Operating Instructions

Audio Adjustment:

• Gain Control: Adjust the gain knob on the subwoofer to match the output level of your car stereo. Start low and gradually increase until desired volume is achieved without distortion.
• Low Pass Filter (LPF): Set the LPF between 50Hz and 150Hz to control the frequency range the subwoofer reproduces. This ensures only low-frequency sounds are sent to the subwoofer.
• Bass Boost: Use the bass boost control (0-12dB at 45Hz) to enhance the intensity of low frequencies. Adjust according to personal preference.
• Remote Volume Control: Use the wired remote knob for convenient real-time adjustment of the subwoofer's output level from the driver's seat.

LED Light Control:

The multicolored LED ambient lights are activated in sync with the car's power system. To control the light color and flashing frequency, you need to connect to the 'Lotus Lantern' application via Bluetooth on your smartphone.

• Download App: Scan the QR code in the instruction booklet to download the 'Lotus Lantern' app.
• Bluetooth Connection: Enable Bluetooth on your smartphone and connect to the subwoofer via the app.
• Adjust Lights: Within the app, you can select from seven different colors and ten dynamic lighting modes. You can also click on the color square to fine-tune the color.
• Power On/Off: The LED lights are designed to activate with the car's electrical system. If the car power system starts but the engine is off, the lights may remain on. It is recommended to start the car engine for prolonged use with lights. The lights can be turned off via the Bluetooth app.

Maintenance

To ensure the longevity and optimal performance of your Feikeer subwoofer, follow these general maintenance guidelines:

• Keep Clean: Regularly wipe the exterior of the subwoofer with a soft, dry cloth to remove dust and debris. Avoid using harsh chemicals or abrasive cleaners.
• Ensure Ventilation: The cast aluminum construction aids in heat dissipation. Ensure the subwoofer's vents are not obstructed, especially if installed in confined spaces like under a seat. Proper airflow prevents overheating.
• Check Connections: Periodically inspect all wiring connections (power, ground, audio inputs) to ensure they are secure and free from corrosion. Loose connections can affect performance and potentially cause damage.
• Avoid Extreme Conditions: Protect the subwoofer from extreme temperatures, direct sunlight for prolonged periods, and excessive moisture.

Troubleshooting

This section provides solutions to common issues you might encounter with your subwoofer.

Issue 1: Amplifier fails to power on

• Check the fuse: Damaged fuses can prevent current flow, resulting in no output. Replace if necessary.
• Verify correct grounding of the amplifier: Proper grounding prevents interference and electrical issues, ensuring the amplifier operates normally.
• Ensure the startup voltage for the amplifier is not below 5VDC: Low voltage can prevent the amplifier from functioning properly.
• Inspect RCA audio or high-frequency input connections to the amplifier: Proper connections ensure smooth signal transmission without interruptions or loose connections.
• Ensure speaker cables are securely connected: Loose or disconnected speaker cables can cause no output.

Issue 2: Protection indicator light activates after amplifier starts

• Check for speaker terminal shorts: Shorts in speaker terminals trigger amplifier protection mode to prevent damage.
• Lower volume potentiometer to engage overload mode: High volume levels may trigger overload protection; lowering the volume reduces the load.

Issue 3: Low power output

• Reset volume potentiometer: Resetting the volume potentiometer adjusts output volume.
• Verify filter potentiometer is correctly positioned: Incorrect filter settings can affect audio output quality and power.

Issue 4: Whistling noise

• Check RCA ground wire connection: Poor RCA ground connection can cause noise or whistling issues.

Issue 5: Amplifier overheating

• Verify speaker impedance is not below the amplifier's indicated impedance: Low impedance can lead to amplifier overload and overheating.
• Check amplifier installation location: Ventilation and heat dissipation conditions where the amplifier is installed can affect temperature management.
