ELECTRICAL INTERCONNECTION
Installation of RCA/Audio signal cables and power supply.
Please install if possible the audio cables from the headunit and the amplifier not together with the power
supply wires on the same side of the vehicle. The best is an areal separated installation in the left and right
cable channel of the vehicle. This avoids an overlap of interferences on the audio signal. This also applies
for the supplied bass-remote connection, which should not be installed together with the power supply
wires. It is recommended to use the same side like the audio cables.
REFERENCE NOTE
INSTALLATION INSTRUCTIONS
BATT+12V
Connect both BATT+12V-terminals with the +12V pole of the vehicle’s battery. Use a suitable cable with a sufficient cross section
and install an 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.
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.
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.
LOGO BADGE
With this switch you can choose between white or blue illumination of the upper logo badge.
Always follow the guidelines of your national road traffic regulations.

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 (attend the specifications below), 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.

IMPORTANT NOTE: Due to the very high power consumption, the X4-COLOSSUS model has two power terminals, which
must be both connected. Furthermore we suggest the installation of an additional battery. Please use a power wiring
with a crosssection of at least 2 x 35mm
2
in 4 ohm-operation.
IMPORTANT NOTE: The X4-COLOSSUS model has due to construction-conditioned reasons no internal fuse-protection.
The amplifier must be fused with an external In-Line-Fuse aan the following fuse values:
200 A in 4 Ohm-operation
300 A in 2-Ohm-operation
400 A in 1 Ohm-operation
