What brand is the audio system in the new Focus?

[JacksonLee]

The audio system in the new Focus is from the Pioneer brand. Here is the relevant information: 1. Output power: Most current head units indicate music power, ranging between 40W~60W, and the power should not be too high. 2. Frequency response: The human ear can hear frequencies between 20Hz~20KHz, so this specification 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, with high-end car audio systems typically 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 thus the better the audio effect.
