MDF Speaker Adapters BMW 1 3 Series Z4

These speaker adapters are made in Europe. In their production we use the best quality MDF from well-known brands. Thanks to the rigid construction, our MDF frames guarantee the best sound quality from the speaker. The speaker hoops are already impregnated to keep them protected from moisture. They are impregnated in a black color that makes it invisible through the grille. Before the entire installation process, you will need to drill holes in the speaker hoops. Make sure you use the right drill bit to do this.
