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 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 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.

Fastening

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 and 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.

+12V

Connect the 12 volt terminals of the amplifier to the positive poles of the power capacitors by using suitable cables. Then connect the positive poles of the power capacitors to the 12 volt positive pole of the additional battery.
_ _ATTENTION:__ Use for both connections sufficiently dimensioned cables of at least Ø 50 mm2 with a total length of max. 1,5 meters. If you use longer cables, the cross-section must be correspond- ingly larger. Use very short cable lengths from the amplifier to the power capacitors, which should be mounted close as possible to the amplifier.

REM

Connect the turn-on signal from your head unit / car radio (REM) with the REM terminals of the power capacitors. Then connect the REM terminal of one of the power capacitors with the REM terminal of the amplifier. Hereby the amplifier and the power capacitors are turning on or off with the head unit / car radio. Use therefor suitable cables with a sufficient cross section (0,5 mm2).

GND

Connect the minus poles of the power capacitors with a suitable contact ground point on the vehicle’s chassis. Then connect the minus poles of the power capacitors with the GND terminal of the amplifier. The ground wires 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 the ground wires from the battery to the ground point if possible and enforce it if required.

_ _ATTENTION:__ Use for both connections sufficiently dimensioned cables of at least Ø 50 mm2 with a total length of max. 1,5 meters. If you use a longer cable, the cross-section must be correspond- ingly larger. Use a very short cable length from the amplifier to the power capacitor, which should be mounted close as possible to the amplifier.

FUSES (NOT INCLUDED)

The amplifier inherently has no internal device fuses. You should therefore use suitable fuses and holders from a specialist retailer and install them in the power cables near the 12 volt terminal of the amplifier. The distance between the fuses and the amplifier should not exceed 15 cm. Please note the recommendations for the fuse values on page 16.

ADDITIONAL CABLE FUSE (NOT INCLUDED)

Install an extra fuse (not included) for the +12V power cable near the battery to secure the power cable. The distance between the fuse and the battery should not exceed 30 cm. The fuse size must be adapted to the cable cross- section of the installed power cable.

_ _ATTENTION:__ The fuse at the battery does not protect the amplifier, but the cable between the battery and the amplifier against short circuits.

POWER CAPACITORS (NOT INCLUDED)

We generally recommend operating this amplifier with suitable power capacitors (powercaps), which are not included in the scope of delivery. A power capacitor offers a more constant power supply, a sound improvement and better bass performance of the amplifier. The higher the nominal capacity, the better it absorbs unpleasant voltage fluctuations and stabilizes the entire sound system. For maximum benefit from the power capacitor, mount it as close to the amplifier as possible.
With an output power per 1000 watts RMS, we recommend a capacity of 1 farad. Further information is available from specialist retailers.
For the connection and operation, please also refer to the instructions for the power capacitor.

DESCRIPTION OF OPERATION

TROUBLE SHOOTING

NO FUNCTION / THE POWER LED IS NOT ILLUMINATED

First check the fuse of the routed power cable on the additional battery
The fuse is defective

Replace the defective fuse with an equivalent one, never with a higher value.

•   The fuse fails again.

In this case there appears to be a short circuit between the fuse and the amplifier. To do this, check the + 12V power cable along its entire length from the battery to the amplifier for damage and whether there is a short circuit to ground, e.g. a contact with the vehicle chassis or the body. If necessary, replace the defective power cable.

The fuse is apparently okay

Use a standard 12 volt voltmeter to check the voltage between the + 12V connection and the ground connection on the amplifier.

•   There is no voltage.

Use the voltmeter to check the fuse, which is located close to the additional battery, to see whether there is voltage between the output and ground.

If there is no voltage there, either the fuse holder or the fuse is defective, although it appears to be okay. If necessary, replace the fuse holder or fuse.

•   There is voltage.

If you operate the amplifier with a pre-amplifier signal (RCA), you must have laid a remote turn-on wire from the head unit to the REM terminal of the amplifier.

A remote turn-on wire is connected to the REM terminal at the amplifier.

Use the voltmeter to check whether there is voltage between the REM terminal of the amplifier and ground. The head unit must be switched on.

There is no voltage.

•   Check the remote turn-on wire from the amplifier to the head unit for a short circuit or damage. If necessary, replace the control line..

There is voltage.

•   The amplifier is probably malfunctioning or defective. Contact your retailer.

THE POWER LED IS ON, BUT NO SOUND COMES FROM THE SPEAKERS

Check the following steps:
Low level mode: Are the RCA cables on the head unit and on the amplifier correctly connected?

•   The RCA cables are correctly connected.

Then an RCA cables could be defective. Check the function of the RCA cables on another audio device. If necessary, replace the defective RCA cables.

Are the speaker cables correctly connected between the speakers or the subwoofer at the speaker outputs of the amplifier?

•   The speaker cables are connected correctly.

A speaker cable could be defective. If necessary, replace the speaker cable or insulate the damaged area.

Is the high pass filter or subsonic filter set higher than the low pass filter on the amplifier?

Then slowly turn down the controller for the high pass filter or subsonic filter until the sound can be heard.

Is the input mode switch on the amplifier set correctly?

Check the setting and change the switch position if necessary.

Are the crossover switches on the amplifier set correctly?

Check the settings and change the respective switch position if necessary.

Are the speakers or the subwoofer working?

Hold a standard 9 volt block battery to the terminals of each loudspeaker or the subwoofer.

•   A faint cracking sound can be heard. The speaker or subwoofer is fine.

•   There is nothing to be heard.

The loudspeaker or subwoofer could be defective. If necessary, replace the defective speaker or subwoofer.

Are the settings on the head unit set correctly?

•   Check the fader and balance settings

•   Check whether the mute function is activated

•   Check whether a high pass or low pass filter is activated

•   Check whether playback has been paused

•   Check the source settings

•   Check whether any existing subwoofer output is activated

TROUBLE SHOOTING

DISTORTION OR HISSING NOISE CAN BE HEARD FROM THE SPEAKERS

Check the following steps:
Is a input level controller on the amplifier set too high?

Slowly turn the controller back until you hear a clean audio signal.

Is the Bass Boost controller on the amplifier set too high?

Slowly turn the controller back until you hear a clean audio signal.

Is the loudness function on the head unit set too high?

Deactivate loudness or turn the loudness setting back until you can hear a clean audio signal.

Are the EQ and sound settings on the head unit set too high?

Turn down the settings for Treble, Middle and Bass or deactivate the equalizer until you can hear a clean audio signal.

ENGINE SPEED DEPENDENT NOISE CAN BE HEARD FROM THE SPEAKERS

Check the following steps:
Have the RCA cables been laid separately from the power cable in the vehicle?

If necessary, lay the cables again and make sure that the audio cables are laid separately from the power cable on the left and right in the vehicle.

Is the amplifier’s ground connection correctly connected?

Make sure that the ground connection of the amplifier is not connected directly to the negative pole of the additional battery. Select a suitable ground point on the vehicle body for connection. If necessary, use contact spray to improve the conductivity of the connections.

Is the conductivity of the ground cable from the additional battery to the body okay?

Make sure that the ground connection of the additional battery has a stable and conductive connection to the body. If necessary, use contact spray to improve the conductivity of the connections.

AN ACTIVE OPERATED TWEETER IS DISTORTED OR CRACKED

CAUTION: Tweeters will be damaged if the frequencies are too low. Please note the manufacturer’s information on which frequency setting is recommended. To be on the safe side, pause the play- back of the head unit first. Check the following steps:
Is the crossover mode switch of the relevant channel pair on the amplifier set correctly?

Set the crossover mode switch to the high pass position (HP or HPF).

Is the high pass filter of the relevant channel pair set too low on the amplifier?

First turn the high pass controller fully clockwise. Now start playback on the head unit. Then turn the high pass controller slowly counter-clockwise until you can hear a clean sound from the tweeters and produce a balanced sound together with the woofers/mid-range speakers. Make sure that the woofers/ mid- range speakers are set correctly with the respective high pass and low pass controllers.

AMPLIFIER ACTIVATES THE PROTECTIVE CIRCUIT / THE PROTECT LED LIGHTS UP

Check the following steps:
Short circuit on the speaker cables

•   First disconnect all speaker cables from the amplifier. Use a multimeter to check the ohmic impedance of each loudspeaker by measuring between its plus and minus lines. With standard loudspeakers the value fluctuates between 3 and 5 ohms. The values for low-resistance subwoofers can be lower.

•   The measurement shows a resistance value of less than 0.5 Ohms

Then there is a short circuit. Remove the wiring of the affected loudspeaker at its connections. Now use the multimeter to check the ohmic impedance directly at the loudspeaker connections by measur- ing between the plus and minus connections.

The measurement shows a resistance value of more than 0.5 Ohms

•   The speaker is fine, so the speaker wire appears to be defective and causing a short circuit. Replace the defective speaker cable.

The measurement shows a resistance value of less than 0.5 Ohms

•   The speaker appears to be defective and is shorting out. Replace the defective speaker.

The load impedance of the loudspeakers or the subwoofer is too low

•   Compare the ohmic impedance of the connected loudspeaker or subwoofer with the technical speci- fications of the amplifier. For example, if the amplifier is only designed for 2 or 4 ohm operation, no loudspeaker with less than 2 ohms may be connected.

The cross-section of the power cables is too small

•   If the cable cross-section is too small, this leads to an increased ohmic resistance and thus to a volt- age drop (voltage loss). This indicates that the amplifier consumes more power. The increased power consumption results in a significantly higher heat development and the amplifier switches to thermal protection mode. Therefore, observe the recommended cable cross-sections in these instructions and, if necessary, lay power cables with a larger cable cross-section.

The amplifier is overheated

•   The heat sink of each amplifier requires sufficient air circulation to be able to dissipate the heat gener- ated during operation. If necessary, change the installation position in favor of better cooling of the amplifier or ensure better air circulation at the installation location.

•   Turn off the sound system and wait about half an hour for the amplifier to cool down again. With very hot outside temperatures and strong sunlight, enormous heat develops inside the vehicle. The amplifier then activates its thermal protection circuit to prevent damage. After cooling down, the amplifier works properly again.
