ENGLISH
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 distribu-
tion 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 security-
relevant 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.

ENGLISH
MECHANICAL INSTALLATION
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.
WARNING
• 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.

ENGLISH
ELECTRICAL INTERCONNECTION
FUSE
The inserted fuse (40 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.
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 bat-
tery 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.
POWER
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 chas-
sis. 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.

SYSTEM CONFIGURATION
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.
WARNING
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.

DAS VON IHNEN ERWORBENE GERÄT IST NUR FÜR DEN BETRIEB AN EINEM 12-V-BORDNETZ EINES
FAHRZEUGS AUSGELEGT. Andernfalls besteht Feuergefahr, die Gefahr eines elektrischen Schlages oder
anderer Verletzungen.
BITTE KEINE BEDIENUNG DES SOUNDSYSTEMS AUSFÜHREN, WELCHE VOM SICHEREN LENKEN
DES FAHRZEUGS ABLENKEN KÖNNTE. Führen Sie keine Bedienungen aus, die Ihre Aufmerksamkeit län-
gere Zeit in Anspruch nehmen. Stoppen Sie besser das Fahrzeug an einer sicheren Stelle am Straßenrand,
bevor Sie solche Bedienungen ausführen. Andernfalls besteht Unfallgefahr.
DIE LAUTSTÄRKE NUR SO HOCH EINSTELLEN, DASS SIE WÄHREND DER FAHRT NOCH AUSSENGE-
RÄUSCHE WAHRNEHMEN KÖNNEN. Hochleistungsaudiosysteme in Fahrzeugen, können den Schallpegel
eines “Live-Konzertes” erzeugen. Dauerhaft extrem lauter Musik ausgesetzt zu sein kann den Verlust des
Hörvermögens oder Hörschäden zur Folge haben. Das Hören von lauter Musik beim Autofahren kann Ihre
Wahrnehmung (Warnsignale) beeinträchtigen. Im Interesse der allgemeinen Sicherheit empfehlen wir das Mu-
sikhören beim Autofahren mit geringer Lautstärke. Andernfalls besteht Unfallgefahr.
LÜFTUNGSÖFFNUNGEN UND KÜHLKÖRPER NICHT ABDECKEN. Andernfalls kann es zu einem Wärme-
stau im Gerät kommen und es besteht Feuergefahr.
DAS GERÄT AUF KEINEN FALL ÖFFNEN. Andernfalls besteht Unfallgefahr, Feuergefahr oder die Gefahr
eines elektrischen Schlages. Das Öffnen des Gerätes hat auch einen Garantieverlust zur Folge.
SICHERUNGEN IMMER DURCH SOLCHE MIT DER RICHTIGEN AMPEREZAHL ERSETZEN. Andernfalls
besteht Feuergefahr oder die Gefahr eines elektrischen Schlages.
DAS GERÄT NICHT WEITERBENUTZEN, WENN EINE FEHLFUNKTION AUFTRITT, DIE NICHT VON IH-
NEN BEHOBEN WERDEN KANN. Beachten Sie dazu den Abschnitt FEHLERBEHEBUNG. Andernfalls kann
es zu Verletzungen oder Schäden am Gerät kommen. Geben Sie das Gerät zu Reparaturzwecken an einen
autorisierten Händler oder den nächsten Kundendienst.
DIE INSTALLATION EINES PUFFERKONDENSATORS MIT AUSREICHENDER KAPAZIÄT WIRD EMP-
FOHLEN. Hochleistungsverstärker verursachen sehr hohe Spannungsabfälle und benötigen eine sehr hohe
Stromstärke bei hoher Leistung. Um das Bordnetz des Fahrzeuges nicht übermäßig zu belasten, wird die
Installation eines Pufferkondensators (auch Pufferelko, Powercap oder Power Capacitor genannt) empfohlen,
der parallel zum Verstärker und zur Stromquelle als Puffer fungiert. Lassen Sie sich am besten im Car Audio
Fachhandel beraten.
VERKABELUNG UND EINBAU VON FACHPERSONAL AUSFÜHREN LASSEN. Die Verkabelung und der
Einbau dieses Gerätes erfordern technisches Geschick und Erfahrung. Zu Ihrer eigenen Sicherheit sollten Sie
Verkabelung und Einbau dem Händler überlassen, bei dem Sie das Gerät erworben haben.
VOR DER INSTALLATION DAS KABEL VOM MASSEPOL DER BATTERIE ABKLEMMEN. Bevor Sie mit
der Installation des Soundsystems beginnen, trennen Sie unbedingt den Massepol der Autobatterie ab, um
Kurzschlüsse und Stromschläge zu vermeiden.
WÄHLEN SIE EINEN GEEIGNETEN EINBAUORT. Suchen Sie einen geeigneten Einbauort für das Gerät, bei
dem ausreichend Raum für eine kühlende Luftzirkulation vorherrscht. Am besten geeignet sind Reserverad-
mulden und offene Bereiche im Kofferraum. Weniger geeignet sind Stauräume hinter der Seitenverkleidung
oder Bereiche unter den Fahrzeugsitzen.
DAS GERÄT NICHT AN STELLEN EINBAUEN, AN DENEN ES HOHER FEUCHTIGKEIT ODER STAUB
AUSGESETZT IST. Bauen Sie das Gerät so ein, dass es vor hoher Feuchtigkeit und Staub geschützt ist. Wenn
Feuchtigkeit oder Staub in das Gerät gelangen, kann es zu Betriebsstörungen kommen. Schäden am Gerät,
welche durch Feuchtigkeit hervorgerufen wurden, unter- liegen nicht der Garantie.
DAS GERÄT SOWIE ANDERE KOMPONENTEN DES SOUNDSYSTEMS AUSREICHEND BEFESTIGEN.
Andernfalls könnten sich die Geräte und Komponenten während der Fahrt lösen und als gefährliche Geschos-
se im Fahrgastraum Beschädigungen und Verletzungen hervorrufen.
