First, the left and right volumes are different.

If you find that the volume of the left and right channels of the audio is different, first check the balance button of the host, then check whether the left and right level control buttons of the input and output are the same, and also check the left and right channel settings of the amplifier input sensitivity. Are they the same. If not, you can switch the signal line and see the changes in the speakers on both sides. If it is, it means there is a problem with the host, otherwise there is a problem later.

2. High treble is silent

Sometimes when listening to a song, I find that a certain treble is silent. You can first check whether the dividing line is connected, and then use an electric meter to measure the sound emitted by the dividing line. The problem could be connecting the speaker wire input to the bass output.

Third, the volume is unstable

If the volume is high or low, first check whether the ground wire of the power supply is loose, and then check whether the input and output rca of the front and rear stages are normal. Finally, check whether the knob is normal. Many car owners like the sound quality with bass effect. If you want to modify the audio, pay attention to whether the modification is appropriate, because unstable voltage will also affect the sound quality of the car audio.

In fact, if the car does not automatically connect to the Bluetooth phone, you can manually reconnect, which is not very troublesome.
