Upgrading your boat’s sound system can transform your time on the water, whether you’re fishing, cruising, or throwing a dockside party. JL Audio is known for its high-quality marine-grade audio equipment, making it a top choice for boat owners who want powerful, clear sound. In this guide, we’ll walk you through the steps to install a JL Audio stereo system on your sportfish boat.

Why Choose JL Audio for Your Boat?

JL Audio is renowned for its marine audio systems built to withstand harsh marine environments without compromising sound quality. Their equipment is saltwater-resistant, UV-protected, and designed to deliver superior sound, even against engine noise and wind.

What You’ll Need For a Full Install:

• JL Audio Marine Head Unit (e.g., JL Audio MediaMaster®)

• JL Audio Marine Amplifier

• JL Audio Marine Speakers

• Wiring Kit (marine-grade power and speaker wires)

• Fuse Holder and Fuse

• Marine-Grade Connectors and Heat Shrink Tubing

• Wire Strippers and Crimpers

• Drill and Hole Saw (for speaker and head unit installation)

• Marine Sealant

Step 1: Plan Your Installation

Before diving in, decide where to mount the head unit, amplifier, and speakers. Choose locations that are:

• Dry and Ventilated: To prevent damage and overheating.

• Accessible: For easy wiring and control access.

• Acoustically Optimal: Aim for even sound distribution around the deck and cockpit.

Step 2: Mounting the Head Unit

1. Choose a Location: The dashboard or helm is ideal for visibility and easy control access.

2. Cut the Mounting Hole: Use the template provided with the head unit. Drill a pilot hole and follow with a hole saw or jigsaw.

3. Seal the Edges: Apply marine sealant around the cutout to protect against water intrusion.

4. Install the Head Unit: Secure it using the included mounting hardware.

Step 3: Installing the Speakers

1. Select Speaker Locations: Choose areas that are unobstructed and provide the best sound projection.

2. Cut Speaker Holes: Use the provided template. Ensure a snug fit.

3. Wire the Speakers:

• Run marine-grade speaker wire from the head unit to each speaker location.

• Use heat shrink tubing and marine connectors for corrosion resistance.

4. Mount the Speakers: Secure them with stainless steel screws and apply sealant around the edges.

Step 4: Installing the Amplifier

1. Choose a Location: Keep it in a dry, ventilated area, away from direct sunlight and salt spray.

2. Mount the Amplifier: Use vibration-resistant mounts for stability.

3. Power Wiring:

• Connect the power wire from the boat’s battery to the amplifier using a fuse holder close to the battery for protection.

• Ground the amplifier to a its own negative ground cable directly to the battery 

4. Connect the RCA and Speaker Cables: Route them away from power cables to avoid interference.

Step 5: Powering Up and Testing

1. Double-Check All Connections: Make sure all wires are secure and insulated.

2. Power On the System: Turn on the head unit and check all speakers for sound output.

3. Adjust Settings: Fine-tune the equalizer settings for optimal sound quality.

Step 6: Final Touches

• Secure and Organize Wires: Use zip ties and cable clamps for a clean installation.

• Waterproofing: Double-check all seals and connections for water resistance.

Tips for a Professional Finish:

• Use marine-grade wiring to prevent corrosion. JL Audio brand wire suggested. 

• Apply dielectric grease on all connectors for added protection.

• Always disconnect the battery before starting the installation to avoid short circuits.
