The right Sound Booster for you

How much does a Sound Booster cost?

How respectively where get the Sound Booster installed?

The sound generator is installed at the underbody of the car. If there isn't enough space, it can be installed inside the spare wheel recess. The Modules are assembled in the inside and get connected.

What size is the sound generator?

The spheric sound generator has a perimeter about 64 cm, a diameter of around 20 cm and a height of ca. 16 cm.

Will the sound generator get installed into the exhaust?

No, the Sound Booster is not integrated into the exhaust. This makes the Active Sound System easy to remove again.

Am I able to install the Sound Booster by myself or do I need to visit a specialist workshop?

This depends on the kit you want to install. The vehicle specific kit can be installed by you. The universal kit needs to be welded, so it might be secure to let it be installed by a specialist workshop.

The Sound Booster is not working after installation. Where is the error? Defect module?

There are some little errors which can happen on pinning after the installation of the Active Sound System. With the help of the LED status display you can solve some problems by yourself.

Have a look at our helping site with frequently error sources and how you can solve them:

I retrofitted the universal kit on my Audi and do not have any sound now. Why?

If you installed the system on a Audi A8 4H, A6 4G, A7 4G you have to encode this:
Address 09 Byte 11: Set Bit 6 to 1.

After successful encoding the Sound Boost while motor starting in dynamic mode is activated or can be activated in the individual mode, if the settings for Motor/Gear and motor sound are set to dynamic.

The retrofit kit by Audi for the A4/A5 is not getting louder with the KUFATEC module. Why?

The retrofit kit by Audi for the A4 8K and A5 8T has a setting, which keep the volume at a certain level.

We can cancel the reduction. Get the following update (complete update) in our shop and send in the control unit to us.

How can I control the system? (Via App, Cruise Control lever etc.?)

Do I have to encode my vehicle after installation?

No, you do not need to encode anything.

Is there a TÜV (Technical Supervisory Association) assessment for the registration?

No, but we know several customers, which got an entry via individual acceptance.

Are there any problems at my next TÜV (Technical Supervisory Association) date, when the system is installed?

The use of a Sound Booster is not permitted without an entry in the vehicle documents in the area of the Road Traffic Licensing Regulation (German StVZO). The noise emission of the vehicle is increased after retrofitting the system. The regulations of the StVZO must be observed. It is therefore recommended to ask for a specific entry option at the relevant TÜV (Technical Supervisory Association) / DEKRA (another German technical inspection agency) office before retrofitting. Outside of Germany, please observe the applicable laws for vehicle registration in your country.

  • Windows 8.1

FAQ - Sound Booster - Software

Do I have the software on my computer?

No, you have to download the software and install it. Sign up on this page and then you can download the software.

Do I need to purchase the program? If yes, what’s the price?

No, the software is completely free and everyone with a KUFATEC Sound Booster can download the APP.

Where do I get the software to change the sound profiles?

You can download the software on this page. You have to register or log in and download the software.

Which operating systems are supported?

  • Windows XP SP3
  • Windows Vista
  • Windows 7
  • Windows 8
  • Windows 8.1
  • Windows 10 

The system is now usable on MAC as well!

How do I connect the software to my car?

With a mini USB cable and a computer.

Can I hear changes instantly?

Yes. If you change one or more points you can click on “test” and accelerate using the virtual gas pedal with ignition on or with the gas pedal of your car.

Which settings can I do with the software / APP?

You can change all available profiles with the software.

Current functions are:

  • Profiles activate / deactivate
  • Power-Start-settings
  • Settings for non round at idle
  • Illustration of the tone characteristics of the module via speed and volume diagram

On the one hand you can set the volume in the respective speed section (0–100%), on the other hand you can additional map the real speed to a virtual speed.

Which advantages do I have in contrast to already existing system on the market? (APP, Cruise Control lever, etc.)

You can make very detailed settings and save up to 6 sound profiles. Therefore you can generate a special tone for every speed. For example you create a “motorway profile” in which the volume is set down at a speed of 130 km/h. Other apps only allow an increase or decrease in volume for the whole sound.

Additional you can download certain profiles for and from others on this website.

Can I set additional tone profiles or will the existing be deleted?

You can save up to 6 profiles. You can edit the profiles as much you want and can reset them to factory settings to get the standard sounds back.

Can I use the software also on my already built-in ex works sound system (Audi)?

As soon you have installed our KUFATEC Module, you can use the software on that too.

Does the software works with older models (software and car model)?

The software works for every car model which have a KUFATEC Sound Booster Module with the hardware 29/15. At the same time a minimum software status of 2.15 is required. If this isn’t the case, you can update the system via the USB port.

If you have an older hardware level as 29/15, you can purchase and download a hardware update in our shop.

Why don't I necessarily need the software for the Maserati module?

With the Maserati module the software to change the profile is not absolutely necessary, because the volume is completely controllable via the cruise control. Of course, you can still download the software and customize profiles there.

Where do I get notifications about new updates?

You’ll find new updates on this website (Download area) or with a click on the update button in the software.

Is there an advice for a good sound profile?

A good sound profile is, of course, subjective. In principle the profile has to be adjusted with the volume and the possible speed translation to the respective vehicle.

Find some examples in the download section.

Can I deactivate the Sound Booster at a certain speed? For example on the motorway?

Yes, you can individually adjust the system to your speed.

Can I also download ready-made profiles?

Yes, you can download ready-made profiles on this website in the download section.

Can I accidentally ruin my sound with wrong settings?

No, you can always reset the settings to the factory ones. Even unsuccessful updates can’t delete or damage the software.

On which devices can I use the APP?

The software is best usable at laptops and desktop computers. We support Windows and Mac.

Can I use the software with the smartphone?

No. There also isn’t a special Android or Apple-App. The detailed handling of the software would get lost at smartphones.

Reasons, why we don't support an APP at a glance:

  • if the mobile phone connected via wi-fi, the internet is not available at the phone, because it expects a wi-fi router. That means you can't receive push-notifications and can't use the internet as well
  • if the mobible phone is connected with bluetooth, the hands-free module is not usable
  • legal terms do not allow the interaction of the mobile phone during driving
  • adjustments of the diagrams is just not representable with an APP in this range of functions
  • depending on the vehicle you have various possibilities to change the profiles:
    Control opportunities

For example: If you want to increase the tone about 20 % while standing, other apps can just increase the whole sound. We provide the opportunity, to adjust an own sound characteristic and volume at each speed. With this option, you can decrease the the volume of the Sound Booster individually for motorway journeys.

To change profiles fast is connected with higher expenditure. It’s a lot easier to use the button or the remote control for that. In addition the use of smartphones while driving is a high risk and should be avoided.
