5. Setup and Installation

Proper installation is crucial for optimal performance and safety. If you are unsure about any steps, consult a professional car audio installer.

5.1 Choosing a Mounting Location

The slim design of the AS-1 subwoofer allows for flexible placement. Common locations include under a seat, in the trunk, or in the cargo area of SUVs/Jeeps. Ensure the chosen location provides adequate ventilation and does not obstruct vehicle controls or passenger movement.

5.2 Wiring Connections

1. Power (+12V): Connect the main power wire from the subwoofer's +12V terminal directly to the positive terminal of your vehicle's battery. Ensure an in-line fuse (included in the kit) is installed as close to the battery as possible for protection.
2. Ground (GND): Connect the ground wire from the subwoofer's GND terminal to a clean, unpainted metal surface on the vehicle's chassis. Ensure a solid, secure connection for proper grounding.
3. Remote Turn-On (REM): Connect the remote wire from the subwoofer's REM terminal to the remote output of your head unit. This wire signals the subwoofer to turn on/off with your vehicle's audio system. If using high-level inputs and your head unit does not have a remote output, the "Auto Power On" feature can be used.
4. Audio Input:
   • Low-Level (RCA): Connect RCA cables from your head unit's pre-out outputs to the subwoofer's Low-Level Inputs.
   • High-Level: If your head unit lacks RCA outputs, use the provided high-level input harness. Connect the harness wires to your vehicle's speaker wires (e.g., rear speaker wires).
5. Remote Bass Control: Connect the remote bass control knob to the "REMOTE CONTROL" port on the subwoofer. This allows for convenient bass level adjustment from the driver's seat.

6. Operating Instructions

Once installed, adjust the subwoofer settings for optimal sound integration with your vehicle's audio system.

• Initial Power-Up: After all connections are secure, turn on your vehicle's ignition and audio system. The green "Power" LED on the subwoofer should illuminate. If the red "Protect" LED lights up, refer to the Troubleshooting section.
• Gain Adjustment: Start with the "Gain Input" knob at its minimum setting. Play a familiar piece of music with strong bass. Slowly increase the gain until the bass output blends well with your main speakers without distortion. Avoid setting the gain too high, as this can lead to clipping and damage.
• Low Pass Filter (LPF): Adjust the LPF knob to blend the subwoofer's output with your main speakers. A common starting point is around 80-100Hz. Experiment to find the best balance where bass sounds natural and not "boomy" or localized.
• Bass Boost: Use the "Bass Boost" control sparingly. Excessive bass boost can introduce distortion. Adjust it to add a subtle punch if desired, but prioritize clear, undistorted bass.
• Phase Switch: Experiment with the 0° and 180° phase settings. Choose the setting that provides the strongest and most impactful bass from your listening position. This helps ensure the subwoofer's sound waves are in sync with your main speakers.
• Remote Bass Control: Use the wired remote to conveniently adjust the bass level from your driving position without accessing the subwoofer directly.

7. Maintenance

Regular maintenance ensures the longevity and performance of your subwoofer.

• Cleaning: Use a soft, dry cloth to clean the exterior of the subwoofer. Avoid using harsh chemicals or abrasive cleaners.
• Connection Checks: Periodically inspect all wiring connections (power, ground, remote, audio inputs) to ensure they are secure and free from corrosion. Loose connections can lead to poor performance or damage.
• Ventilation: Ensure the subwoofer's heat sink and ventilation areas are not obstructed to prevent overheating.
• Fuse Replacement: If the subwoofer stops working and the power LED is off, check the fuse. Replace it only with a fuse of the same type and rating (15A-25A).
