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 cab-
ling 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 excep-
tion 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 mm
2
. For the X 1400 BRAX ampli-
fiers described, we recommend a minimum cross section
of 12 mm
2
/gauge 7, and for the X 2400 a minimum cross
section of 20 mm
2
/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 repro-
duction, 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 mm
