2. Adjust Sliders: Move a slider up to boost that frequency band or down to cut it.
3. Bass Frequencies (Low End): Adjust the lower frequency sliders (e.g., 30Hz-120Hz) to control the depth and impact of bass.
4. Mid-Range Frequencies: Adjust the middle frequency sliders (e.g., 250Hz-2kHz) to control vocals and instruments.
5. Treble Frequencies (High End): Adjust the higher frequency sliders (e.g., 4kHz-16kHz) to control the brightness and clarity of high notes.
6. Listen and Refine: Make small adjustments and listen carefully to the changes. Aim for a balanced sound that suits your preferences and vehicle acoustics.
