This symbol adverts you a important reference note on the following pages. Attend these reference notes by any means, otherwise damage of the device or the vehicle may be caused. Furthermore serious injuries may be caused by not following these reference notes.

REFERENCE NOTE!
VERY IMPORTANT ADVICE FOR THE INSTALLATION AND OPERATION IN NEWER VEHICLES!
In vehicles with a newer year of manufacturing (since approx. 2002), normally computer controlled diagnosis- and controlling systems are applied - like CAN-BUS or MOST-BUS interfaces. By the installation of a car audio amplifier a new appliance will be added to the 12V on-board electrical system, which may cause under several circumstances error messages or may interrupt this factory made diagnosis system, as a result of high stress peaks and a higher power consumption. Thus to this, depending on model and manufacturer, the driving safety or important security systems like airbags, ESC or others could be interrupted.
If you plan to operate the amplifier in a vehicle like described above, please follow these instructions:
- Admit the installation only by a skilled specialist, best by a service company, which is specialized on maintenance and repairing your vehicle and which is familiar with the electrical on-board system of the vehicle.
- After the installation, order by any means a computer based diagnosis of the on-board system by your service company to detect possible malfunctions or error messages.
- If the on-board system is interrupted by the installation of the amplifier, in-between installed power capacitors can stabilize the electrical on-board system and ensure a proper and stable operation.
- The best solution is the integration of an additional second 12V electrical system for the complete sound system, which can be operated independently via a own battery supply.
CONSULT BY ANY MEANS YOUR CAR SPECIALIZED SERVICE COMPANY!
PLEASE KEEP THIS MANUAL FOR LATER PURPOSES!
PLEASE ATTEND THE FOLLOWING ADVICES BEFORE THE FIRST OPERATION!
THE PURCHASED DEVICE IS ONLY SUITABLE FOR AN OPERATION WITH A 12V ON-BOARD ELECTRICAL SYSTEM OF A VEHICLE. Otherwise fire hazard, risk of injury and electric shock consists.
PLEASE DO NOT MAKE ANY OPERATION OF THE SOUND-SYSTEM, WHICH DISTRACT YOU FROM A SAFE DRIVING. Do not make any procedures, which demand a longer attention. Perform these operations not until you have stopped the vehicle on a safe place. Otherwise the risk of accident consists.
ADJUST THE SOUND VOLUME TO AN APPROPRIATE LEVEL, THAT YOU ARE STILL ABLE TO HEAR EXTERIOR NOISES WHILE DRIVING. High performance sound systems in vehicles may generate the acoustic pressure of a live concert. The permanent listening to extrem loud music may cause the loss of your hearing abilities. The hearing of extreme loud music while driving may derogate your cognition of warning signals in the traffic. In the interests of the common safeness, we suggest to drive with a lower sound volume. Otherwise the risk of accident consists.
DO NOT COVER COOLING VENTS AND HEATSINKS. Otherwise this may cause heat accumulation in the device and fire hazard consists.
DO NOT OPEN THE DEVICE. Otherwise fire hazard, risk of injury and electric shock consists. Also this may cause a loss of the warranty.
REPLACE FUSES ONLY WITH FUSE WITH THE SAME RATING. Otherwise fire hazard and risk of electric shock consists.
DO NOT USE THE DEVICE ANY LONGER, IF A MALFUNCTION, WHICH REMAINS UNREMEDIED. Attend in this case the chapter TROUBLE SHOOTING. Otherwise risk of injury and the damage of the device consists. Commit the device to an authorized retailer.
THE INSTALLATION OF A POWER CAPACITOR WITH SUFFICIENT CAPACITY IS RECOMMENDED. High performance amplifiers cause high potential voltage drops and need a high power consumption at a high volume level. To relieve the vehicle's on-board system, it is recommended to install a power capacitor between the battery and the device which works as buffer. Consult your car audio retailer for the appropriate capacity.
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 safness, commit the interconnexion 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 A APPROPRIATE LOCATION FOR THE INSTALLATION OF THE DEVICE. Look for a 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.
ATTEND 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.
ENSURE CORRECT CONNECTION OF ALL TERMINALS. Faulty connections may could cause fire hazard and lead to damages of the device.
DO NOT INSTALL AUDIO CABLES AND POWER SUPPLY WIRES TOGETHER. Attend while installation not to lead the audio cables between the headunit and the amplifier 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 security-relevant 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 bended 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, a risk of serious injuries consists. Consult promptly a medical doctor, if a child swallowed a small object.

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.
MECHANICAL INSTALLATION
Avoid any damage removing of the components of the vehicle like wires, cables, board computer, seat belts, gastank or the like.
Ensure that chosen location provide sufficient air circulation for the amplifier. 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 amplifier on top of a subwooferbox or any other vibrating parts, thereby parts in the inside of the amplifier may get loosen.
The wires and cables of power supply and the audio signal must be as short as possible, to avoid any losses and interferences.

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 25 mm ^2 ), 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, insufficient power supply or interferences.

FUSE
The inserted fuses protect the amplifier from shorts and capacity overload. The equipped standard fuse is suitable for a 4 ohm speaker load. For a 2 ohm speaker load the current consumption increases by 50%, thereby the fuses may need to be replaced by fuses with a higher rating.

BATT+12V
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. 25 mm ^4 ) and install a 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.

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.

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. Use a ground wire with a sufficient cross section (at least 25 mm ^2 ) and the same size like the plus (+12V) power supply wire.

REFERENCE NOTE
Installation of RCA/Audio signal cables and power supply.
Attend while installation not to lead the audio cables between the headunit and the amplifier 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.

REFERENCE NOTE
PROTECTION CIRCUIT
This amplifier owns a 3-way protection circuit. If overloading, overheating and shorted loudspeakers, or too low impedance or insufficient power supply is insisted, the amplifier shuts down to prevent serious damage. If one of this disfunctions is detected, the red PROTECT LED lights up.
Check in this case all connections to detect short-circuits, faulty connections or overheating. Attend the regarding notes on the previous page.
If the reason for the disfunction is eliminated, the amplifier is ready for operation again.
If the red PROTECT LED does not stop to light up, a damage on the amplifier is insisted. In this case return the amplifier to your car audio retailer with a detailed malfunction description and a copy of the proof of purchase.
WARNING: Never open the amplifier and try to repair it by yourself. This causes a loss of warranty. The repairing service should be made only by skilled technicians.

REFERENCE NOTE
ELECTRICAL INTERFERENCES
The reason for interferences are mostly the passed cables and wires. Especially the power and audio cables (RCA) of your sound system are vulnerable. Often these interferences are caused by electric generators or other electrical units (fuel pump, AC etc.) of the car. The most of these problems can be prevented by a correct and careful wiring.
Here are some courtesy notes:
- Use only double or triple shielded audio RCA cables for the connection between the amplifier and headunit. A useful alternative are represented by anti-noise-devices or additional ancillary equipment like Balanced Line Transmitters, which you can purchase at your car audio retailer. If possible do not use anti-noise-filters, which are splicing the ground of the RCA audio cables.
- Do not lead the audio cables between the headunit and the amplifier 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.
- Avoid ground loops by connecting all ground connections in a starlike arrangement. The suitable ground center point is ascertainable by measuring of the voltage directly on the vehicle's battery by a multi-meter. You should measure the voltage with turned-on inginition (acc.) and with other turned-on power consumers (e.g. headlights, rear window defroster, etc.). Compare the measured value with the voltage of the ground point you have chosen for the installation and the positive pole (+12V) of the amplifier. If the voltage has just a little difference, you have found a suitable ground point. Otherwise you need to choose another ground point.
- Use if possible only cables with added or soldered cable sockets or the like. Gold plated or high value nickel plated cable sockets are corrosionfree and own a very low contact resistance.
