Stinger SEASW8125 8GA 38 Metre Marine Siamese Pair Power & Ground Wire

Industry-first siamese dual power and ground wire in a single marine-grade jacket 38m on a heavy-duty wood spool. OFC hyper-twist tinned conductors, Type III BC5W2 marine PVC jacket, exceeds UL1426 marine standards.

Product Overview

The Stinger SEASW8125 is an 8GA, 38-metre (125ft) marine-grade siamese pair power and ground wire, supplied on a heavy-duty wood spool. The siamese pair design bonds the red power wire and yellow ground wire together in a single marine-grade jacket, allowing both conductors to be run simultaneously saving time and effort when wiring a vessel.

Built with OFC high-strand-count hyper-twist tinned conductors and a Type III BC5W2 marine PVC jacket rated to 105°C dry and 75°C wet, it exceeds UL1426 marine electrical standards and resists salt, fog, oil, and water.

Also suited to aluminium-bodied vehicles where chassis grounding is not available and the ground wire must be run back to the battery.

Features & Benefits

  • Industry-first siamese pair design — run power and ground simultaneously in a single jacket
  • OFC high-strand-count hyper-twist tinned conductors
  • Type III BC5W2 marine PVC jacket — exceeds UL1426 marine standards
  • Salt, fog, oil, and water resistant
  • Red/yellow marine standard colour coding (red = power, yellow = ground)
  • 38m (125ft) on heavy-duty wood spool

Frequently Asked Questions

What is the difference between the SEASW8125 and the SEASW4125?

Both are 38m marine siamese pair wire spools with the same OFC tinned construction and marine PVC jacket. The SEASW8125 is 8GA and the SEASW4125 is 4GA. Choose based on your amplifier's power requirements — 8GA suits lower-powered systems, 4GA suits higher-powered systems.

What is a siamese pair cable and why is it useful?

A siamese pair cable bonds two separate conductors — power and ground — in a single outer jacket, allowing both to be run in a single cable run. This simplifies routing and saves installation time, particularly in marine builds where long cable runs are common.

Why is the ground wire yellow rather than black?

Marine electrical standards specify yellow as the colour for DC negative (ground) conductors. This distinguishes marine-standard wiring from automotive-standard (black ground), helping prevent wiring errors in marine installations.

Is this wire suitable for aluminium boats and vehicles?

Yes. Aluminium-bodied vessels and vehicles cannot use the chassis as a ground return path, so a dedicated ground conductor must be run alongside the power wire. The siamese pair format makes this straightforward.

What is the difference between this spool and the SEA4283/SEA4287 wiring kits?

The SEA4283 and SEA4287 are complete 8GA amplifier wiring kits with a fixed cable length, fuse holder, and hardware. The SEASW8125 is a bulk spool of 38m — suited to larger builds, custom installations, or installers requiring more cable than the fixed-length kits provide.
