A tidy, weather-ready way to power and connect your amp on boats, UTVs/ATVs, motorcycles, and adventure builds
Clean wiring is the backbone of great sound—especially in powersports where vibration, moisture, and tight mounting spaces are part of the deal. The MB Quart PS-AMPKIT is a universal 8-gauge amplifier wiring kit that includes the power, ground, speaker, RCA, and remote turn-on leads you need for a straightforward, reliable install. Purpose-selected cable lengths make routing easy in side-by-sides, motorcycles, and small watercraft, while the included in-line fuse holder, terminals, and cable ties help you finish the job neatly and safely. It’s a smart addition to any automotive accessories build where durability and tidy wiring matter as much as the amp itself.
Key Features
- Complete 8-Gauge Kit for Powersports Installs – Includes power, ground, speaker wire, RCA interconnect, remote turn-on, and in-line fuse holder.
- Right-Sized Lengths for Small Vehicles – 17 ft power/ground/RCA and 12 ft speaker run simplify routing in UTVs/ATVs, bikes, and compact boats.
- Corrosion-Resistant Connectivity – Nickel-plated RCA and quality hardware help maintain a clean signal path in harsh environments.
- Universal & Installer-Friendly – Works with most mono or 2-channel amplifiers; labeled wiring and included ties streamline a clean, professional finish.

Why it’s a great choice for powersports
From frame-rattling trails to salty air, powersports wiring takes a beating. This kit’s 8-gauge power and ground reduce voltage drop on longer runs, helping your amp perform consistently. The nickel-plated RCA resists corrosion, and the included fuse holder puts critical protection close to the battery. Pre-measured lengths are long enough for most side-by-sides and small boats without stuffing extra loops under panels. The result: a clean, reliable signal and power path that lets your amplifier (and speakers) shine.
Install tips
- Mount the fuse near the battery: Place the in-line fuse holder within 12–18" of the power source. Insert the fuse after all connections are made.
- Ground like a pro: Keep the ground lead short. Sand to bare metal and secure with a star washer for bite.
- Separate signal and power: Route the RCA and remote on the side opposite the power cable to minimize noise.
- Protect every pass-through: Use grommets and loom where wire passes through metal or areas exposed to splash or vibration.
- Plan for the future: If you may add another amp or zones, consider running extra RCAs now while panels are open.
Terms to Know
- 8-Gauge (8-ga): The thickness of the power/ground wire. Lower numbers = thicker wire, which helps reduce voltage drop and heat on longer runs.
- RCA Cable: The shielded stereo cable that sends low-level audio from your source (radio) to the amplifier.
- Remote Turn-On (Blue Wire): A small 12V signal that tells the amplifier to turn on/off with the head unit, so you don’t need a separate switch.
- In-Line Fuse Holder: Houses a protective fuse on the power cable; it protects the vehicle and wiring in case of a short.
- Ground (GND): The return path for electrical current. A short, solid ground point is critical for stable performance and low noise.
- Speaker Wire (12-ga): Connects the amplifier’s outputs to your speakers or subwoofer; heavier gauge helps on longer runs or higher power.
If you want a clean, dependable amplifier install in a UTV, ATV, motorcycle, or small boat, the MB Quart PS-AMPKIT gives you everything essential in one box—proper 8-ga power/ground, corrosion-resistant RCA, remote lead, speaker wire, and a fuse holder—plus the hardware to finish it right. It’s the easy, trusted way to wire up your system for great sound and long-term reliability.
