4. Setup and Installation
This subwoofer is designed for direct installation with its built-in amplifier. Proper installation is crucial for safety and optimal sound quality. If you are unsure about any steps, it is recommended to seek professional assistance.
4.1. Choosing a Location
The ultra-thin design allows for flexible placement. Ideal locations include:
- Under the driver's seat
- Under the passenger's seat
- Behind the back seat
- In the trunk (if space allows)
Ensure the chosen location does not obstruct vehicle controls, airbags, or passenger movement. Allow for adequate ventilation around the unit.
4.2. Wiring Connections
Refer to Figure 2.6 for the control panel layout. The subwoofer requires power, ground, and an audio input signal.
- Power (12V): Connect the included red power cable to the 12V terminal on the subwoofer and run it directly to the positive (+) terminal of your car's battery. Install an appropriate fuse (not specified, but typically 20-30A) within 18 inches (45 cm) of the battery for protection.
- Ground (GND): Connect the black ground cable to the GND terminal on the subwoofer. Secure the other end to a clean, unpainted metal surface of the vehicle's chassis, ensuring a solid electrical connection.
- Remote Turn-On (REM): Connect the yellow remote turn-on wire to the REM terminal on the subwoofer. Connect the other end to the remote output of your car's head unit (stereo). This wire tells the subwoofer to turn on and off with your car's audio system.
- Audio Input (INPUT): Connect the RCA audio cables from the RCA output of your car's head unit to the INPUT (L/R) jacks on the subwoofer. If your head unit does not have RCA outputs, you may need a high-level input converter (not included) or use the high-level input if available on the subwoofer (not explicitly shown on the panel image, but common).
Warning: Incorrect wiring can cause damage to the subwoofer, your vehicle's electrical system, or personal injury. Always disconnect the car battery's negative terminal before performing any wiring.
5. Operating Instructions
Once installed, you can adjust the subwoofer's settings using the controls on the panel (refer to Figure 2.6).
- VOLUME (MIN-MAX): Adjusts the overall output level of the subwoofer. Start at MIN and gradually increase to your desired level.
- FREQ (50-200HZ): This is the low-pass filter (LPF) control. It determines the highest frequency the subwoofer will play. Set it to blend smoothly with your main car speakers. A common starting point is around 80-100Hz.
- BASS (0dB-12dB): This control adjusts the bass boost level. Use sparingly to avoid distortion.
- MODE (BASS/FULL): This switch likely controls the crossover mode.
- BASS: Activates the low-pass filter (LPF) for subwoofer operation, allowing only low frequencies to pass.
- FULL: May bypass the LPF, allowing the subwoofer to play a wider range of frequencies. For dedicated subwoofer use, the BASS mode is generally preferred.
Adjust these settings incrementally and listen to various music genres to find the optimal balance for your vehicle's acoustics and personal preference.
6. Maintenance
To ensure the longevity and performance of your Rimoody subwoofer, follow these simple maintenance guidelines:
- Cleaning: Regularly wipe the exterior of the subwoofer with a soft, dry cloth. Avoid using harsh chemicals or abrasive cleaners.
- Ventilation: Ensure that the subwoofer's vents are not blocked, allowing for proper airflow to prevent overheating.
- Connections: Periodically check all wiring connections (power, ground, remote, audio) to ensure they are secure and free from corrosion.
- Environmental Factors: Avoid exposing the subwoofer to extreme temperatures, direct sunlight for prolonged periods, or excessive moisture.
7. Troubleshooting
If you encounter issues with your subwoofer, consult the following table before seeking professional service:
| Problem | Possible Cause | Solution |
|---|---|---|

8. User Tips
- Placement Optimization: Experiment with placing the subwoofer in different locations (under seats, behind seats) to find the spot that provides the best bass response and sound integration for your specific vehicle.
- Gain Matching: When setting the volume, start with the subwoofer's volume at minimum and your head unit's volume at about 75%. Slowly increase the subwoofer's volume until it blends well with your main speakers without overpowering them or distorting.
- Crossover Adjustment: The FREQ (low-pass filter) setting is crucial. If your main speakers are small, set the FREQ higher (e.g., 100-120Hz). If they are larger, a lower setting (e.g., 60-80Hz) might be appropriate. The goal is a seamless transition between the subwoofer and your main speakers.
