In most cases – yes. The Thunder generator is designed as a universal replacement for factory sound generators installed in many Audi, BMW, and Porsche models. However, for 100% certainty of compatibility with your specific vehicle, please contact us and provide the VIN code or the exact model and year of manufacture.
No, the generator itself is just a speaker. To generate sound, it needs an external control unit (ECU) that analyzes data from the CAN bus. If you already have a Thunder system (a kit with an ECU), then this generator is suitable for expansion. If you want to replace a broken factory generator in a car where it came from the factory, then this generator will work with your car's factory control unit.
The warranty on the generator is 2 years. The stated service life is up to 10 years.
Yes, it is possible. In some cases, you may need to fabricate brackets and attach them by welding to the generator housing.
The Thunder generator reproduces the same sounds that the control unit (factory or Thunder) generates. The sound quality is very high, many users note that Thunder sounds cleaner and bassier than the originals, but subjective perception may vary.
Technically – yes, but you will also need to purchase a Thunder electronic control unit (ECU) and a wiring kit, which are sold separately or as part of kits. The generator itself will not work without a "brain".
Possibly. Many modern cars have similar active sound systems installed. If you are confident that your car has such a generator and you need a replacement, this option may work. For accurate compatibility diagnosis, it is better to consult with us.
The Thunder generator is specifically designed for automotive applications. It is resistant to vibrations, temperature changes, and humidity, ensuring its durability. Cheap alternatives may fail quickly or produce distorted sound. Thunder delivers reference sound quality and reliability.
No, replacing the speaker is a passive operation. It does not affect the electronic control units or the vehicle's software. You simply connect a new device instead of the old one.
The package includes only the sound generator itself. Wiring and mounting hardware are typically used from your vehicle's factory setup. If you are using the generator to expand a Thunder system, the necessary wiring kit is already included in the basic set, or needs to be purchased separately.

Was looking for a replacement for a BMW (they have the same speakers). This one fit perfectly! Now my car also sounds like a sports sedan. Build quality is excellent, wires are soldered reliably. I recommend it to everyone!
Aleksejs
The product is high quality, completely solved the problem with a failed generator on the Audi. The sound is now even better than the original. But delivery times let me down – they promised 15 days, but it arrived after 25. Otherwise, everything is super.
Dzintars
I have a kit with one generator, decided to add a second. Bought this one – and now I have a real V8! The sound became voluminous. The generator came in perfect packaging, everything intact. Thank you!
Armands
Bought it for a BMW X7 just in case, but installed it right away. There is a difference from the factory one – the sound is denser and bassier. You can see that the speaker is high quality, the magnet is big. Very satisfied with the purchase!
Ilmars
Installed it instead of the factory unit in an Audi Q5. The connectors matched perfectly, the sound became even more interesting than before. No vibrations, holds firmly. Very satisfied with the price-quality ratio. Will recommend!
Raimonds
Wanted to experiment with sound. Took one generator, connected it to my control unit – works like clockwork. Clear sound, no distortion. Now thinking of buying a second one for volume. Quality is super!
Normunds
Bought it as a replacement for a Mercedes GLC. The factory speaker failed after winter. This one fit without problems, the sound is clean, bass is deep. Very glad I didn't have to overpay for the original. Thank you!
Arturs
Gave it to a friend for New Year, he has a BMW X6, the factory speaker started "wheezing". Fit perfectly, now he has emotions from the sound again. The packaging quality is excellent, the generator itself looks very reliable.
Guntis
On a Porsche Panamera, an error appeared for the sound generator. The mechanic recommended this as a replacement. The errors are gone, the sound is back. Quality is top notch, vibration-resistant mounting. An excellent alternative to the original.
Valdis
Bought it to expand my kit. Added a second generator to my system – the effect is amazing! Volume appeared. The generator itself is heavy, solid, you can see it's made conscientiously. I recommend buying.
Juris
Was looking for a part for an Audi A8. Original would take a month to wait and cost cosmic money. Thunder saved me! The generator arrived quickly, installed in half an hour. Works perfectly, sound like a new car. Thank you very much!
Edgars
Replacing the factory speaker in a BMW X5 Series went smoothly. All connectors fit, the sound is even better than before. Now there is no rattling at high RPM, clean bass. Very satisfied with the purchase.
Richards
Decided to build my own configuration for a project. Took a pair of these generators. Quality is just excellent, powerful magnets, good speaker cone excursion. The sound is very rich. I recommend it for DIYers!
Aivars
A friend's Audi had a sound generator burn out. I recommended this one to him. It was a bolt-on fit, the sound is identical to the original, but the price is much nicer. Happy as an elephant! Thanks for a quality product.
Kristaps
The generator is excellent! Fit into the BMW like it was made for it, the sound is clean, no complaints. But delivery could have been organized faster – I waited almost 4 weeks. Minus one point for that. The product itself is fire!
Andris
Bought it as a spare, as the car is not new, you never know. But I decided to install it right away for an experiment on a Mercedes. Sound appeared where there was none before. The body quality is excellent, contacts are reliable. Thank you!

I was looking for a replacement for a Porsche Cayenne for a long time. The original costs crazy money. The Thunder guys offered their generator – it fit like a native! The sound is top notch, now my beast roars again. Thank you!
Martins
On my BMW X5 the factory "sound actuator" stopped working. Replaced it with Thunder – and everything worked like clockwork! Quality is even better than the original, the sound is cleaner. Installation took 20 minutes. Excellent product!
Janis
Decided to upgrade my system from one generator to two. Bought this one – and now I have a full stereo exhaust! The sound has become much more voluminous. The generator is fully compatible with the factory mounting. I recommend it!
