Installing the BRAX Amplifiers
In order to maintain the quality of this product and ensure safe operation, we recommend that our amplifiers be installed by an authorized BRAX dealer. Installation by a qualified and accredited technician will qualify you for our special lifetime warranty. Your BRAX dealer will also assist you in selecting the correct additional components and in ensuring that proper consideration is given to all the safety and sound-related aspects.
Important:
Before commencing installation, disconnect the car battery at the negative terminal. Once again we would urge you to have the installation work carried out by a specialist, as verification of correct installation and connection of the unit is a prerequisite for warranty cover of the BRAX by AUDIOTEC FISCHER Germany.
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 controls.
2.
For safety reasons, the amplifier must be secured in a professional manner. This is performed by means of four fixing screws (see Fig. 2) screwed into a mounting surface offering sufficient retention and stability. 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/moldings.

Installation and Connection of BRAX Amplifiers X 1400 and X 2400
The above amplifier models may only be installed in motor vehicles which have a 12-volt 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 amperage rating of the fuse is calculated from the maximum total current input of the car/vehicle hifi system.
Never bridge fuses or replace them with fuses with a higher amperage rating as such actions could lead to the destruction both of the amplifier and the entire electrical system of the vehicle.
As already mentioned, the negative lead from the vehicle battery to the chassis should be disconnected in order to prevent the occurence of short-circuiting. Install the cabling in a manner which precludes any danger of the leads being exposed to shear, crushing or rupture forces. If there are sharp edges in the vicinity (e.g holes in the body work), all the cables must be cushioned and protected to prevent fraying.
Never lay the power supply cables adjacent to leads and lines connecting other vehicle equipment (fan motors, fire detection modules, gas/petrol lines etc.).
In order to avoid cross-talk distortion, audio cables should never be laid together with electrical leads (with the exception of the screened BRAX POWER TRAX power supply cables).
In order to ensure safe installation, use only high-quality connection materials, and comply with the recommended minimum cross sections/gauge values of the cables for the individual amplifier modules.
As an aid to calculating the cross-sectional requirements of power cables which are not longer than 5 m, we advise a figure of max. 5 A per mm2. For the X 1400 BRAX amplifiers described, we recommend a minimum cross section of 12 mm2 /gauge 7, and for the X 2400 a minimum cross section of 20 mm2 /gauge 5 for the positive 12-volt supply lead and for the ground (chassis) cable. In order to ensure optimum sound quality and interference-free music reproduction, we recommend that installation be performed with BRAX POWER TRAX power supply cables. The remote lead should have a cross section of at least 1 mm2.
