DS18 PSFHDB4 – Powersports Fuse Holder & Power Distribution Block

Keep your powersports audio installation organized with the DS18 PSFHDB4 Fuse Holder and Power Distribution Block. Designed for battery-top mounting on 30Ah size batteries, this compact wiring accessory helps create a cleaner, more organized power and ground distribution setup for UTVs, ATVs, motorcycles and other compatible powersports applications.

The PSFHDB4 features nickel-plated contacts to help resist corrosion, a heat-resistant plastic housing, and a protective smoke-colored cover. It comes with four Mini ANL fuses—two 40A fuses and two 60A fuses—giving you multiple fuse options for a properly planned installation.

Whether you're installing an amplifier, upgrading an existing powersports sound system or cleaning up wiring around the battery, the PSFHDB4 provides a convenient central location for power distribution and fuse protection.

A practical choice for cleaner wiring, organized connections and a more professional powersports audio installation.

KEY BENEFITS

Battery-Top Mounting

The battery-top design helps keep power distribution close to the battery, creating a tidy installation and reducing the need to position a separate distribution block elsewhere in the vehicle.

Before purchasing, verify that the battery terminals, mounting space and connection layout are compatible with your application. Designed to fit 30Ah size batteries such as the PSX30L.

Organized Power and Ground Distribution

A dedicated distribution block helps organize electrical connections when adding audio equipment. It can simplify wiring layouts and make the installation easier to inspect and service.

Nickel-Plated Contacts

The nickel-plated contacts help resist corrosion and support reliable electrical connections in demanding powersports environments. Proper terminal preparation, secure connections and routine inspection remain important.

Heat-Resistant Housing

The heat-resistant plastic housing helps protect the distribution assembly, while the smoke-colored cover provides a finished appearance and an additional layer of physical protection.

Four Mini ANL Fuses Included

The PSFHDB4 includes:

• Two 40A Mini ANL fuses

• Two 60A Mini ANL fuses

Having multiple fuse ratings included provides flexibility when planning compatible circuits. Always select fuse ratings based on the equipment manufacturer's requirements and the wire's current-carrying capacity.

Designed for Powersports Audio

The PSFHDB4 is intended for applications such as UTVs, ATVs and motorcycles where space, wiring organization and reliable electrical connections matter.

TECHNICAL SPECIFICATIONS

Confirm terminal compatibility, wire sizing and fuse requirements before installation. The included fuse ratings are not a universal recommendation for every amplifier or electrical circuit.

WHY USE A DEDICATED POWER DISTRIBUTION BLOCK?

Adding amplifiers and other electrical accessories to a powersports vehicle can make the battery area crowded. A dedicated distribution block helps organize the connections and provides a more structured way to route power and ground for compatible equipment.

The PSFHDB4 is particularly useful when planning a new audio installation or cleaning up an existing one. Its battery-top mounting layout can help keep the wiring centralized rather than spread across multiple connection points.

A properly planned installation should still include suitable wire, secure terminals and correctly rated fuses. The distribution block is one part of the electrical system, not a substitute for correct circuit protection.

RECOMMENDED APPLICATIONS

The DS18 PSFHDB4 is a useful addition to:

• UTV audio system installations

• ATV electrical accessory installations

• Motorcycle audio upgrades

• Powersports amplifier installations

• Custom battery-area wiring layouts

• Audio system wiring cleanups

• Compatible auxiliary electrical setups

Important: Confirm that the battery layout, terminal arrangement and available mounting space suit your specific vehicle before ordering. Do not assume universal fitment across every UTV, ATV or motorcycle.

INSTALLATION CONSIDERATIONS

Confirm Battery Compatibility

Check the battery terminal layout and the available space before installing the distribution block. Ensure the assembly can be secured without interfering with the battery, vehicle bodywork or nearby components.

Choose the Correct Fuse Rating

The package includes two 40A and two 60A Mini ANL fuses. The correct fuse depends on the equipment, circuit design and wire rating. Do not select a fuse simply because it is included in the package.

Use Properly Sized Wiring

Choose power and ground wire appropriate for the current draw, cable length and installation conditions. Use secure terminals and protect wiring from abrasion, heat and moving components.

Secure All Connections

Loose electrical connections can create resistance, heat and intermittent equipment operation. Follow the equipment manufacturer's installation requirements and inspect the finished wiring before powering the system.

Protect the Installation

Keep the distribution block and wiring clear of moving parts and locations where they may be crushed or damaged. Do not assume the product is waterproof or submersible; protect it according to the vehicle's exposure and installation conditions.

PRO AUDIO CENTER TIP

If you're adding an amplifier to a UTV, ATV or motorcycle, plan the fuse holder and wiring before mounting the audio equipment.

The PSFHDB4 includes both 40A and 60A Mini ANL fuses, but the correct fuse is determined by the circuit and wire—not by whichever fuse is convenient. Check the amplifier's recommended fuse requirements and use wiring sized for the application.

A clean battery-area installation is easier to inspect, troubleshoot and maintain later.
