With the improvement of people's living standards, people's requirements for materials have also increased, and the car audio modification has been blown up. With the increase in the number of car audio conversions, many people either do it themselves or go to some unprofessional stores to carry out cars. Audio conversion, this will inevitably lead to many serious consequences.
1: The sound field of the original car is not installed properly:
The listener (driver) can only hear the sound on the left and can't hear the right. There is no so-called sound field, that is, the stage feel, all the sounds are squeezed at the triangle A column on the left.
2: Professionally modified car audio:
The driver's seat is as if the singer is standing on the instrument panel for professional performance. The equipment behind the singer has a layered display, each playing its own music. The sound is layered and stereo surround sound.
3: The sound of the original car is not installed properly:
If there is no sound field, you can't talk about the layered sound quality. When the volume is loud, there will be a treble or a low-pitched sound, especially for the passengers in the back seat. The sound field and sound quality are indispensable.
4: Professionally modified car audio:
The treble shows that the violin frequency is as clean and transparent as the silk, and the middle sound is full and full. (Piano bass viola cello's touch keys are elastic and heavy). The bass reverb has a depth and does not diverge. Why does the subwoofer in the trunk ring on the instrument panel! That is the ejector of frequency. The frequency is harmonious, whether it is a whisper, or a bass, a medium sound, a loud sound, a high sound is not harsh, and the bass is not distorted. At high volume, the car speaks and the sound does not interfere with each other. That feeling is a word - good!
