GND
Connect the ground terminal with a suitable contact ground point on the vehicle’s chassis. The ground wire must be as short as
possible and must be connected to a blank metallic point at the vehicle’s chassis. Ensure that this ground point has a stable and
safe electrical connection to the negative “–”pole of the battery. Check this ground wire from the battery to the ground point if
possible and enforce it, if required. Use a ground wire with a sufficient cross section (at least 10 mm
2
) and the same size like the
plus (+12V) power supply wire.
LINE INPUTS & INTERCONNECTION

BEFORE THE CONNECTION
For the professional installation of a sound system appropriate wiring kits are available in car audio retailer stores. Attend the sufficient
profile section (at least 10 mm
2
), the suitable fuse rating and the conductivity of the cables when you purchase your wiring kit. Clean and
remove rust-streaked and oxidized areas on the contact points of the battery and the ground connection. Make sure that all screws are
fixed tight after the installation, because loosely connections may cause malfunctions, unsufficient power supply or interferences.
We reccomend therefore the
CRUNCH CR10WK
wirekit.

REM (TURN-ON SIGNAL)
Connect the turn-on signal (e.g. automatic antenna) or the turn-on remote signal of your headunit with the REM-terminal of the
amplifier. Use therefor a suitable cable with a sufficient cross section (0,5 mm
2
). Thereby the amplifier will turn on or off automatically
with your headunit.
BATT+12V
Connect the BATT+12V-terminal with the +12V pole of the vehicle’s battery. Use therefor a suitable cable with a sufficient cross
section (min. 10 mm
2
) and install a additional in-line fuse. For safety reasons the distance between the fuseblock and the battery
must be shorter than 30 cm. Do not install the fuse into the fuseblock until the installation is accomplished.

FUSE
The inserted fuses protect the amplifier from shorts and capacity overload. Please replace defective fuses only by fuses with the
same type and rating.
The
HIGH INPUT
is suitable to connect the amplifier inputs with speaker wires, if your headunit is not equipped with pre-amplifier
RCA outputs.
Extend every regarding speaker cable from your headunit with appropriate speaker cables from your car audio retailer to the
mounting location of the amplifier.
Then connect the each matching loudspeaker cable with the cables of the included HIGH INPUT connector like described below.
Please note that a ground cable (black cable, GND) for the HIGH INPUT must be connected, which you can branch from the
ground terminal of the amplifier (GND).
It is essential to connect both input channels (L+R)
.
After you have connected the cables of the HIGH INPUT connector with the speaker cables, you can insert the connector into
the HIGH LEVEL socket.
NOTE:
Never use the HIGH INPUT and the LOW INPUT at the same time. This may damage the amplifier seriously. The
loudspeaker cables of the HIGH LEVEL INPUT may not be have contact to the ground (GND) by any means.

Connect to
LOW INPUT RCA jacks
by a stereo patch cable with the headunit. Both input jacks must be connected. If only one
input jack is available, you need to use a y-adaptor.
