ELECTRICAL INTERCONNECTION
Installation of RCA/Audio signal cables and power supply.
Attend while installation not to lead the audio cables between the headunit and the amplifier together with
the power supply wires on the same side of the vehicle. The best is a areal separated installation in the
left and right cable channel of the vehicle. Therewith a overlap of interferences on the audio signal will be
avoided. This stands also for the equipped bass-remote wire, which should be installed not together with
the power supply wires, but rather with the audio signal cables.
REFERENCE NOTE
FUSE
The inserted fuses protect the amplifier from shorts and capacity overload. Replace damaged fuses only with equal fuses with
the same fuserating (attend the specifications).
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 (at least 35 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.
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.
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 35 mm
2
) and the same size like the
plus (+12V) power supply wire.
LOGO BADGE
With this switch you can choose between white or blue illumination of the upper logo badge. Attend by any means the directives
of your national road traffic regulations.
PROTECT BRIDGE
If you would like to operate two similar amplifiers in the MASTER/SLAVE mode, connect both amplifiers with the appropriate
enclosed cable on the PROTECT BRIDGE port of each amplifier. This connection ensures in case of a malfunction or a defect
on one of the amplifiers (Master or Slave), that both amplifiers will run into the protection mode and shut down.

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 35 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 CR35WK
wirekit.
