General instructions: Installation of BRAX amplifiers
To find out how BRAX MX4 works best for you, read this manual carefully and follow the instructions for installation. We
guarantee that this product has been checked for proper functioning before shipping. Before you start installation, discon-
nect the car battery at the minus pole. Once again we would like to urge you to have the installation work carried out by a
specialist, as a verification of correct installation and connection of the unit is a prerequisite for warranty cover of BRAX by

1. Install your amplifier at a dry location in the car where there is sufficient air circulation to ensure adequate cooling of
the equipment. Also ensure that there is sufficient clearance available for making the cable connections and operating the
controlls.
2. For safety reasons the amplifier must be secured in a professional manner. This is performed by means of four fixing
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 amplifiers
The amplifier 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 amplifier 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.
