Detailed process of car audio modification

Long-distance travel, drivers' greatest pleasure is listening to music, and good sound quality will bring drivers a pleasant journey. Imagine if you are driving at a high speed, there is no one else in the car, the stereo is not working well and you can't listen to music. Is it boring?

Usually, cars have their own stereos. Now the brand and sound quality of the car are not bad, so there is not much need to modify it at home. If you buy a used car with poor sound quality, or an old car that can only play tapes, but people who have higher requirements on sound quality can modify the car stereo.

So how do you modify the car's stereo? First of all, the most basic thing in car audio modification is to be familiar with its basic composition. Many people may not even know what the car audio system is, so how can they know? Here is a brief introduction to the basic composition of car audio and some common sense and modification precautions!

First, the car audio source (host)

How to correctly understand the basic knowledge of car audio modification! Most car stereos use CD, DVD, MD, MP3 and Bluetooth. As a sound source, which is what we usually call the host. As a sound source, its installation position is generally installed on the center console of a car. It is not only the core of all sound systems, but also an important part of sound systems. Among them, the sound quality of CD player is relatively pure, while the capacity of MP3 player and MD player is relatively large, so the function of DVD player is also relatively rich. In short, different hosts have their own strengths.

Second, the car power amplifier

The power amplifier is also the power amplifier, which is responsible for amplifying the previous audio signal and then driving the speaker. Generally speaking, most of the power amplifiers built in the host have low output power, and the sound quality effect cannot be compared with that of external power amplifiers. If you want better sound quality or push a more powerful speaker, it is essential to increase the power amplifier. Power amplifiers can be divided into Class A, Class AB and Class B according to the structure, and can be divided into single-channel power amplifiers, double-channel power amplifiers, three-channel power amplifiers, four-channel power amplifiers and five-channel power amplifiers according to the number of channels.

Third, the automobile DSP power amplifier

DSP power amplifier, also known as DSP digital power amplifier, uses DSP chip, and can adjust each parameter by computer. The biggest difference from traditional power amplifier is that DSP power amplifier can manage power amplifier better through computer, but traditional power amplifier can't do this. The DSP power amplifier has the functions of other power amplifiers, and can attenuate the overlapping frequencies caused by the environment in the car. The attenuated frequencies can be added and the distance between the speaker in the car and the human ear can be adjusted. DSP power amplifier mainly has the functions of delay processing, EQ adjustment, frequency division, etc., which can adjust the defect that the car can not be physically adjusted, completely improve the complex audio environment in the car, and make the sound quality distinct.

Fourth, the car horn

Profession is called trumpet, and trumpet is just a common name. As a restoration device in car audio, the restoration of sound channel is the most important part that affects and determines the performance and sound quality of car audio. Car horns can be divided into tweeters, midrange horns and woofers according to frequency response. According to the type, it can be divided into set speakers and coaxial speakers. Coaxial speaker is a full-frequency speaker, which can respond to all frequencies, and the high, medium and low tones are on the same axis. The suit horn is designed separately and equipped with a sound splitter, which can get better full-frequency response and sound field distribution design.

Five, car subwoofer

The subwoofer is the subwoofer, which is used to compensate the low frequency and reproduce the ultra-low frequency. It can be divided into active subwoofer and passive subwoofer. A perfect sound system, subwoofer is also indispensable, its function is to make the low frequency of the whole sound system have better output and the music is fuller. But one thing, the subwoofer consumes a lot of power, which may reduce the life of the battery!

Matters needing attention in refitting car stereo with intransitive verbs

1, audio equipment should be properly selected and balanced, and the price should be in line with your own budget and the music style should be determined.

2. Choose a professional refitting shop. The refitting master needs to be skilled in disassembly and assembly, and the technology is excellent, and try not to change the original car route.

3. Sound insulation measures should be taken during modification, and a quiet and comfortable listening environment is very important.

4, speakers and other audio equipment should be installed firmly, to avoid the phenomenon of loosening or falling off due to vibration in the later stage, which will affect the sound quality.

5. The rear power fuse box should be far away from the audio signal line.

6, don't arbitrarily increase the power amplifier, blindly increasing the power amplifier will not only be better, but will lead to a decline in sound quality. If an amplifier is added, heat dissipation should be considered in the installation position.

7. All positive terminals of the power supply should be protected and connected with special connectors.

8. It is very important to do effective debugging after modification.

After understanding the above knowledge, do you have a further understanding of car audio modification? When car owners modify car stereos, they mainly match them according to their own needs. Before refitting, you should consider what aspects of the sound need to be improved, and refit it according to the space of your car.

Besides choosing a brand with the right price and quality, you should also know your listening style. Finally, find a professional refit shop. The professionalism of the refitting shop and the master also determines the final refitting effect, so it is also very important. If you want to learn car stereo modification, you can go to a regular car school and learn it in a week, and the cost is not very high.
