1. Install your amplier at a dry location in the car where there is sufcient air circulation to ensure adequate cooling of
the equipment. Also ensure that there is sufcient clearance available for making the cable connections and operating the
controls.
2. For safety reasons the amplier must be secured in a professional manner. This is performed by means of four xing
screws screwed into a mounting surface. Before drilling the holes for the screws, carefully examine the area around the
installation position and make sure that there are no electrical cables or components, hydraulic brake lines or any part of
the petrol tank located behind the mounting surface - otherwise these could be damaged. You should be aware of the fact
that such components may also be concealed in the double-skin trim panels/mouldings.
General instructions: Connection of BRAX ampliers
The amplier may only be installed in motor vehicles which have a 12V negative terminal connected to the chassis ground.
Any other system could cause damage to the amplier and the electrical system of the vehicle. The positive lead from the
battery for the complete system should be provided with a line fuse at a distance of max. 30 cm from the battery. The am-
perage rating of the fuse is calculated from the maximum total current input of the car/vehicle audio system.
