[. . . ] Please remember when listening to music in your car that constant sound-pressure levels of more than 100 dB can cause permanent damage to the human ear right up to complete loss of hearing. Sound-pressure levels of more than 130 dB can be achieved with modern high-performance systems and highquality loudspeaker configurations. [. . . ] With regard to accident prevention the Velocity power amplifier must be affixed in a professional manner. The mounting surface must be suitable for accepting the enclosed screws and must offer secure installation. When drilling holes please ensure that no car components are damaged (battery, cables, fuse box). A dry position should be selected for the installation location that guarantees sufficient air circulation for the cooling of the amplifier. Do not connect the loudspeakers to earth, use only the designated terminals. The cross-section of the positive and negative cable may not be less than 16 mm2. Fit a fuse holder to the positive cable between the battery and the amplifier directly at the battery. velocity ReferenceAmplifier VR 502/1002 The amplifier is suitable for connecting to car radios with cinch connector. Use the Blaupunkt ISO-Cinch Adapter for connecting to car radios with ISO connector. The use of the integrated frequency divider is sensible particularly with multipath sound systems with separate subwoofer. [. . . ] Integrated fuses (FUSE) The fuses integrated into the amplifier protect the power amp and the complete electrical system in the event of faults or failures. When inserting a spare fuse, never replace with fuse types with a higher current or bridge fuses. [. . . ]
