ELECTRICAL INTERCONNECTION
+12V
Connect the +12V terminal with the +12V pole of the vehicle’s battery. Use a suitable cable with a suf-
ficient cross section (refer to the table on the next page).
BEFORE CONNECTING
For the professional installation of a sound system, car audio retail stores offers appropriate wiring kits. Ensure
a sufficient profile section (refer to the table on the next page) and a 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 instal-
lation, because loose connections cause malfunctions, insufficient power supply or interferences.
GND
Connect the GND 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 en-
force it if required. Use a ground wire with a sufficient cross section (refer to the table and the recom-
mendations on the next page) and the same size like the +12V power supply wire.

REM IN/OUT
Connect a turn-on signal or the turn-on remote signal of your head unit (REM) with the REM IN/OUT
terminal of the amplifier. Use therefor a suitable cable with a sufficient cross section (0,5 mm
2
). Hereby
the amplifier turns on or off with your head unit.
If you use the
AUTO TURN-ON
function (refer to page 25, section 15), the REM IN/OUT terminal
does not need to be connected. However, the REM IN/OUT terminal can then connected to the REM
terminal of another amplifier to provide a control signal to it (REM OUT function).
