ELECTRICAL INTERCONNECTION

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 10 mm
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
HiFONICS HF10WK wirekit.
GND
1
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 10 mm
REM (TURN-ON SIGNAL)
2
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
headunit.
BATT+12V
3
Connect the BATT+12V-terminal with the +12V pole of the vehicle's battery. Use therefor a suitable cable with a sufficient cross section
(min. 10 mm
) and install a additional in-line fuse. For safety reasons the distance between the fuseblock and the battery must be shorter
2
than 30 cm. Do not install the fuse into the fuseblock until the installation is accomplished.
FUSE
4
The inserted fuse protects the amplifier from electrical shorts and capacity overload. If you need to replace the factory-provided fuse
observe by any means to keep the same fuse rating (15 A).

REFERENCE NOTE

Before you start with the installation of the sound system, disconnect by any means the GROUND connection wire
from the battery, to avoid any risk of electric shock and short circuits.
