Mounting
Important note! In order to replace the original speaker, panels or covers need to be removed. This may require special lever tools in order not to damage the fastening clips on the panels. Therefore, it´s strongly recommended only having the components installed by a car audio workshop or similar specialists having the necessary tools available and sufficient experience in installing such components in order to avoid any damage to the trim parts, bodywork, paintwork or electrical equipment of the vehicle due to an incorrect or inaccurate installation.
Respect the Music
Listening to music can be emotional, impressive, relaxing or enjoyable. At that, it doesn´t really matter what kind of music is the personal favorite, whether it´s Instrumental, Jazz, Electro, Latin, Classic, Rock or any other music direction. However, audio reproduction quality at each desired volume is elementary. Some music styles require higher levels while others prefer the soft tones. GROUND ZERO considers all the different wishes of customers during the development of new products. Along with this, the target is to create the most realistic sound, to transfer the soul of the music and the intention of the performer. Summarized to one phrase: RESPECT THE MUSIC!
