[. . . ] 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. If you 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. For the connection to car sound systems with ISO connection, use Blaupunkt ISO cinch adapters (7 607 893 093 or 7 607 855 094).

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: 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. (If the amplifier is to be jumpered, continue with the section "Bridged loudspeaker connections" at this point). As with every audio component, the correct polarisation of amplifier and loudspeakers is of essentially importance for a good bass response. For this reason, ensure that the positive (+) connection of the amplifier is connected with the positive connection (+) of the loudspeaker; the same applies to the negative (-) connections. In addition, the left amplifier channel must be connected with the left loudspeaker and the right amplifier channel with the right loudspeaker. [. . . ] For example, if a pair of subwoofers is to be connected, the low-pass settings shown are required (Fig. Please use the return and collection systems available to dispose of the product.
