1. Introduction
This manual provides essential information for the proper installation, operation, and maintenance of your LTC AUDIO BD-SWR5004 Waterproof Portable Speakers. These 2-way marine speakers are designed for use in environments where exposure to moisture is common, such as boats, cars, or other damp locations, thanks to their completely waterproof design and molded ABS casing.
Please read this manual thoroughly before using the product to ensure safe and optimal performance.
2. Safety Information
- Water Resistance: While these speakers are designed to be waterproof, they are not intended for prolonged submersion. Ensure proper installation to maintain their water resistance.
- Power Source: Connect the speakers only to an appropriate audio amplifier or head unit with compatible power output. Exceeding the maximum power rating (160 Watts peak) can damage the speakers.
- Wiring: Ensure all wiring connections are secure and correctly polarized (+ to + and - to -). Loose connections can lead to poor sound quality or damage.
- Installation: Install speakers in a stable location where they will not obstruct vision or movement. Ensure mounting surfaces are strong enough to support the speakers.
- Cleaning: Disconnect power before cleaning. Use a soft, damp cloth. Avoid abrasive cleaners or solvents.
- Temperature: Avoid exposing speakers to extreme temperatures or direct sunlight for extended periods, which can degrade materials.

- Mounting Points: Integrated into the speaker frame for secure installation.
- Wiring Terminals: Located at the rear of the speaker for connecting to an audio source.
4. Setup and Installation
4.1. Mounting Location
These speakers are designed for ceiling mount or flush installation in panels. Choose a location that provides adequate space behind the mounting surface for the speaker's depth (approximately 16 cm) and wiring. Ensure the surface is sturdy enough to support the speaker's weight (300 grams per speaker).
- Mark the desired mounting position.
- Cut a circular opening in the mounting surface according to the speaker's diameter (5 inches / 12 cm). Refer to the speaker's physical dimensions for precise cutout size.

4.2. Wiring Connections
Before making any connections, ensure your audio amplifier or head unit is turned off and disconnected from its power source.
- Identify the positive (+) and negative (-) terminals on the back of each speaker. These are typically marked.
- Connect the positive (+) speaker wire from your amplifier to the positive (+) terminal on the speaker.
- Connect the negative (-) speaker wire from your amplifier to the negative (-) terminal on the speaker.
- Ensure all connections are tight and secure to prevent signal loss or short circuits. For marine applications, consider using marine-grade wiring and connectors for enhanced durability and corrosion resistance.

4.3. Securing the Speakers
- Once wired, carefully insert the speaker into the cutout.
- Use appropriate screws (not included) to secure the speaker through its mounting points to the mounting surface. Do not overtighten.
- Attach the protective grille by aligning it with the speaker unit and pressing it firmly into place until it clicks or sits securely.
5. Operating Instructions
The LTC AUDIO BD-SWR5004 speakers function as passive audio components and do not have independent controls. Their operation is entirely dependent on the audio source and amplifier they are connected to.
- Power On: Once properly installed and wired, turn on your audio amplifier or head unit.
- Audio Source: Select your desired audio source (e.g., radio, media player, Bluetooth device).
- Volume Control: Adjust the volume using the controls on your amplifier or head unit. Start with a low volume and gradually increase it to a comfortable listening level.
- Sound Quality: For optimal sound quality, ensure your amplifier's settings (bass, treble, balance, fader) are adjusted to your preference. Avoid excessively high volumes that cause distortion, as this can damage the speakers.
6. Maintenance
Regular maintenance will help prolong the life and performance of your speakers.
- Cleaning: Periodically wipe the speaker grilles and frames with a soft, damp cloth. For marine environments, rinse with fresh water after exposure to saltwater to prevent salt buildup and corrosion. Do not use harsh chemicals, solvents, or abrasive cleaners.
- Inspection: Regularly check the mounting screws to ensure they remain tight. Inspect wiring connections for any signs of corrosion or fraying, especially in damp environments. Re-secure or replace as necessary.
- Environmental Protection: While waterproof, protecting the speakers from direct, prolonged exposure to extreme weather conditions (e.g., intense UV, freezing temperatures) when not in use can further extend their lifespan.
