【AT-AQ405 Deadening Kit for Door Tuning】

This is a damping, absorption, and soundproofing material kit for 2 door panels, designed for those who want to hear their door speakers a bit more clearly and for those who notice vibrations and resonance around the doors when they turn the volume up.

AT-AQ405 is characterized by the fact that it comes with all the materials you need for door tuning. For the damping material, it uses virgin butyl rubber with a high density of 1.8, which is easy to work with. It provides a solid base to suppress unnecessary door vibrations while helping the sound produced by the speaker reach the cabin as efficiently as possible.

It also includes three types of soundproofing materials for filling the gaps between the inner panel and the door trim, as well as an absorption material to reduce unwanted reflections of sound coming from the speaker. This kit is suitable for those who want not only to add materials in selected spots, but also to apply them in a balanced way while checking the condition of the entire door.

However, deadening does not deliver the same result just by sticking the materials. Because different vehicle models have different door structures, the position of the OEM speakers, and the shapes of the service holes, the overall impression of the finish will vary depending on where and how much material you apply, and how you process it. If it were me, I would first check the vehicle and the current state of the sound, then install the materials properly where they are needed. It is also important not to use too much material so the door becomes heavier or causes problems during later maintenance.

Whether your goals are to “tighten the bass a little more,” “make vocals easier to hear,” or “prepare the door before replacing the speakers,” we consider the best direction together based on the vehicle model, how you use it, and your budget.
