The original paper cone speaker has a small voice coil with only 20 watts of power.

Fox's original car was equipped with six speakers. Needless to say, the workmanship is rough and the sound quality is average. The voice is unclear, the treble is not accurate, and the bass is not heavy. It can only be used for daily radio listening.

Analysis of modification scheme: Cossini K4 Bluetooth player can be selected as the sound source for DSP processing. A set of German Conch 3. 16s signature version is installed in the front sound field, and a set of Rockpower R600 coaxial speakers is installed in the rear sound field. Rockpower R485 four-way power amplifier is used for the sound insulation part, and high-energy super shield sound insulation material is used for the four doors.
