3. +12 V Power connection (+24 V in co- 75. 4 24 V) :
Connect the +12 V (+24 V in co- 75. 4 24 V) contact of the amplifier with the supply cable via a fuse directly
to the vehicle battery. Keep in mind, that the length of the cable from fuseholder to vehicle battery has to be a
maximum of 30 cm. Requirement for a perfect function of the amplifier is a qualitative high end fuse holder as well
as a suitable cable cross section (AWG sice 8 - 6). This fuse protects the amplifier and the vehicle against the
possibility of a short circuit in the power cable.
4. Remote connection
Connect the REM-terminal of the amplifier to the remote-output (automatic 12 V (+24 V bei co- 75. 4 24 V)
antenna-output) of the head unit. Therefore use a 0,5 - 1,5 mm power cable.
Please follow the instructions during the installation of your amplifier:
a) Take care of a professional attachement. Pay attention, that no electrical cable, gas tank, hydraulic
breakes or other components get damaged.
b) There has to be enough cooling and air circulation. Avoid the installation in small closed boxes or close
to heatening parts.
c) Protect the amplifier from fluids, wetness, heat and foreign material as well as from other influences.
d) The amplifier is only to be built into vehicles with a 12 V DC (+24 V in co- 75. 4 24 V)
power supply.
e) Never install the power supply cable with other original wires of the vehicle (gas cables), fan motors,
brand control moduls etc.
f) Install the signal cable (cinch cable) as well as the speaker cable far away of the power cables to avoid
troubles with the music signal.
g) The cables of your amplifier have to be installed, so that there is no danger of binding, squeezing or
breaking.

1. Battery disconnection
First disconnect the power supply of the vehicle.
This works out the best by removing the ground
cable of the battery.
2. Ground connection
Connect the GND (ground) connection of the
amplifier with the car chassis. Keep this cable
as short as possible (not longer than 50 cm) and
use a suitable cross section (AWG sice 8 - 6).
Make sure, that the connection with the vehicle
chassis is free of paint, dirt and dust.
