information on its correct operation.
• For safety reasons, any unauthorised conversion and/or modifi cation to the product is not permitted.
• Do not expose the subwoofer to high temperatures, drips or water spray, strong vibrations or heavy
mechanical stress.
• Never pour liquids over electrical devices and never place objects fi lled with liquid on top of them.
• Do not place naked fl ames such as burning candles on top of the device.
• When connecting the subwoofer, consult the safety instructions of the device to which it is to be connected.
• Do not place any magnetic storage media such as fl oppy disks or video cassettes close to the car louds-
peakers, as the subwoofer's magnetic fi eld may corrupt data stored on such storage media.
• Do not listen to excessively loud music for long periods of time. This may damage your hearing.
• Excessive volume inside a car may result in you not hearing acoustic warning signals. This constitutes a
danger to yourself and to other road users. Therefore, ensure the volume is at a suitable level.
• Lack of attention in traffi c can lead to serious accidents. Therefore, only use the hi-fi system when the
traffi c situation permits and you will not be unduly distracted by operating the system.

Product Description
• Powerful 200 mm Subwoofer
• Bass refl ex cabinet for clear, deep bass reproduction
• Stable clamp to protect the loudspeaker diaphragm
Installation
Modifi cations to the vehicle, which are made necessary due to the installation of the
subwoofer, must always be carried out in such a manner that neither the traffi c safety nor
the designed stability of the car is impaired. With many vehicles, the MOT will be void, if
you cut out a section of the sheet metal.
If you are in doubt about where to install the device, consult your car dealer.
Before drilling, make sure that this will not damage any electric cables, brake leads, the
fuel tank or suchlike.
When using tools to install your car's hi-fi components, follow the manufacturer's safety
instructions.
When installing the subwoofer or your hi-fi system, please take into account the risk of
injury that can arise from devices being torn away in the event of an accident. Therefore,
you should secure each component in a place where it cannot pose a risk to passengers.
• Select a place suitable for installing the subwoofer. The boot is a suitable place for installation.
• Fasten the subwoofer with belts, clamps or similar, suitable mounting material. A secure attachment in the
spare wheel recess also might be possible.

In order to ensure clear playback, you must operate the subwoofer via an amplifi er with an active switch,
which ensures:
• that there is suffi cient output
• that the subwoofer is only supplied with the bottom bass range of the music signals
• Depending on the vehicle, set the crossover frequency for the active switch between 100 and 150 Hz.
Connect the subwoofer's loudspeaker lead to the loudspeaker connection terminal on the subwoofer amplifi er:
- red terminal, or the terminal labelled with
- black terminal or the terminal labelled with
Maintenance and Care

Before reconnecting the negative terminal to the battery, ensure that the device has been
completely connected.
Only use a volt meter, or a diode test lamp, to check the voltage of the vehicle sys-
tem leads, as normal test lamps consume excessive voltage and may thus damage the
vehicle's electronics.
When connecting the subwoofer, make sure that the connection cables are not pinched
or damaged by sharp edges.
Only connect to suitable loudspeaker outputs from a car amplifi er.
Make sure the impedance and power rating indicated in the technical data complies with
