What brand is the Passat's audio system?

[McJune]

The Passat's audio system is from the American brand FENDER. The most basic requirement for a car audio system is the ability to reproduce sound, which mainly includes three components: the head unit, speakers, and amplifier. The most direct way to evaluate the quality of an audio head unit is by examining its technical specifications. The key technical indicators of a car audio system are: 1. Output Power: Currently, most head units indicate music power, ranging between 40W and 60W, and the power should not be too high. 2. Frequency Response: The human ear can hear frequencies ranging from 20Hz to 20KHz, so this indicator should at least cover 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 have a ratio above 90DB, and the higher this value, the better. 4. Harmonic Distortion: This indicator reflects the fidelity of sound reproduction. The lower the value, the higher the fidelity, and the better the audio effect.
