The owner of the CAR to enter this BMW new 4 series time is not very long, in the process of using the car, the owner found that the quality of the car's audio system is general, the music played out is very dull, the sense of layering is also very chaotic, can not show the texture of the music, in order to improve the quality of the audio, the owner decided to do audio upgrades for the car.
BMW's new 4 Series sound upgrade
Since there was no previous modification experience, and it was a new car, the owner did not want to make too many changes to the car's audio system. Therefore, this audio modification is based on the upgrade scheme of the Steg BMW special suit.

Comparing the dismantled original car horn with the horn used for the upgrade, it can be clearly seen that the horn of the original car is rough and the material is simple, while the sound field horn used for the upgrade is exquisitely made and the material is sufficient, just a simple comparison, and the quality is immediately revealed.

As a special soundstage horn for BMW cars, the Steg BMW special suit is simple and convenient to install, and it is just right to install it directly in the car in situ. Although the original car does not have a tweeter, the triangle position at the door panel seems to be reserved for the tweeter, and the original position installed in the car is just right, which can also be truly non-destructive modification. Not only that, it also inherits the deep technical accumulation of Steg, which makes the music it plays full of sound and layered.

The resolution of the original car host is average, resulting in poor audio signal quality, so the technician added a high-power multi-channel DSP for the car, which can filter the noise generated by the host work, make the audio signal more clean and complete, and also act as a power amplifier to make the horn play more outstanding.
Add a High Power Multiplex DSP to the car
【Modification effect review】The car audio system after the upgrade is completed, from the appearance point of view, there is no trace of any change, but listening to the music effect, you can find that the music it plays is very transparent, the details are also in place, and the texture of the music has been improved by more than one grade.
