Everything is very bad, I do not recommend it, there were problems at all stages of the acoustics installation, the wires were thrown haphazardly, one wire was laid in the rail along which the chair moves. They couldn't screw the rear speakers to the shelf in any way, I left the car for revision several times, they said everything was done, as a result, they say everything is ready, I come and stupidly lift the speaker from the shelf with my hand, I took a thin drill bit and a short screwdriver myself and screwed the rear speakers myself. More than half of the fasteners on one of the doors were broken, and I had to buy a door card.
The guys are great, they are professionals in their field. They know and understand acoustics and sound. The acoustics were clearly and competently selected in the car and installed in a short time.
