In order to upgrade the basic version of the factory-installed audio system of a Mercedes listed in the compatibility chart,
GROUND ZERO offers a specially tailored speaker system matching these models as well as matching woofers for the original slots.
Due to the specific design, no change to the original wiring is necessary.
Therefore, such an upgrade can later be restored, easily if required.
