Car stereo or TV?

Audio amplifier is a single special effect designed and made separately. The playing effect of TV is mainly video, supplemented by power amplifier. The design is simple as long as it can output sound, so the effect is different.

The sound gain of acoustics restores the real scene, and the TV effect is just an ordinary simulation scene. Speakers have obvious high, medium and low levels, while TV speakers only have midrange units. The main reason is that the high and low tones are simulated effects.
