ELECTRICAL INTERCONNECTION
BEFORE CONNECTING
For the professional installation of a sound system, car audio retail stores offers appropriate wiring kits. Ensure
a sufficient profile section (at least Ø 2,5 mm), 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 installation, because loose
connections cause malfunctions, insufficient power supply or interferences.
POWER
Connect the POWER +12V terminal (+12V) with the +12V pole of the vehicle’s battery. Use a suitable
cable with a sufficient cross section (at least Ø 2,5 mm) and install an additional in-line fuse. For safety
reasons the distance between the fuse block and the battery should be shorter than 30 cm. Do not set
in the fuse into the fuse block until the installation is accomplished.
Connect the POWER GND terminal (– ground) 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 Ø 2,5 mm) and
the same size like the po power supply wire. This helps reduce most of the interference than
can occur in audio reproduction.
REM IN is suited to turn on the device if a turn-on signal from the head unit/car stereo is available. The
voltage must be between 7 and 15 VDC. For that the switch POW ON SEL must be in position REM.
REM OUT can be used to connect another device such as an amplifier in order to supply it with a
turn-on signal (REM OUT function).

Make sure the connection polarity is as indicated on the terminals. A misconnection may
result in damage to the device. After applying power, wait about 8 seconds before turning
the device on.
