4.2 Wiring Connections
- Power Connection (+12V): Connect a heavy-gauge power cable (e.g., 4-gauge) from the vehicle's positive battery terminal to the +12V terminal on the amplifier. Install an in-line fuse holder with an appropriate fuse (refer to specifications) within 18 inches of the battery.
- Ground Connection (GND): Connect a heavy-gauge ground cable of the same length as the power cable from the GND terminal on the amplifier to a clean, unpainted metal surface on the vehicle chassis. Ensure a good electrical connection.
- Remote Turn-On (REM): Connect a remote turn-on wire from your head unit's remote output to the REM terminal on the amplifier. This wire turns the amplifier on and off with your head unit.
- Audio Input (LINE INPUT): Connect RCA cables from your head unit's subwoofer or full-range RCA outputs to the LINE INPUT (L and R) on the amplifier.
- Speaker Output (SPEAKER OUTPUT): Connect your subwoofer(s) to the SPEAKER OUTPUT terminals. Ensure correct polarity (+ to + and - to -). Refer to your subwoofer's impedance rating and the amplifier's specifications for compatible loads.
4.3 Mounting
Mount the amplifier securely using the provided screws. Choose a location that is dry, well-ventilated, and away from direct sunlight or heat sources. Ensure sufficient space around the amplifier for air circulation.
5. Operating Instructions
Once installed, adjust the amplifier settings for optimal audio performance.
5.1 Control Panel Adjustments
- GAIN: This control matches the amplifier's input sensitivity to the output of your head unit. Start with the gain at minimum and slowly increase it until you hear distortion, then back off slightly. Do not use the gain control as a volume knob.
- PHASE (0°/180°): Adjust this switch to match the phase of the subwoofer with the rest of your audio system. Listen for the strongest bass response.
- SUB SONIC (10Hz-50Hz): This is a high-pass filter for subwoofers, removing extremely low frequencies that are inaudible and can cause damage to the subwoofer. Set it slightly below your subwoofer's resonant frequency.
- BASS BOOST (0dB-12dB): This control provides a boost at a specific low frequency. Use sparingly to avoid distortion and potential speaker damage.
- LOW PASS (50Hz-250Hz): This is a low-pass filter that allows only frequencies below the set point to pass to the subwoofer. Adjust it to blend smoothly with your main speakers.
5.2 Remote Bass Control
The included remote bass control unit connects to the 'REMOTE' port on the amplifier. This allows you to conveniently adjust the subwoofer output level from the driver's seat.
6. Maintenance
To ensure the longevity and performance of your amplifier:
- Periodically check all wiring connections for tightness and corrosion.
- Keep the amplifier clean and free of dust and debris. Use a soft, dry cloth for cleaning.
- Ensure that the amplifier's cooling fins are not obstructed to maintain proper heat dissipation.
7. Troubleshooting
If you experience issues with your amplifier, refer to the following common troubleshooting steps:
- No Power: Check the in-line fuse near the battery and the fuses on the amplifier. Verify all power and ground connections are secure. Ensure the remote turn-on wire is receiving +12V when the head unit is on.
- No Sound: Check RCA input connections from the head unit. Verify speaker wire connections and ensure correct polarity. Check head unit settings for subwoofer output.
- Distorted Sound: Reduce the GAIN setting. Check for proper impedance matching between the amplifier and subwoofer(s). Ensure speaker wires are not shorted.
- Amplifier Overheating: Ensure adequate ventilation around the amplifier. Check for proper impedance load on the speaker outputs.
If problems persist after following these steps, contact customer support or a qualified technician.
