Why install a subwoofer in the car audio and video?

Compared with the listening environment of home audio, the internal environment of the car is lacking: a large amount of low-frequency noise is generated inside each car, which comes from the engine, road noise and tire noise, etc., thus covering up the bass frequency. However, the performance of low frequencies is extremely important when enjoying a variety of music. It is the mainstay of beautiful music, whether it is electronic bass in rock music, cello in jazz or other bass instruments, which is the rest of the music. The basis of existence. If these low frequencies are weak or ambiguous, then the real sound system will become monotonous, and only accurate low frequency performance can give you a compact, accurate, powerful and rich sound system.
So how can we make these noises less or less audible? There is a masking effect in psychoacoustics: when two sounds come at the same time, if one is louder and the other is lighter, then the former tends to cover up the latter, making people sound like there is only one sound. For example, if you put a blank tape in the recorder, you will hear a "sand" sound when you turn it on. When you use a music tape of the same material to sing, you basically can't feel the noise. This is not the noise disappearing, but The music signal is strong and it is covered up.
Another reason to add a subwoofer is that the mid-low frequency speaker, usually located on the door panel, has a small space based on its own cabinet (only relying on the limited space between the door panel and the iron plate), so it is below 60-80 Hz. The response will produce distortion, so the car audio system often cuts off the part below the 60-80Hz band, which is carried by the subwoofer. On the one hand, it can reduce the burden on the door speaker, on the other hand, the speaker in the system can work. In their respective rated frequency bands, they will perform their due quality.
Therefore, adding a subwoofer to the car (of course, a power amplifier with a matching power and impedance) can make the sound pressure of the sound played by the subwoofer reach a level that can cover the low frequency noise. This may be confusing for some car owners: So the more low-frequency noise vehicles do not need to install high-power amplifiers and subwoofers? This is true, if you want to hear pure music, only do it! But in reality, many car owners have the idea: "My car is so loud, there is no need to install amplifiers and subwoofers! This is equivalent to giving up the ability to enjoy good music in your own car. Opportunity.
