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

4.2 Wiring Connections

The subwoofer is a passive unit and requires an external amplifier (not included) to function. Connect the subwoofer to your car audio system as follows:

1. Audio Input: Locate the speaker terminals on the rear of the subwoofer box. These are typically marked with '+' (red) and '-' (black) for each channel. Connect the speaker output wires from your amplifier to these terminals, ensuring correct polarity. The subwoofer has an impedance of 4 Ohms.
2. LED Light Effect Power: The blue LED light effect requires a 12V power supply. Connect the included 12V cable to the "neon light input" terminal on the rear panel. Connect the other end of this cable to a switched 12V power source in your vehicle (e.g., accessory power), ensuring it is fused appropriately.

Important: Always ensure the vehicle's battery is disconnected before making any electrical connections. Double-check all wiring for correct polarity and secure connections to prevent damage to the subwoofer or amplifier.

5. Operating Instructions

Once the subwoofer is correctly installed and wired, you can begin enjoying enhanced bass in your car audio system.

• Power On: Turn on your car's ignition and car radio. The subwoofer's LED lights should illuminate if connected to a switched 12V source.
• Audio Playback: Play audio through your car radio. The subwoofer will reproduce low-frequency sounds (bass) from your audio source.
• Adjusting Bass: Adjust the bass level and crossover frequency settings on your external amplifier or car radio to achieve your desired sound balance. Start with low volume and gradually increase it.
• LED Effect: The blue LED light effect will operate whenever the 12V power source is active.
