• +12V (Power): Connect to the positive terminal of the vehicle's battery via an inline fuse (not supplied, recommended 60A).
• REM (Remote): Connect to the remote turn-on output of your head unit.
• GND (Ground): Connect to a clean, solid metal point on the vehicle chassis. Ensure a good electrical connection.
• FUSE: The amplifier includes an internal fuse for protection. Do not attempt to replace with a higher amperage fuse.
• Speaker Outputs: Connect your speakers to the designated positive (+) and negative (-) terminals. Ensure correct polarity.

Input and Control Panel:

• INPUT (RCA): Connect your head unit's RCA pre-outs to these inputs.

5. Operating Instructions

5.1 Initial Setup and Adjustments

After all connections are made, proceed with the following adjustments:

• GAIN (Input Level): Start with the GAIN control set to minimum (MIN). Gradually increase the GAIN until you achieve a clear, undistorted sound at your desired volume level. Avoid setting the gain too high, as this can lead to distortion and potential damage to speakers or the amplifier.
• X-OVER (Crossover Switch): This switch selects the type of filter.
  • HPF (High Pass Filter): Allows frequencies above the set FREQ to pass. Useful for full-range speakers to prevent low bass distortion.
  • FULL: Bypasses the crossover, allowing all frequencies to pass.
  • LPF (Low Pass Filter): Allows frequencies below the set FREQ to pass. Useful for subwoofers.
• FREQ (Frequency Control): Adjusts the cutoff frequency for the HPF or LPF, depending on the X-OVER switch setting. This allows you to fine-tune the audio output to your speakers or subwoofer.

5.2 Power and Protection Indicators

The amplifier features LED indicators on the power/speaker terminal panel:

• PWR (Power): Illuminates when the amplifier is receiving power and operating normally.
• PRT (Protection): Illuminates when the amplifier's protection circuitry is activated due to a fault (e.g., short circuit, overheating, voltage issues). If this light comes on, turn off your audio system and investigate the cause.

6. Maintenance

To ensure the longevity and optimal performance of your amplifier, follow these maintenance guidelines:

• Cleaning: Periodically clean the amplifier's exterior with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners. Ensure ventilation fins are free from dust and debris.
• Connections: Regularly check all power, ground, remote, and speaker connections to ensure they are secure and free from corrosion. Loose connections can lead to poor performance or damage.
• Environment: Ensure the amplifier remains in a well-ventilated area, free from excessive heat or moisture.
