6. Setup and Installation
Proper installation is crucial for the performance and longevity of your subwoofer. Please follow these steps carefully:
6.1 Choosing an Installation Location
The slim design of the SW-10 allows for versatile placement. Common locations include:
- Under the front or rear seats.
- In the car trunk.
Ensure the chosen location has adequate ventilation and is free from obstructions.
6.2 Wiring Connections
The SW-10 supports both high-level and low-level inputs. Refer to the diagram below for wiring instructions. Always disconnect the car battery before making any electrical connections.
- Power Connection:
- Connect the +12V (Red) wire from the power cable to the car battery's positive terminal. Ensure an inline fuse (25A) is installed close to the battery.
- Connect the GND (Black) wire to a clean, unpainted metal surface on the car chassis (ground point).
- Connect the REM (Blue) wire to the remote turn-on output of your car stereo/head unit. This wire turns the subwoofer on/off with your stereo.
- Audio Input Connection:
- RCA Input (Low Level): If your car stereo has RCA pre-outs, connect the Copper RCA Cable from the stereo's subwoofer/rear pre-out to the RCA INPUT on the subwoofer.
- High-Level Input: If your car stereo does not have RCA pre-outs, use the High to Low Level Input Adapter (TD-22) and the High-level Input Line. Connect the speaker wires from your car stereo to the corresponding inputs on the adapter, then connect the adapter's output to the RCA INPUT on the subwoofer. Refer to your car radio's user manual for specific wiring details.
- Remote Control Connection:
- Connect the Remote Controller cable to the 'REMOTE CONTROL' port on the subwoofer. Mount the remote controller in an easily accessible location.
7. Operating Instructions
7.1 Initial Power On
After completing all wiring, reconnect the car battery. Turn on your car stereo. The subwoofer should power on automatically if the REM wire is connected correctly.
7.2 Adjusting Settings
The subwoofer features several adjustable settings on its control panel and via the remote controller:
- PHASE (0°/180°): Adjusts the phase of the subwoofer output relative to the main speakers. Experiment with both settings to find the one that provides the most cohesive bass response.
- LOW PASS (50Hz-150Hz): Sets the upper frequency limit for the subwoofer. Adjust this to blend the subwoofer's output smoothly with your main speakers.
- BASS BOOST (0dB to +12dB): Increases the bass output at a specific frequency. Use sparingly to avoid distortion.
- INPUT GAIN (MIN/MAX): Matches the input sensitivity of the subwoofer to the output level of your car stereo. Start at MIN and slowly increase until you hear clear, undistorted bass.
- REMOTE CONTROL: The wired remote allows you to conveniently adjust the subwoofer's volume (GAIN) from your driving position.
- AUTO POWER ON (ON/OFF): If using high-level inputs, the 'AUTO POWER ON' feature can detect an audio signal and automatically turn the subwoofer on/off.
8. Maintenance
- Keep the subwoofer clean and free from dust and debris. Use a soft, dry cloth for cleaning.
- Ensure proper ventilation around the unit to prevent overheating.
- Regularly check all wiring connections for tightness and corrosion.
- If the fuse blows, replace it only with a fuse of the same type and rating (25A).
9. Troubleshooting
If you experience issues with your Ainavi SW-10 subwoofer, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No Power | Blown fuse, loose power/ground/REM wire, no power from car stereo. | Check and replace fuse. Verify all power connections. Ensure car stereo is on and sending a REM signal. |
| No Sound | Loose RCA/high-level input cables, incorrect input gain setting, car stereo settings. | Check audio input cables. Adjust input gain. Verify car stereo's subwoofer output is enabled and volume is up. |
| Distorted Sound | Input gain too high, bass boost too high, incorrect phase setting. | Reduce input gain. Lower bass boost. Adjust phase (0°/180°). |
| Subwoofer Overheats | Lack of ventilation, prolonged high volume use. | Ensure adequate airflow around the unit. Reduce volume or allow cooling time. |
10. User Tips
- For optimal sound, experiment with the subwoofer's placement in your vehicle. Small changes can significantly impact bass response.
- When adjusting the input gain, it's best to set your car stereo's volume to about 75% of its maximum, then slowly increase the subwoofer's gain until the bass sounds balanced and clear without distortion.
- Consider using sound deadening material in your car doors or trunk to minimize rattles and improve overall sound quality.
