【AT-AQ474 Door Tuning Starter Kit｜Deadening Material to Reduce Rattling and Sound Leakage Inside the Cabin】

Want to make the sound from your door speakers a bit easier to listen to? Does the area around the door rattle when you turn the volume up? Are you concerned about sound leaking to the outside of the car? If so, the AT-AQ474 Door Tuning Starter Kit is a convenient option.

By absorbing unwanted noises inside the door and shaping areas around the speaker and outer panel, it creates an environment where sound can come together more naturally. The uneven, profiled processing ensures sufficient sound-absorption area, making this material efficient and easy to use even in limited space.

The kit includes materials for the speaker, the outer panel, and point tuning. It’s also suitable for people who want to check the change in sound before performing a full-scale installation across the entire door, or for those who want to slightly refine the sound of their factory speakers.

However, the amount of installation required varies depending on the vehicle model, door structure, and the current condition of the sound. Depending on the vehicle, the kit alone may not be enough, and simply changing where you apply the material can also affect the overall impression of the finish. If it were me, I wouldn’t just stick the materials anywhere—I’d confirm the condition of the speaker and the door first, then apply them selectively to the areas where you want to achieve the effect.

If you’re considering door tuning using the AT-AQ474, please tell us your vehicle model and what you’re currently hearing that you want to improve. We’ll think together from the necessary scope based on your intended use and budget.
