4. Setup and Installation
The BOSS MR6B speakers are designed for boat mount applications. Proper installation is crucial for optimal performance and longevity.
4.1 Mounting Considerations
- Location: Choose a mounting location that provides adequate clearance behind the speaker for its depth (approximately 2.19 inches) and allows for proper sound dispersion.
- Surface: Ensure the mounting surface is flat, sturdy, and free from obstructions.
- Water Protection: Although these speakers are waterproof, avoid mounting them in areas where they will be constantly submerged or exposed to high-pressure water jets.
4.2 Installation Steps
- Prepare Mounting Hole: Using a template (often included or available from the manufacturer), mark and cut a circular opening for the speaker. The speaker size is 6.5 inches.
- Wiring: Connect the speaker wires from your amplifier to the terminals on the back of the speaker. Ensure correct polarity (positive to positive, negative to negative) for optimal sound. These speakers use coaxial connectivity.
- Secure Speaker: Insert the speaker into the mounting hole. Align the mounting holes on the speaker frame with the pre-drilled holes on the mounting surface. Use the provided screws to secure the speaker firmly. Do not overtighten.
- Test: Once all speakers are installed and wired, reconnect the battery and test the audio system.
