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.
The M-400.1 mD + co-220.1 have a remote out (RO) for additional amplifier.
When using High-Level-Inputs the remote connection is not neccessary.
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.
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 7-5).
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 in a way so that there is no danger of binding,
squeezing or breaking.
Please follow the instructions during the installation of your amplifier:
