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 danger-
ous 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 re 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 re 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 sufcient air circulation for the amplier. 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 amplier 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.

ENGLISH
ELECTRICAL INTERCONNECTION
BEFORE CONNECTING
For the professional installation of a sound system, car audio retail stores offers appropriate wiring kits. Ensure a sufcient prole section (at least Ø 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 xed tight after the installation, because loose connections cause malfunctions, insufcient power supply or interferences.

FUSE
1
The inserted fuse (30 A blade) protects the amplier from shorts and capacity overload. If you need to
replace the fuse, make sure to use the same type of fuse with the same rating.
POWER
2
Connect the POWER + terminal (+12V) with the +12V pole of the vehicle’s battery. Use a suitable cable with a sufcient cross section (at least Ø 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 – 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 sufcient cross section (at least Ø 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.
NOTE: If you use this POWER terminals instead of the power supply of the System Connector, please remove the in-line fuse (20 A) from the ISO Cable Harness at the System Connector.

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

ENGLISH
SYSTEM CONFIGURATION
In order to congure the inputs, amplied speaker outputs and pre-amplied power outputs, EQ and time delays for the amplier, it must be interfaced with the PC. When you get to this point you must already be
aware of what type of system you intend to set up. In order to avoid complications in preparation, make sure
the following points before you start:
• The type of signals that will be assigned to the inputs (e.g.: front left or center or subwoofer, etc.).
• The speakers in the system (e.g.: 3-way front or sub stereo or 2-way rear, etc.).
• If there are passive crossovers that manage groups of speakers (e.g.: 3-way systems with active midrange).
• If you intend to use an external mono amplier to drive a subwoofer.
• If you intend to use the amplied outputs of the amplier bridged (BLT mode), thus increasing the power on the output.
WARNING
Before turning on the system, set the head-unit output level to a lower level (approximately 20% of its maximum excursion) to avoid damaging the speakers during calibration.
