The Audi A4L underwent audio modification, which resulted in an auditory feast, but if not, it may not be as impressive as the original audio system at a large-scale facelift.
So, what kind of sound system can capture the heart of the owner of this Audi A4L. The time has come to reveal the answer, and that is the Danish Finn Listening Sound series sound system.

The Audi A4L audio upgrade plan is paired with a Fenlang RE-6.2 dual division in the front sound field, a Fenlang SQ-6.5E dual division in the rear sound field, a Fenlang RE-480 amplifier and a Fenlang AL-800.1 amplifier, and finally a Fenlang DSP8 processor, including a subwoofer.
The front soundstage is the RE-6.2 of the Fenlang High Quality Monitoring Sound series, and the mid to low frequency speakers are carbon fiber speakers. The mid to low frequency performance is stable and powerful, with fast response speed, suitable for listening to various genres. The subwoofer is installed in its original position on the door panel, while the tweeter is installed on the dashboard without damaging the original wiring.



The Fenlang SQ-6.5E, paired with a rear sound field, is a cost-effective two part set of speakers that can produce excellent sound quality whether used as a front or rear sound field. In this solution, the RE-6.2 dual frequency division in the front soundfield is paired to create a stronger surround sound in the car listening experience.


The front and rear speakers have been upgraded, and for car owners with high requirements for dynamic music, they also need to be equipped with a subwoofer. The subwoofer is installed in the trunk, which will not take up a lot of usage space.
A good speaker, of course, needs to be paired with a good amplifier. A Fenlang RE-480 amplifier and a Fenlang AL-800.1 amplifier are used to assist the front and rear sound field speakers and subwoofer, respectively. In addition, a Fenlang DSP8 is added to better utilize the speakers of the entire system, unleashing their potential without reservation.

The amplifier and processor are both installed in the trunk, which does not occupy any usage space or affect the performance of the equipment itself.

After all the equipment installation was completed, the modification technician conducted professional debugging, and the car owner got in for a trial listening. Without saying anything else, the car owner only said one sentence: "The sound quality effect of the original car audio system is much better, amazing." The car owner's high evaluation indicates that the Audi A4L's audio upgrade plan is not wrong.
Modification summary: Audi A4L audio system upgraded to the Fenlang Monitoring Sound series, providing an auditory feast that instantly changes motion. This is the strength of the Fenlang car audio system.
