“Just pasting it on” is not enough. Change the sound, quiet your car, and add real deadening to your door.

[Our specialty deadening construction that seriously changes the sound]
For those of you who are not satisfied with just filling the service hole.
Our deadening is a higher-grade construction that allows you to experience improved sound quality, quietness, and reduced sound leakage.

The amount of damping material used is approximately 1.5 times the amount of damping material used for general plans. The backside of the door is thoroughly treated to bring out the full performance of the speaker.
It suppresses road noise and vibration while driving, and transforms the inside of the car into a clear space that feels like a listening room.

We want people to understand the value of better sound because it's a car that enjoys music---
That's our idea behind Deadning.
