    Very professional work and an excellent result. They installed a sound system in a Mercedes Viano camper, and the acoustics and sound detail are now on a completely different level! It's almost on par with what I hear at home from quality speakers. The subwoofer is perfectly chosen, just right for my taste. Everything was done extremely carefully, with no extraneous noises or plastic rattling, and the wiring and integration are flawless. True professionals in their field, I recommend them.

    I upgraded the original audio system in my Alfa Romeo SUV. We started with sound insulation and front door speakers with an amplifier. We finished with an additional amplifier with DSP and professional tuning :) The result exceeded all expectations. I've been using it for a year now and don't want to get out of the car :) The work was done super PRO. When questions or options came up along the way, they discussed them with me, consulted and advised. The best investment and modification I've ever made to a car, and I don't regret a single euro. Highly recommend

    Excellent service! The "Autogarso" team quickly and professionally installed a dash cam in my car. I especially want to thank administrator Robertas for his pleasant communication, thorough consultation and attentive approach to the customer. I recommend it to everyone looking for reliable car electronics specialists.

    I had sound and vibration insulation installed in the doors, wheel arches, trunk, and under the rear seat. The result was really noticeable. BMW g31
