4. Operating the Subwoofer
Once installed, the subwoofer operates in conjunction with your car audio system and amplifier. Adjustments for bass output and crossover frequencies are typically made on the amplifier or head unit.

- Play a familiar piece of music with strong bass content.
- Slowly increase the amplifier's gain until the desired bass level is achieved without distortion.
- Adjust the low-pass filter (LPF) on your amplifier or head unit to blend the subwoofer's output seamlessly with your main speakers. A common starting point is around 80-100 Hz.
- Adjust phase settings if available, to ensure the subwoofer's output is in phase with the main speakers.
