How to Adjust Car Audio Sound Effects?

Steps and Methods for Car Audio Sound Effect Adjustment: 1. Preparation: Reset all additional functions of the car head unit to factory settings. Set the treble, midrange, and bass to the middle position, and ensure the left-right balance is also centered. Set the amplifier's volume (GAIN) to the minimum position (MIN), set the FILTER (filter setting) to OFF, and set the CROSSOVER to the lowest position. Apply the same settings to the subwoofer amplifier. 2. First Head Unit Adjustment: Turn on the head unit and play high-fidelity vocal tracks or tracks with strong bass dynamics. Adjust the volume to halfway or 3/5 of the maximum. 3. Front Sound Field Adjustment: First, increase the GAIN of CHANNEL-1/2 until the sound reaches the maximum acceptable volume. Then, reduce the head unit's volume and play a vocal track or a track with strong bass. Gradually increase the head unit's volume until it is slightly louder than normal listening levels. 4. Second Head Unit Adjustment: Resonance can affect sound clarity, so adjustments are needed to eliminate resonance. 5. Rear Sound Field Adjustment: Set the rear sound field to HP mode and adjust the CROSSOVER (cutoff frequency) to around 150Hz. Increase the head unit's volume to a slightly higher than normal level, then adjust the GAIN of the amplifier driving the rear sound field until you can "feel" the sound from the rear field in the front seats. 6. Bass Adjustment: Set the subwoofer amplifier's FILTER (filter setting) to LP (low-pass) position, adjust the CROSSOVER (cutoff frequency) to the lowest setting, and set the GAIN to half or 3/4 of the front sound field's level.
