What brand is the Passat's audio system?

[VanIan]

The Passat's audio system is the American FENDER brand. The most basic requirement for a car audio system is the ability to reproduce sound, which mainly includes three parts: the head unit, speakers, and amplifier. The most direct way to judge the quality of an audio head unit is to look at its technical specifications. The technical indicators of car audio systems include: 1. Output power: Currently, most head units indicate music power, ranging between 40W and 60W, and the power should not be too large. 2. Frequency response: The frequency range that the human ear can hear is between 20Hz and 20KHz, so this indicator should at least reach this range, and the wider the better. 3. Signal-to-noise ratio: This refers to the ratio of music signal to noise. Generally, high-end car audio systems are above 90DB, and the higher this value, the better. 4. Harmonic distortion: This indicator reflects the fidelity of sound reproduction. The smaller the value, the higher the fidelity, and the better the audio effect.
