[. . . ] The performance of an amplifier can only be as good as its installation. A correct installation increases the overall performance of your car sound system. Would to install it yourself, please read these installation instructions very carefully and allow yourself sufficient time for the installation. [. . . ] The amplifier is suitable for connecting a car sound system with cinch connections. - Securely fasten commercially available minus cables to a noise-free earth point (chassis screw, chassis metal) (not to the minus pole of the battery). - Scrap the contact surfaces of the earth point until they are bright and grease with graphite grease. Caution: When making the connection, always set the volume control to minimum and switch off the amplifier. The fuses integrated in the amplifier (Fuse) protect the power amplifier and the entire electrical system in case of an error. If a replacement fuse is used, never bridge fuses or replace them with a type with higher current. The Level control is used to adjust the input sensitivity of the power amplifier to the output voltage of your car sound system preamplifier output. If a car sound system of a third party manufacturer is connected, the input sensitivity must be adjusted corresponding to the manufacturer data. A few important explanations in this context: This allows the amplifier to be switched on and off using the on/off-switch of the radio device. The amplifier is equipped with high-level inputs to permit connection to radios without preamp outputs (Fig. This enables direct connection to be made to the radio's loudspeaker output. By turning the control clockwise, the input sensitivity of the amplifier and, therefore, also the volume increases. However, this is not a volume control; no further amplifier output can be achieved in the end position, even if it may sound like that at the beginning. The system merely increases the volume faster if the volume control of the car sound system is turned up.

Låt oss bara till sist säga några ord om hälsoskydd: Tänk på om du lyssnar på musik i bilen att en långvarig ljudnivå över 100 dB kan leda till bestående hörselskador och till och med dövhet. Därför är det viktigt att vid anslutning se till att den positiva anslutningen (+) på förstärkaren är kopplad till högtalarens positiva anslutning (+). [. . . ]
