Wiring Connections

Ensure all power, ground, remote, and speaker wires are connected securely and correctly. Use high-quality, appropriately gauged wiring.

• Power (B+): Connect to the positive terminal of the vehicle's battery via a fused power cable. The fuse should be located within 18 inches of the battery.
• Ground (GND): Connect to a clean, unpainted metal surface of the vehicle chassis. Ensure a solid, low-resistance connection.
• Remote (REM): Connect to the remote turn-on output of your head unit or a switched 12V source.
• Speaker Outputs: Connect your speakers to the designated output terminals. Observe correct polarity (+/-).
• Input Signal: Connect your audio source (head unit) to the amplifier's input. The MX800.4 supports both 2-channel and 4-channel input modes.

Adjusting Settings

• Input Mode: Select between 2CH (2-channel) or 4CH (4-channel) input based on your head unit's output configuration.
• Frequency (FREQ): Adjust the crossover settings for each channel (Front/Rear). Options typically include:
  • HPF (High Pass Filter): Allows frequencies above the set point to pass. Useful for full-range speakers.
  • LPF (Low Pass Filter): Allows frequencies below the set point to pass. Useful for subwoofers (though this is a full-range amp, LPF can be used for mid-bass).
  • FULL: Allows all frequencies to pass through.
• Sensitivity (SENS): Adjust the input sensitivity to match the output voltage of your head unit. Start with the sensitivity at minimum and slowly increase until desired volume is achieved without distortion.
• Status Indicators: The amplifier features status LEDs (PWR/PRT) to indicate power status and protection mode.

Maintenance

The MX800.4 amplifier is designed for durability. Regular maintenance is minimal but important for long-term performance.

• Keep the amplifier clean and free of dust and debris. Use a soft, dry cloth for cleaning.
• Periodically check all wiring connections to ensure they are secure and free from corrosion.
• Ensure adequate airflow around the amplifier to prevent overheating.
• Do not use harsh chemicals or abrasive cleaners on the amplifier.
