 metre (125ft) heavy-duty wood spool. Built to BC5W2 marine standards with tinned OFC conductors, it keeps power and ground wire paired in a single jacket for simplified routing in marine installations and aluminium-bodied vehicle applications requiring battery grounding.

Product overview

Running separate power and ground cables through a vessel doubles the routing work and increases installation time. The SEASW4125 addresses this with a siamese pair configuration that pairs both conductors in a single marine-grade jacket, allowing power and ground to be run together in a single pass. The 38 metre spool provides sufficient cable for larger vessel installations or multiple amplifier runs without the need for additional cable purchases.

The BC5W2 marine PVC jacket is rated to 105°C dry and 75°C wet with resistance to salt, fog, oil, and water, exceeding UL1426 marine wiring standards. The red power and yellow ground colour coding follows marine wiring conventions for clear identification. The SEASW4125 is also well suited to aluminium-bodied vehicles where running a dedicated ground wire back to the battery is required rather than grounding to the chassis.

Features and benefits

Siamese pair power and ground configuration: An industry-first paired design that keeps both the power and ground conductors in a single marine-grade jacket, allowing both wires to be routed together in a single pass and reducing installation time in marine and aluminium-bodied vehicle applications.

BC5W2 marine-grade PVC jacket: The highest marine-grade jacket classification, rated to 105°C dry and 75°C wet, with resistance to salt, fog, oil, and water. Exceeds UL1426 marine wiring standards for reliable performance in harsh marine environments.

Tinned high strand count OFC conductors: Tinned conductors prevent oxidation and corrosion in wet and salt-exposed environments, while the high strand count OFC construction maximises current transfer and flexibility during installation.

38 metre heavy-duty wood spool: Supplied on a 38 metre (125ft) heavy-duty wood spool, providing sufficient cable for larger vessel installations or multiple amplifier runs from a single purchase.

Marine standard colour coding: Red power and yellow ground conductors follow marine wiring colour conventions for clear identification throughout the installation.

Suited to aluminium-bodied vehicles: The siamese pair configuration is also a practical solution for aluminium-bodied vehicles where a dedicated ground return to the battery is required rather than a chassis ground.

Frequently asked questions

What is the advantage of a siamese pair power and ground wire?
The siamese pair configuration keeps both the power and ground conductors in a single jacket, allowing both to be routed together through the vessel in a single pass. This reduces installation time and simplifies cable management compared to running two separate cables.

Is the SEASW4125 suitable for freshwater and saltwater marine environments?
Yes. The BC5W2 rated jacket and tinned OFC conductors are designed to resist moisture, salt, fog, oil, and water exposure, making the SEASW4125 suitable for both freshwater and saltwater marine audio installations.

Can the SEASW4125 be used in aluminium-bodied vehicles?
Yes. The siamese pair configuration is well suited to aluminium-bodied vehicles where chassis grounding is not practical and a dedicated ground return to the battery is required. Both the power and ground cable can be run together in a single pass back to the battery.

How much cable does the 38 metre spool provide?
The SEASW4125 spool provides 38 metres (125 feet) of siamese pair cable, giving sufficient length for larger vessel installations or multiple amplifier cable runs from a single spool purchase.

How does the SEASW4125 differ from the Stinger SEA marine wiring kits?
The SEA range wiring kits (such as the SEA4243 and SEA4247) are pre-cut installation kits supplied in fixed lengths with a fuse holder and installation hardware included. The SEASW4125 is a bulk cable spool for installers who need a longer run or want to cut cable to a custom length for their specific application.
