Wiring Connections
Follow these general steps for wiring. Always ensure the vehicle's battery is disconnected before making any electrical connections.
- Power Connection: Connect the red power cable (V+) to the car battery's positive terminal. Ensure an inline fuse (15A-25A, as specified) is installed close to the battery.
- Ground Connection: Connect the black ground wire (GND) to a clean, unpainted metal surface on the vehicle chassis. Ensure a secure connection for proper grounding.
- Remote Turn-On: Connect the blue remote wire (REM) to your car stereo's remote output. This wire signals the subwoofer to turn on/off with your stereo.
- Audio Input:
- RCA Input (Low Level): If your car stereo has RCA pre-outs, connect them to the subwoofer's RCA input ports (CH1 to red, CH2 to black).
- High-Level Input: If your car stereo does not have RCA pre-outs, use the high-level input by connecting the speaker wires from your car stereo directly to the subwoofer's high-level input terminals.

- Phase Control: Adjust the phase (0° or 180°) to ensure the subwoofer's output is in sync with your main speakers, preventing cancellation and improving bass impact.
- Low Pass Filter (LPF): Set the LPF to control the upper frequency limit of the subwoofer. A common range is 50Hz-150Hz. Adjust this to blend the subwoofer seamlessly with your main speakers.
- Bass Boost: Use the bass boost control (0 to +12dB) to increase the intensity of low frequencies. Use sparingly to avoid distortion.
- Input Gain: Adjust the input gain (Min to Max) to match the output level of your car stereo. Start with minimum gain and slowly increase until the desired volume is achieved without distortion.
- Remote Control: Utilize the wired remote control for convenient adjustment of the subwoofer's volume from your driving position.
Maintenance
To ensure the longevity and optimal performance of your subwoofer, follow these maintenance guidelines:
- Cleaning: Regularly wipe the exterior of the subwoofer with a soft, dry cloth. Avoid using harsh chemicals or abrasive cleaners.
- Connection Check: Periodically inspect all wiring connections (power, ground, remote, audio) to ensure they are secure and free from corrosion. Loose connections can lead to poor performance or damage.
- Ventilation: Ensure the subwoofer's enclosure is not obstructed, allowing for proper airflow and heat dissipation.
Troubleshooting
If you encounter issues with your subwoofer, refer to the following common problems and solutions:
- No Power:
- Check the power and ground connections for tightness and proper contact.
- Verify the inline fuse near the battery is not blown.
- Ensure the remote turn-on wire is correctly connected and receiving a signal from the stereo.
- No Sound:
- Confirm all audio input cables (RCA or high-level) are securely connected.
- Check the input gain setting on the subwoofer; it might be set too low.
- Ensure the car stereo's volume is up and not muted.
- Distorted Sound:
- Reduce the input gain on the subwoofer or the volume on your car stereo.
- Adjust the bass boost and low pass filter settings to prevent over-driving the subwoofer.
- Check for loose wiring or damaged speaker cones.
