Car audio refers to the audio system installed in the car. The reason why a system can be called a sound system is that it has the function of playing back sound. Its anti-interference technology involves filtering the interference from the power line using a choke coil in series between the power supply and the audio system to reduce external noise interference.

For the car mounted CD sound system, the most important thing to pay attention to is dust prevention. The laser head is the most expensive and vulnerable component in CDs. Although dust prevention has been considered in the design process of car audio systems, special attention needs to be paid to dust prevention due to road conditions. Careful maintenance of the audio system can effectively extend the service life of the laser head and ensure high-quality music playback for the car audio system for a long time.
