Setup and Installation
Mounting the Amplifier
Choose a mounting location that is dry, well-ventilated, and secure. Avoid mounting the amplifier directly on carpet or in enclosed spaces that restrict airflow. Use the provided mounting screws to secure the amplifier firmly to a solid surface in your vehicle.
Wiring Connections
Ensure all connections are tight and secure to prevent electrical shorts or poor performance.

- Power Connection (+12V): Connect a direct wire from the vehicle's positive battery terminal to the +12V terminal on the amplifier. Use an appropriate gauge power wire (e.g., 8-gauge or 4-gauge depending on total system power) and install an in-line fuse holder within 18 inches of the battery.
- Ground Connection (GND): Connect a wire of the same gauge as the power wire from the GND terminal on the amplifier to a clean, unpainted metal surface on the vehicle's chassis. Ensure a good electrical connection.
- Remote Turn-On (REM): Connect a thin wire (e.g., 18-gauge) from the REM terminal on the amplifier to the remote turn-on output of your head unit. This wire turns the amplifier on and off with your car stereo.
- Speaker Output: Connect your subwoofer(s) to the SPEAKER OUTPUT terminals. Ensure correct polarity (+ to + and - to -). This amplifier is designed for monoblock operation, typically driving a single subwoofer or multiple subwoofers wired to a compatible impedance (e.g., 2 ohms).

- RCA Input (INPUT R/L): Connect RCA cables from your head unit's subwoofer or full-range pre-outs to the INPUT R and L jacks on the amplifier.
- Remote Bass Knob: Connect the remote bass level control knob to the 'REMOTE' port on the amplifier using the provided cable. Mount the knob in an accessible location for easy adjustment.
Operating Instructions
Initial Power-Up
After all connections are made, reconnect the vehicle's negative battery terminal. Turn on your car stereo. The 'PWR' indicator on the amplifier should illuminate, indicating it is receiving power and operating correctly. If the 'PRT' (Protection) indicator illuminates, refer to the Troubleshooting section.
Adjusting Controls
- GAIN: This control matches the amplifier's input sensitivity to the output level of your head unit. Start with the GAIN set to minimum (0.1V) and slowly increase it until you hear distortion, then back off slightly. Do not use the GAIN control as a volume knob.
- BASS BOOST: This control provides an adjustable bass enhancement at a specific frequency. Use sparingly to avoid distortion or damage to your speakers.
- LPF (Low Pass Filter): This filter allows only frequencies below the set point to pass through to the subwoofer. Adjust the LPF (40Hz - 180Hz) to blend the subwoofer's output seamlessly with your main speakers. A common starting point is around 80Hz.
- REMOTE (Bass Knob): The remote bass knob provides convenient control over the subwoofer's output level from the driver's seat.
Maintenance
- 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 cooling fins are not obstructed to maintain proper heat dissipation.
- Do not use harsh chemicals or solvents for cleaning.
Troubleshooting
If you experience issues with your amplifier, refer to the following common problems and solutions:
- No Power (PWR indicator off):
- Check the in-line fuse near the battery and the fuses on the amplifier. Replace if blown.
- Verify +12V power, ground, and remote turn-on connections.
- Protection Mode (PRT indicator on):
- This indicates a fault condition (e.g., short circuit, overheating, low voltage).
- Check speaker wiring for shorts.
- Ensure proper ventilation around the amplifier.
- Verify vehicle battery voltage.
- No Sound:
- Check RCA input connections from the head unit.
- Verify speaker connections and polarity.
- Ensure head unit volume is up and source is selected correctly.
- Distorted Sound:
- Adjust the GAIN control to prevent clipping.
- Check speaker impedance compatibility.
- Reduce BASS BOOST if it's causing distortion.
