Having disassembled the roof, we see sound-absorbing material. It does not cover the surface completely, i.e. the installation rules are violated. We remove it, clean and degrease the surface.
The second layer is sandwich materials: under the front seats and in the center - Sonora, under the rear seats - Bromo. These materials combine the functions of sound insulation and sound absorption.
We treat the trunk, including the wheel arches, with StP Gold
The second layer is made of Bromo sandwich material, which simultaneously functions as a sound absorber and sound insulator.
We disassemble the doors and see the factory vibration insulation. As before, we remove it, clean and degrease the metal.
We roll the StP Gold vibration damper onto the metal. It eliminates vibrations and improves the sound quality from the speakers.
The second material we install is Sonora sandwich material, which provides sound absorption and sound insulation.
