Car audio mainly includes three parts: main unit, speaker and power amplifier. The mainframe is the most important part of the car's audio, just like the human brain, what kind of sound to make, is controlled by the brain. Currently popular hosts include CD host, MP3 plus CD disc box and CD/DVD/car MP5 console. MP5 console has replaced the general car CD audio system, and the massive hard disk capacity has replaced the traditional disc. Car MP5 has become the mainstream today.
