This manual provides essential information for proper installation, operation, and maintenance to ensure optimal performance and longevity of your speakers.
2. What's in the Box
Your Diamond Audio MSPRO65 package includes the following components:
- MSPRO65 6.5-inch Motorsport Midrange Speakers (2 units)
Note: Additional mounting hardware or wiring may be required and sold separately, depending on your specific installation.
3. Installation Guide
Proper installation is crucial for the performance and durability of your MSPRO65 speakers. These speakers feature a robust design and weather-resistant components, making them suitable for outdoor applications.
3.1 Mounting Considerations
- Location: Choose a mounting location that provides adequate space for the speaker's dimensions (6.5 inches diameter, 2.62 inches depth) and allows for clear sound projection.
- Surface Preparation: Ensure the mounting surface is clean, flat, and free from obstructions.
- Drilling: If drilling new holes, use appropriate tools and ensure precise measurements to avoid damage to the speaker or vehicle.
- Weather Protection: While the speakers are waterproof, ensure wiring connections are properly sealed and protected from direct water exposure to prevent corrosion.
3.2 Wiring Connections
Connect the speaker wires to your amplifier or head unit. Pay close attention to polarity (positive to positive, negative to negative) to ensure correct phase and optimal sound quality. Incorrect wiring can lead to poor audio performance.

4. Operating Instructions
Once installed, your MSPRO65 speakers are ready for operation. These speakers are designed for high-output sound with minimal power draw, providing crystal-clear highs and an immersive listening experience.
- Power On: Turn on your audio system (head unit/amplifier).
- Volume Control: Start with the volume at a low level and gradually increase it to your desired listening level. Avoid excessive volume that causes distortion, as this can damage the speakers.
- Audio Settings: Adjust your amplifier's gain, crossover settings, and equalization (EQ) to optimize sound quality for your specific vehicle and listening preferences. Refer to your amplifier's manual for detailed instructions.
- Break-in Period: Allow a short break-in period (typically 10-20 hours of normal use) for the speaker components to loosen up and achieve their full sound potential.
5. Maintenance
The MSPRO65 speakers are built with superior durability and weather-resistant components. Regular maintenance will help preserve their performance and appearance.
- Cleaning: Use a soft, damp cloth to wipe down the speaker grilles and cones. Avoid harsh chemicals or abrasive cleaners.
- Inspection: Periodically inspect the speaker surrounds and cones for any signs of damage or wear. Check wiring connections for corrosion or looseness.
- Protection: While waterproof, prolonged exposure to extreme conditions (e.g., direct high-pressure water jets) should be avoided.
