Hello! Since the doors in my car are not yet insulated, I wanted to make up for this over Christmas. I am now faced with the decision whether to do it with Brax eXvibration, or with Sinus Live MXM bitumen mats. Does price-wise come out about the same thing. My question is now what is more effective of the two things. Problem at my front installation is that the speakers with the doorboards are fixed on the original door boards and thus also a bit resonant. ill ill minimize, i.e. “stiff” the door boards especially with the insulation material. Doorboards are by the way the cheap Phonocar dinger, because I am not very skilled in craftsmanship and unfortunately I also lacked the right tool to build them myself. I am grateful for every tip. By the way, you can take the installed components from my signature.
