Congratulations on your purchase of your new

rseries / mseries amplifeier

Before installation your power amplifier, we recommend to read the
manual's owner carefully and to follow the instructions regarding connection and
fitting exactly.
We advice to accomplish the installation by an authorized service center, because
a professional fitting and connection is the requirement for further warranty
adjustments.

Power connection

R+M

r 100.4 / R 190.2 / m 75.4 / m 130.2

1. Battery disconnection

GND

REM

+12V

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 7-5).
Make sure, that the connection with the
vehicle chassis is free of paint, dirt and
dust.

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 7-5 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.

5. HI/LOW selectable button

If the radio (normally original radio) has noh RCA output and remote output (automatic 12 V antenna
output) it is possible to connect the speaker output from headunit direct in RCA input. The HI/LOW
button must be switched to „HI“ (picture on page 4). If the X SERIES amplifier get a signal from
head unit output, the amplifier will turn on.

Caution

Please take the following precautions when installing your amplifier:

a) Take extra care when making the connections. Make sure that no electrical cable, gas tank,

hydraulic brakes or other components get damaged.
b) Allow enough cooling and air circulation and avoid installing the unit in small closed boxes
or close to parts that heats up easily.

c) Keep the amplifier away from liquid, moisture, heat and foreign materials.
d) This amplifier can only be used in vehicles with 12V DC power supply.
e) Never install the power supply cable with other original vehicle wires (gas cables), fan motors,

control modules etc.
f) Install the signal cable (cinch cable) as well as speaker cable far away from the power cables
to avoid interference with music signals.
g) To avoid dangers of cables binding, squeezing or breaking, use the cables supplied with
your amplifier.
