For many car enthusiasts, the sound system is an indispensable part of the car, and many car owners, in order to obtain better sound quality, will make car sound system modifications to advance. With more and more people having this demand, the profession of car audio modification has been further developing in recent years. When it comes to car audio modification and promotion, the orientation of accessories is very important and should be paid attention to. Therefore, today LED Bluetooth audio will introduce to us the requirements for car audio modification and promotion, which accessories should be paid attention to in terms of orientation.

1. Sheet metal

Along the way to the promotion of car audio modification, sheet metal can be said to be the top element that needs attention. Generally speaking, during the driving process of a car, when the sheet metal and the audio system replay at low frequencies, if the sheet metal is too thin, resonance will occur and low-frequency noise will be emitted, which will cover up the low-frequency part of the music more, thereby affecting the three-dimensional effect of the car audio system.

2. Horn

In addition to differences in body structure, the installation habits of the original horn in different cars are also different. If you only purchase a regular stereo sound system, car owners will place the rear door speaker of their car at the rear door. If an AV system is installed, in order to seek surround effect, Japanese and American cars can be imitated, and speakers can be added to the rear headrest. As for the front door horn of a car, the mid range horn should be installed at the front door panel, and the high range horn should have sound effects when installed on the dashboard or A-pillar.
