3. +12 V Power connection:
Connect the +12 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 maximum 30cm. For the amplifier to
function at its best, use a high quality fuse holder and suitable cable preferably AWG 8-6 cable. 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 antenna-output) of the head unit.
Use a 0,5 - 1,5 mm power cable.
1. Battery disconnection:
First, disconnect the power supply of the
vehicle 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 size 8-6).
Make sure, that the connection with the
vehicle chassis is free of paint, dirt and
dust.
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 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.
Please follow the instructions during the installation of your amplifier:
ATTENTION

X-150.2 D
X-150.2 D
The X Series amplifier offers RCA-Inputs, which are connected through cinch cables with the preamplifier-
outputs of the head unit. If the head unit (OEM-RADIO) has no RCA-Output, than it is possible to connect the speaker
output direct to RCA/Cinch-Input. Important: the Gain-Controller has to be adjusted to minimum, then carfully turn up
the volume. Input Mode has to be switched on „HI“. If signal is presented, the amplifier automacally turns on.
Adaptercable HLAC and RCA HI can be purchased at your specialized dealer. The RCA-outputs provide the
possibility to transfer the signal of the head unit to a 2. amplifier via a cinch cable (not possible for x-80. 4 D).
With the aid of the shiftable high- and low pass filter, the gain-controller and the bassboost you are able to adjust the
amplifier on to your prefered taste of hearing, the circumstances of the vehicle and to the speakers.
In this regard, AUDIO SYSTEM germany recommends to adjust your amplifier through a specialized
service center, dealer or a specialist.

trouble shooting
This power amplifier is featured with an efficient protection system to prevent any damages like over-heating,
overvoltage, short-circuit and DC at the loudspeaker output.
Occuring an error the protection-LED will light in red. In order to check the problem, first turn down all levels of
the head unit, afterwards turn it off.

Please contact your specialized dealer if the amplifier is still not working after it has been
checked with the error list!
For warranty adjustement / repairs the original invoice has to be attached!
Opening the power amplifier is leading to a lost of warranty in either case!
