Installation
Fasten amplifier to a suitable, well-ventilated location in the vehicle, if possible to the auto body,with included
sheet metal screws and insulated washers.
The amplifier’s heatsinkcan get very hot, making sufficient distance to temperature sensitive parts absolutely
necessary.
Caution:
Clamp the negative pole of the battery before working on connections. This work requires expertise
and should be performed with careful consideration to the relevant safety regulations.
Before connecting the power supply and loudspeaker cables all screws on the amplifier terminal block must be
unscrewed in an upward direction, so that the screws do not obstruct the path of the cables. Under no circumstances
should screws be completely unscrewed, however.
Caution:
Important Safety Notice Concerning Risk of Fire and Injury.
Unscrewing or turning of the screws on the amplifier terminal block during active amplifier operation
(amplifier is performing) is not permitted, as the risk of a short circuit between the screw driver and
the heatsinkcannot be excluded, thus making extreme damage to the amplifier or car, or a burn injury
caused by the electrical current on the screw driver, unavoidable.
Drilling out the amplifier terminal block for the purpose of cross-section extension for cable insertion
can cause damage to the electronics and will result in an immediate voiding of the warranty.
