INTERCONNECTION AND INSTALLATION SHOULD BE ACCOMPLISHED BY SKILLED STAFF ONLY. The interconnection and installation of this device demands technical aptitude and experience. For your own safeness, commit the interconnection and installation to your car audio retailer, where you have purchased the device.
DISCONNECT THE GROUND CONNECTION FROM THE VEHICLE’S BATTERY BEFORE
INSTALLATION.
Before you start with the installation of the sound system, disconnect by any
means the ground supply wire from the battery, to avoid any risk of electric
shock and short circuits.
CHOOSE AN APPROPRIATE LOCATION FOR THE INSTALLATION OF THE DEVICE. Look for an appropriate location for the device, which ensures a sufficient air circulation. The best places are spare wheel cavities, and open spaces in the trunk area. Less suitable are storage spaces behind the side coverings or under the car seats.
DO NOT INSTALL THE DEVICE AT LOCATIONS, WHERE IT WILL BE EXPOSED TO HIGH HUMIDITY AND DUST. Install the device at a location, where it will be protected from high humidity and dust. If humidity and dust attain inside the device, malfunctions may be caused.
MOUNT THE DEVICE AND OTHER COMPONENTS OF THE SOUND SYSTEM SUFFICIENTLY. Otherwise the device and components may get loose and act as dangerous objects, which could cause serious harm and damages in the passenger room.
ENSURE CORRECT CONNECTION OF ALL TERMINALS. Faulty connections may could cause fire hazard and lead to damages of the device.
MOUNT THE DEVICE AND OTHER COMPONENTS OF THE SOUND SYSTEM SUFFICIENTLY. Otherwise the device and components may get loose and act as dangerous objects, which could cause serious harm and damages in the passenger room.
ENSURE NOT TO DAMAGE COMPONENTS, WIRES AND CABLES OF THE VEHICLE WHEN YOU DRILL THE MOUNTING HOLES. If you drill the mounting holes for the installation into the vehicle’s chassis, ensure by any means, not to damage, block or tangent the fuel pipe, the gas tank, other wires or electrical cables.
DO NOT INSTALL AUDIO CABLES AND POWER SUPPLY WIRES TOGETHER. Ensure while installation not to lead the audio cables between the head unit and the processor 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.
ENSURE THAT CABLES MAY NOT CAUGHT UP IN CLOSE-BY OBJECTS. Install all the wires and cables like described on the following pages, therewith these may not hinder the driver. Cables and wires which are installed close-by the steering wheel, gear lever or the brake pedal, may caught up and cause highly dangerous situations.
DO NOT SPLICE ELECTRICAL WIRES. The electrical wires should not be bared, to provide power supply to other devices. Otherwise the load capacity of the wire may get overloaded. Use therefor a appropriate distribution block. Otherwise fire hazard and risk of electric shock consists.
DO NOT USE BOLTS AND SCREW NUTS OF THE BRAKE SYSTEM AS GROUND POINT. Never use for the installation or the ground point bolts and screw-nuts of the brake system, steering system or other securityrelevant components. Otherwise fire hazard consists or the driving safety will be derogated.
ENSURE NOT TO BEND OR SQUEEZE CABLES AND WIRES BY SHARP OBJECTS. Do not
install cables and wires not close-by movable objects like the seat rail or
may be bent or harmed by sharp and barbed edges.
If you lead a wire or cable through the hole in a metal sheet, protect the
insulation with a rubber grommet.
KEEP AWAY SMALL PARTS AND JACKS FROM CHILDREN. If objects like these will be swallowed, the risk of serious injuries consists. Consult promptly a medical doctor, if a child swallowed a small object.
MECHANICAL INSTALLATION
- Avoid any damages on the components of the vehicle like air bags, cables, board computer, seat belts, gas tank or the like.
- Ensure that the chosen location provides a sufficient air circulation for the device. Do not mount the device into small or sealed spaces without air circulation near by heat dispersing parts or electrical parts of the vehicle.
- Do not mount the device on top of a subwoofer box or any other vibrating parts, whereby parts could loosen inside.
- The wires and cables of power supply and the audio signal must be as short as possible to avoid any losses and interferences.
WARNING
Before you start with the installation, disconnect necessarily the GROUND
connection wire from the battery to avoid any risk of electric shocks and
short circuits.
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
positive + 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).
WARNING
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.
