The soundaktor and sound booster firmware for your car holds a configuration file that determines the specific behavior and sound of the device. This tool can be used to view and finetune these specifics to your own needs. It is specifically meant for SAK-GEN2 devices, produced by Kendrion (formerly Kuhnke).
Part numbers for this device are ... 907 159 for the internal soundaktor and ... 907 160 for the external soundaktor.

Credits to him, Alex, for doing all his research.

Flash the firmware with VCP or ODIS to your car*
Enjoy the changes.
*If you don't know how to flash firmware, please refer to the manual of your favorite tool (like VCP or ODIS).
It's not possible to "download' the firmware from your car. Firmware is shared online, and can be found on my github page.
No. This tool is very specific to GEN2 devices. Modifying GEN2.5 firmware with this data will lead to bricked hardware.
Make sure you set a default sound profile.
No. It can make you feel like it's faster, or cooler, or more tailored to your own needs. It can also make your neighbours angry, or make your car sound like shit.
I'm not kidding... this kind of "questions" I get almost daily: People who hardly take the time to write a nice message and then expect that I spend time helping them. And they keep spamming me, getting more rude by the hour, demanding I help them, sometimes even sending threats.
Compare it to ordering food at a restaurant: Will you demand food to be delivered NOW, and for free? And would you expect a quality meal, if you acted like that in a restaurant?
Don't forget: I'm a human being and I'm not some service you're paying for. Being nice doesn't cost a thing. My time and effort does.
Yes I do, see here. However, there's no public repository for this site and these tools. There were a couple of cases where I saw my own work being sold by companies or shady individuals. If you are interested in having the sourcecode because you want to sell the tools, contact me via Github. Or if you are Volkswagen A.G. and want to hire me: contact my boss.
