The audio system used in the BMW 320li is from Harman Kardon. Harman Kardon is a division of Harman International Industries, specializing in the production of home audio and car audio systems. The technical indicators of car audio systems include: 1. Output Power: Currently, the power indicated by most head units is primarily music power, ranging between 40W and 60W, and the power should not be too large. 2. Frequency Response: The frequency range audible to the human ear is between 20Hz and 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 of 90DB or above, 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.
