5. Setup and Installation
Proper installation is crucial for the amplifier's performance and longevity. Ensure the vehicle's battery is disconnected before starting installation.
5.1 Mounting Location
Choose a mounting location that provides sufficient ventilation for heat dissipation. Avoid mounting in direct sunlight or in enclosed spaces without airflow. Secure the amplifier firmly to a solid surface using the provided screws.
5.2 Wiring Connections
Refer to the diagram below for correct wiring. Use appropriate gauge wiring for all connections.

- Power Input (+12V): Connect to the positive terminal of the vehicle's 12V battery. It is recommended to use 4 gauge (or above) power lines.
- Ground (GND): Connect to a clean, unpainted metal surface of the vehicle chassis. Ensure a good electrical connection.
- Remote (REMOTE): Connect to the remote turn-on output of your head unit. This wire turns the amplifier on and off with your stereo. If the original car without control line, please connect to the ACC line.
- Speaker Outputs (FRONT/REAR): Connect your speakers to the corresponding terminals. Ensure correct polarity (+ to + and - to -). This is a 4-channel amplifier, supporting front and rear speaker pairs.
- RCA Inputs (IN): Connect the RCA cables from your head unit's pre-amp outputs to the amplifier's RCA inputs.

6. Operating Instructions
Once installed, adjust the amplifier settings for optimal sound performance.

- Gain Control (Gain Min/Max): Adjusts the input sensitivity of the amplifier to match the output level of your head unit. Start with the gain at minimum and slowly increase until the desired volume is achieved without distortion.
- Bass Boost (0dB/6dB/12dB): Increases the bass output at a specific frequency. Use sparingly to avoid distortion.
- Crossover Settings (HPF/LPF/FULL):
- HPF (High Pass Filter): Allows frequencies above the set point to pass through. Useful for full-range speakers to prevent them from playing low bass.
- LPF (Low Pass Filter): Allows frequencies below the set point to pass through. Essential for subwoofers to only play bass frequencies.
- FULL: Allows all frequencies to pass through, bypassing the crossover filter.
- SQ Sound Enhancement: The amplifier is designed to concentrate energy in ideal working frequency ranges for optimal speaker performance. Adjusting gain and crossover settings will help fine-tune this.
- Low Frequency Impact: The amplifier provides ample power to deliver full, dynamic low-frequency sound. Ensure your speakers or subwoofers are capable of reproducing these frequencies.
7. Maintenance
To ensure the longevity and optimal performance of your amplifier, follow these maintenance guidelines:
- Cleaning: Periodically wipe the amplifier's exterior with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
- Ventilation: Ensure that the amplifier's cooling fins are free from dust and debris to maintain proper heat dissipation.
- Connections: Regularly check all power, ground, remote, and speaker connections to ensure they are secure and free from corrosion.
- Fuse Replacement: If the fuse blows, replace it only with a fuse of the exact same type and rating. A blown fuse often indicates an underlying issue that should be investigated.
