[DiReed]

There are two main possibilities when car audio makes crackling noise: first, the audio system is interfered by strong signals; second, the voice coil wire inside the speaker is touching the coil or has poor contact. It is necessary to ask a repairman to check. Car audio is a radio device set up to relieve the boredom of drivers and passengers during travel. The earliest used was the car AM radio, later AM/FM radio, tape player, and developed to CD player and compatible DCC, DAT digital audio. The following is a brief introduction to car audio: 1. Introduction: The reason why an audio system can be called audio is the most basic condition - it has the function of playing back sound. In the audio system, at least the following points must be included to qualify as audio, this is true for any audio system, and car audio is no exception. Car audio mainly includes the main unit, speaker, and power amplifier. The main unit is the most important part of car audio, just like the human brain, what kind of sound to emit is controlled by the brain. Popular main units include RADIO main unit with only radio reception function, RADIO plus MP3 main unit, CD main unit, MP3 plus CD disc box, CD plus navigation main unit and CD/DVD/car MP5 main unit. 2. Sound source: The mechanism that can decode software and multimedia is called the sound source. This term seems difficult to understand, but it is actually very simple! The one that plays broadcast is called tuner, commonly known as radio; the one that plays cassette is called cassette player; as for the one that plays CD, it is called CD-Player, also known as laser disc player.
