What brand is the introduction of car audio? And overview of car audio PCB diagram

Car audio refers to the audio system installed in the car. The most basic condition for the system to be called sound is that it has the function of playing back sound. Its anti-interference technology is to filter the interference of the power line with choke coils between the power supply and the audio to reduce the external noise interference.

For the car CD audio system, the most important thing to pay attention to is dustproof. The laser head is the most expensive and most vulnerable part of the CD. Although the car audio has been designed to prevent dust, it needs special attention due to road conditions. Careful maintenance of the audio can effectively extend the service life of the laser head, and can also make the car audio system guarantee high-quality music playback for a long time.
