It´s hardly possible to improve one of the best sounding amplifiers on the market. Nevertheless, GROUND ZERO selected some latest electronical parts and spent hours of listening to improve the parameters in detail! A new and improved pre-amp section, enhanced BIAS range and most of all a better Signal-to-Noise ratio deliver a clearly audible enhancement in Sound Quality of the SQ version.
All you need for an efficient noise reduction of two doors within one package. The new PRO version not only includes 3 different types of damping materials, but in addition two sheets of GZDA 1200AL-GOLD, a pure aluminum plate leading to an increased effect of the overall damping.
All left-hand drive (LHD) Mercedes customers have been offered GROUND ZERO subwoofers to upgrade the OEM sound system already since last year. Now, the line-up has been extended by woofers for right-hand drive (RHD) models, too. The subwoofers are available separately for the driver´s and the passenger´s side.
