INSTALLATION INSTRUCTIONS
16
GND
Connect this 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 electric 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 16 mm
2
) and the same size like the
plus (+12V) power supply wire.
REM
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.
+12V
Connect the +12V-terminal with the +12V pole of the vehicle’s battery. Use therefor a suitable cable with a sufficient cross section
(at least 16mm
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. Replace damaged fuses only with equal fuses with
the same fuse rating (check the specifications).
AUTO TURN ON & INPUT LEVEL MODE
If your headunit doesn’t provide a separate remote turn on wire (like described under #2) and has no pre-amplifier low level RCA
outputs, follow these instructions:
Push the
AUTO TURN ON
button to position
ON
to activate the auto turn on function. This function only works, if the push button
INPUT LEVEL MODE
is in
HI
position and highlevel inputs (speaker outputs from the headunit) are connected at the
LINE IN
.
Please check the regarding notes below.
The amplifier detects now by the so called ”DC Offset” (a voltage increase to 6 volts on the high level speaker outputs) if the
headunit is turned on and the amplifier turns automatically on. As soon as the headunit is turned off, the amplifier shuts down
automatically after approx.one minute.
NOTE:
The AUTO TURN ON usually works with 90% of all headunits, because the arey equipped with the ”High Power” outputs.
Only with a few older headunits the AUTO TURN ON function is not applicable.
The port of the remote connector of the amplifier (#2, REM) can now be used also to turn on additional other amplifiers. Connect
the REM ports of the amplifiers and ensure, that the other amplifier’s AUTO TURN ON function is deactivated.

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 16 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, insufficient power supply or interferences.

To connect the high level speaker cables of the headunit
follow these instructions:
Crimp and solder the ends of the loudspeaker cables of the
headunit with common RCA connectors (separately available)
and connect them with
LINE IN
of the amplifier.
You can simplify the installation, if you use the separately available
hi-to-lo adaptors
HF-HLA
from
HiFonics
(see page 21).
