Two generators create a true stereo soundstage effect. This produces a more spacious, deeper, and richer sound that you can feel with every cell of your body. This is especially relevant for larger vehicles (crossovers, SUVs, business-class sedans). Two generators provide the maximum presence effect of a powerful engine.
The kit includes instructions for connecting the electrical part of the system. We recommend having the sound generators themselves installed at a professional service center, as a lift and special tools will most likely be required.
Yes, you can. The main thing to consider is that the two generators will need to be placed somewhere under the car, closer to the rear.
Yes, the number of generators does not affect the set of available timbres. The electronic control units contain the same sound generation algorithms. Two generators simply reproduce these sounds in stereo mode, making them more realistic, richer, and more powerful. A kit with two generators on a large car will be more appropriate than if it were a single generator.
No, the total power consumption of the system remains minimal. It is still powered by the 12V network and does not create a noticeable load on the vehicle's electrical equipment, even with two speakers. Furthermore, the system is only active when the engine is running, when the power generated by the alternator is more than sufficient.
No, the sound imitation of a powerful petrol car will be the same whether installed on a petrol or diesel version of the car.
As with the base version, installing a kit with two generators does not affect the warranty, as it does not require mechanical intervention in the vehicle's components.
Yes, of course. The sound is perfectly audible inside the cabin even at 10-15% volume.
Yes, for this purpose, a separate product – the "Sound Generator" – is available on our website. You can purchase it and connect it to your existing Thunder system, turning it into the flagship version with two generators.
Dzintars
Upgraded from one generator to two – the difference is enormous! The volume and depth that were so lacking appeared. The sound is now more alive and rich. On the Audi A6 it is just a song. Thanks to the team!
Armands
The flagship is the flagship! On the Porsche Cayenne (although it's not on the list, I took a risk) it fit perfectly. The sound is just gorgeous, especially at low frequencies. Vibration and bass are felt throughout the body. I recommend it!
Ugis
For my BMW 7 Series – just what the doctor ordered. In such a large sedan you need voluminous sound, and two generators do an excellent job. Now it's not just a luxury car, but a real sports car at heart.
Raimonds
Best purchase of the year! On the Range Rover Sport the sound has become simply benchmark. Friends are delighted, ask for a ride to listen. Huge thanks to the developers for this product and the instructions with color photos.
Ilmars
Gave myself a Christmas gift. I didn't expect that two speakers could change the perception of the car so much. The Mercedes GLC shone with new colors. The sound is clean, without rattling, perfectly synchronized with the gas pedal.
Aigars
Quality and sound at the highest level! The Mercedes GLE now sounds like a real monster. 100% satisfied. The only downside is the long delivery, had to wait longer than stated. But it was worth it.
Guntis
The kit with two generators is a choice without compromise. On the Audi Q8 the sound is now simply cosmic. Very satisfied with the quality, all wires are long, the units are compact. Now I definitely open the window in tunnels.
Normunds
I doubted for a long time, afraid it would sound like a cheap synthesizer. But Thunder dispelled all doubts. The sound is really cool, voluminous, real. On my BMW X3 it now roars like a beast.
Edgars
Amazing product! On the Lexus RC the sound became even more aggressive and sporty. Two generators give an excellent stereo image. Every time I press the gas pedal to listen to this roar.
Valdis
I installed the Thunder electronic exhaust system with two sound generators — the effect is simply incredible! The car sounds completely different now: the sound has become deep, rich, and truly powerful. Most importantly, with two generators the sound is much fuller and more realistic than I expected. At idle it has a pleasant deep tone, and under acceleration it really comes alive with character, while still sounding refined and without any cheap artificial effect. After the installation, the car started giving me a completely different driving experience. I am extremely satisfied with the purchase — this is exactly the level of sound the car was missing. Definitely recommended!
Andris
After installing Thunder with two sound generators, the car truly came to life. The sound became deep, full, and very impressive. It stays comfortable in the city, but under acceleration it shows real character. I am very satisfied with the result — one of the best upgrades for my car.
Juris
I installed Thunder on a Mercedes S-Class, and the result exceeded my expectations. The sound became deep, refined, and truly fitting for a car of this class. In the city it remains comfortable and unobtrusive, while under acceleration it reveals a powerful and beautiful character. I am very satisfied — the system complements the car perfectly.
Aivars
Very satisfied with the purchase! The Audi A8 has a large cabin, and one generator might not be enough. But two create the perfect sound stage. Now every ride is a pleasure. Quality 10 out of 10.
Peteris
Gave myself a birthday present. On the BMW X6 the sound became just fabulous – deep, bassy, with perfect synchronization with RPM. Two generators are a completely different level!
Richards
I installed Thunder on my Tesla because the total silence eventually started to feel a bit boring. I wanted to give the car more emotion and character, and the result really impressed me. The sound turned out very pleasant, refined, and well-balanced, without being intrusive. The most interesting part is that people around me are genuinely surprised when they see a Tesla with this kind of sound. Now the car feels completely different, and every drive has become much more enjoyable. I am very satisfied with the installation.
Aleksejs
The flagship kit is the bomb! Installed on a Range Rover Velar. The sound now is as if there is a V12 under the hood. Very glad I took the version with two generators – the sound volume is cosmic. The instruction with photos helped.
Kristaps
The system itself is fire! On the BMW X5 the sound is just a fairy tale, two generators work wonders. But delivery let me down – I waited almost a month, although they promised 15-20 days. I take off a star for this. I recommend the product itself!
Martins
This is no longer just an interesting option, but a truly serious upgrade to the driving experience. On the Mercedes GLE, the sound became much deeper, fuller, and richer. My friends are genuinely surprised when they find out that this effect is created simply by sound generators. I was also especially pleased with the build quality — everything is made neatly, solidly, and to a high standard.
Janis
I hesitated for a long time between one and two generators. I decided to take the flagship and haven't regretted it! My Audi Q7 started to sound like a real sports car. The bass gives me goosebumps.
Karlis
Installed on my BMW X5. The sound is simply incredible – voluminous, deep, you feel every note! Two generators give a real presence effect. Thank you!
