The reason for no sound from the rear audio system in the BMW X1 is a loose audio plug. Introduction to the audio system: The car audio system is a radio and playback device installed to alleviate the boredom of drivers and passengers during travel. The earliest version used was the car AM radio, later followed by AM/FM radios, tape players, and evolved to CD players and digital audio systems compatible with DCC and DAT. Nowadays, car audio systems have reached high standards in sound quality, operation, and vibration resistance, capable of withstanding the bumps of cars on rough roads while ensuring stable performance and perfect sound quality. How the audio system works: It amplifies various sound signals played by the audio source to drive the speakers to produce sound. From a technical perspective, the amplifier acts like a current modulator, converting alternating current into direct current, which is then controlled by the sound signals played by the audio source to transmit currents of varying magnitudes at different frequencies to the speakers. This allows the speakers to produce sounds of corresponding magnitudes and frequencies. Audio refers to all sounds other than human speech and music, including sounds from the natural environment, animal sounds, sounds from machines and tools, and various sounds produced by human actions.
