About Car modification:

Conventional 12V battery cars for cars and motorcycles can be directly modified for power supply; 24V battery cars such as large trucks are not recommended, because the voltage will exceed 24V after the car is started. Unless the voltage is reduced by other equipment, the power amplifier will heat up too much and will be used for a long time. It is not good for the chip and even burns out.
