Stinger SEA4247 7M Stinger PowerSports Marine 4GA Amplifier Kit
Stinger SEA4247 4GA 7 Metre Marine-Grade Amplifier Wiring Kit
A fully marine-compliant 4GA amplifier wiring kit with OFC hyper-twist tinned conductors, element-resistant MIDI fuse holder, and Type III BC5W2 marine PVC jacket 7 metres of cable for larger marine and powersports builds.
Product Overview
The Stinger SEA4247 is a 4GA, 7-metre marine amplifier wiring kit for marine and powersports audio installations. It uses the same specification as the SEA4243 OFC high-strand-count hyper-twist tinned conductors, Type III BC5W2 marine PVC jacket rated to 105°C dry and 75°C wet, siamese pair dual power and ground wire design, and element-resistant MIDI fuse holder with 175A MIDI fuse with 7 metres of cable for larger vessels or builds requiring longer cable runs.
Non-corrosive terminals are included, along with wire ferrules and full installation hardware.

Frequently Asked Questions
What is the difference between the SEA4243 and the SEA4247?
Both are 4GA marine amplifier wiring kits with identical specification — OFC tinned conductors, Type III BC5W2 jacket, siamese pair design, and 175A MIDI fuse holder. The SEA4243 is 3 metres and the SEA4247 is 7 metres. Choose based on the cable run length required for your installation.
What makes this wiring kit "marine-grade"?
Marine environments expose electrical wiring to salt water, humidity, fog, and UV. The SEA4247 uses tinned OFC conductors (corrosion resistant), a Type III BC5W2 marine PVC jacket, non-corrosive terminals, and an element-resistant MIDI fuse holder — all exceeding UL1426 marine standards.
Is the siamese pair design an advantage over standard separate cable?
Yes. The siamese pair bonds the power and ground wires into a single jacket, making routing cleaner and reducing the chance of wiring errors during installation.
What fuse rating does this kit include?
The SEA4247 includes a 175A MIDI fuse. Confirm your amplifier's recommended fuse rating before installation — replace the 175A fuse with the correct value if your amplifier requires a different rating.
Is this kit suitable for automotive (non-marine) installations?
Yes. While designed to exceed marine standards, the SEA4247 is fully suitable for automotive amplifier installations where superior corrosion resistance, longer cable runs, and higher wiring quality are required.
