Improving Car Audio

What is the problem?
Since the speakers cause the sheet metal of the doors to resonate, music is not cleanly being reproduced and sheet surfaces can even start to vibrate with the music, resulting in negative noise. Doors or doors that have not been "de-drummed" give music a hollow sound, especially in the reproduction of bass sound.

What is the solution?
The solution is comparable to insulating doors. By covering the doors on the inside with anti-drumming mats, the plate surface is held in place, as it were. Resonances disappear and the music reproduction becomes cleaner and fuller. With very heavy audio installations (competitions), higher volumes are measured in the vehicle, because of a reduction in sound leakage.


Provide the outside plate of the door on the inside with anti-drumming mats such as STP Standardplast or Vibraflex Extreme. For the ultimate effect, also coat the inner plate to which the cladding panel is attached. The side panels next to the door can also be muted with these materials, because loudspeakers are often mounted there.

Which products do I use and where?

The difference between Vibraflex and STP Standardplast is that the STP products are made of butyl rubber, which makes the product a bit more expensive, but major advantages are the remarkable flexibility at lower temperatures and how easy it is to cut it to size.
