Compare each part of the car audio system to a certain organ of the body, and explain the role of each part of the audio modification for us through visual metaphors and descriptions. He compares its decisive host CD to the human brain, highlighting the important role of the host in the entire sound system; and compares the speaker to a human voice, he analyzed that choosing different speakers will produce different sounds, just like Everyone's sound quality is different; and the power amplifier is like a human lung, and the level of sound depends on "the size of the lung capacity"; he compares these lines to blood vessels, and compares power lines to arterial blood vessels. Since the audio modification often increases the power of the original car audio, in order to achieve the effect of voltage regulation, the selection of the quality of the line equipment and the arrangement of the lines play a great role in the sound effect. Moreover, the audio circuit equipment has strong technical requirements in the process of audio modification. A little carelessness can easily lead to a short circuit and a fire.

Audio modification is a very complicated project, not as simple as changing the head as everyone thinks. It mainly includes three steps:

The first is the selection of equipment: in the process of selecting equipment, the car owner chooses the music form he likes according to the owner's habits and hobbies. There are three kinds of music choices for car audio, one is HI-FI - American rock music, its sound effect is more powerful, with a metallic texture, and young people change more; the second is pop music that pays more attention to the original sound effect , with German style; there is also light music, also known as "voice music", which is famous for its beauty and gorgeousness.

The second step is the installation of the equipment. During the installation of the equipment, we must pay attention to the position, angle and matching of the equipment with the space. In order to achieve the perfect embodiment of car audio, it is necessary to comprehensively consider factors such as the model of the car, the size of the car space, the height of the owner, and the choice of audio brand. In addition, in the process of audio modification, we must pay attention to the problem of line direction, so as to avoid hidden safety hazards.

The third step is the audio debugging process. The non-professional audio modification shop is very lacking in this aspect. Therefore, the audio debugging technology has become the key to distinguish the professional from the non-professional. Manager Zhou said that the audio debugging technology plays a key role in the success of "Bizhou Audio". In the process of debugging the audio, the technician must integrate the three factors of the car's own characteristics, the owner's requirements and the audio equipment, and strive to perfectly reflect the sound of the treble, mid-range and bass frequency bands to achieve a perfect and comfortable hearing experience. , to pursue the depth, breadth and breadth of music.
