How to Adjust the BYD Song Car Audio Equalizer?

[Sebastian]

The method to adjust the BYD Song car audio equalizer is as follows: 1. Check if the phase of the mid-high frequency speakers, left and right channels, and front and rear channels is correct; 2. Conduct a single-tone signal test to ensure each single-tone sound performs consistently; 3. Measure the power supply of the subwoofer amplifier to see if there is a significant voltage drop at medium volume; 4. Measure the impedance of the speakers from the amplifier end to ensure it is correct; 5. Turn up the volume to listen for any abnormal sounds from the speakers. The dimensions of the BYD Song are: length 4650mm, width 1860mm, height 1700mm, with a wheelbase of 2712mm.
