[LaRichard]

BYD Song audio equalizer adjustment: Set the bass value to 8-9, midrange value to 2-3, and treble value to 5-6. When adjusting car audio, you can first turn off the midrange and treble of the front and rear channels, and listen to the subwoofer separately. Adjust the crossover, mechanical noise, and subwoofer ratio based on the sound. Then, reduce the volume of the rear channels and test the subwoofer again. The main components of car audio are the head unit, amplifier, and speakers. When purchasing, pay special attention to the performance of these three parts. The most direct way to judge the quality of the head unit is to look at its technical specifications. Below are the criteria for evaluating the head unit: 1. Output power: Most head units indicate music power, typically between 40W~60W. The power should not be too high. 2. Frequency response: The human ear can hear frequencies between 20Hz~20KHz, so this specification should at least cover this range, and the wider, the better. 3. Signal-to-noise ratio (SNR): This refers to the ratio of music signal to noise. High-end car audio systems usually have an SNR of 90DB or higher. The higher the value, the better. 4. Total harmonic distortion (THD): This indicator reflects the fidelity of sound reproduction. The lower the value, the higher the fidelity, and the better the audio effect.
