2. Safety Information

Please read all safety instructions before installing or operating the speakers. Failure to follow these instructions may result in damage to the product, property, or personal injury.

• Power Source: Ensure the power source is disconnected before installation to prevent electrical shock.
• Wiring: Use appropriate gauge wiring for connections. Incorrect wiring can lead to overheating and potential fire hazards.
• Mounting: Securely mount speakers in a stable location to prevent detachment during vehicle operation or rough water conditions.
• Water Exposure: While water-resistant, avoid submerging the speakers. Ensure all connections are properly sealed to prevent water ingress.
• Volume Levels: Prolonged exposure to high volume levels can cause hearing damage. Operate at safe listening levels.

3. Package Contents

Verify that all items are present in the package before beginning installation:

• Two 2-way speakers with fixed grilles
• Eight M5x30mm Stainless steel machine screws
• 8 Speed clips
• Warranty information
• Specifications and template on box

4. Setup and Installation

The Pioneer TS-MR2040 speakers are designed for surface mounting and easy integration into existing marine audio systems. Follow these steps for proper installation:

1. Preparation: Disconnect power to the audio system. Choose a suitable mounting location that allows for adequate clearance behind the speaker and is structurally sound.
2. Marking and Cutting: Use the provided template (found on the box) to mark the cutout area. Carefully cut the opening, ensuring a clean edge.
3. Drilling Pilot Holes: Drill pilot holes for the mounting screws. It is recommended to start with a smaller diameter drill bit than the screw size to ensure a snug fit and secure adhesion, especially in fiberglass.
4. Wiring: Connect the speaker wires to the appropriate terminals. The TS-MR2040 features gold tinsel wire and gold-plated wire terminals for improved current transfer and corrosion resistance. Note that the positive and negative speaker connectors may differ in size; adjust existing connectors if necessary for a secure fit.
5. Mounting: Place the speaker into the cutout. Ensure the water-resistant urethane gasket is properly seated to create a seal. Secure the speaker using the eight M5x30mm stainless steel machine screws and speed clips. Do not overtighten.
6. Final Check: Once mounted, reconnect power to the audio system and test the speakers.

5. Operating Instructions

The Pioneer TS-MR2040 speakers are designed to deliver clear and powerful audio. For optimal performance, ensure your audio source and amplifier are compatible and properly configured.

• Power Handling: These speakers have a maximum power handling of 200 Watts and a nominal power handling of 40 Watts. For best results and to prevent distortion, especially at higher volumes, it is recommended to use an amplifier that matches or slightly exceeds the nominal power rating.
• Sound Quality: The dual-cone design, Reflex Horn tweeter technology, and IMPP composite cone woofers work together to produce rich bass, clear highs, and a wide frequency response.
• Audio Source: Use high-quality audio sources (e.g., streaming services, FLAC files) to fully appreciate the sound capabilities of these speakers. Lower quality sources may not do justice to the speaker's performance.

6. Maintenance

The Pioneer TS-MR2040 speakers are built with durable, weather-resistant materials to withstand harsh marine conditions. Regular maintenance will help preserve their appearance and performance.

• Cleaning: Gently wipe the speaker grilles and cones with a soft, damp cloth to remove salt residue, dirt, or dust. Avoid using harsh chemicals or abrasive cleaners.
• UV Protection: The AES (Acrylonitrile-Elastomer Styrene) glass fiber reinforced basket and magnet cover, along with the pure white AES grilles, are designed to resist fading and yellowing from direct sunlight and heat.
• Water Resistance: The water-resistant IMPP (Injection Molded Polypropylene) composite cones and elastomer surrounds resist the effects of saltwater and humidity. Ensure the mounting area remains sealed to prevent water damage to internal components.
• Inspection: Periodically inspect the speaker surrounds for any signs of cracking or deterioration. The elastomer surround is designed to resist color fading and running, extending product longevity.

7. Troubleshooting

If you experience issues with your Pioneer TS-MR2040 speakers, refer to the following common problems and solutions:

• No Sound:
  • Check all wiring connections at both the speaker and the audio source/amplifier. Ensure they are secure and correctly polarized (+ to +, - to -).
  • Verify that the audio source (head unit, amplifier) is powered on and functioning correctly.
  • Confirm that the volume is turned up and not muted.
• Distorted Sound:
  • Reduce the volume level. Distortion often occurs when the amplifier or speakers are overdriven.
  • Check for loose connections or damaged speaker wires.
  • Ensure the speakers are receiving adequate power. For optimal performance, especially at higher volumes, an external amplifier is highly recommended.
  • Inspect the speaker cones and surrounds for any physical damage.
• Intermittent Sound:
  • Check for loose or corroded wiring connections.
  • Ensure the audio source is stable and not experiencing interruptions.
