Connection
To avoid short circuits and any resulting damage, the negative terminal (earth) of the car
battery must
fi
rst be disconnected.
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.
The loudspeakers may only be connected to suitable loudspeaker outputs on a car-
ampli
fi
er.
Make sure the impedance and power rating indicated in the technical data complies with
the data for the ampli
fi
er connected. Otherwise, damage to the subwoofer or the ampli
fi
er
can occur.
In order to ensure clear playback, you must operate the subwoofer via an ampli
fi
er with an active switch,
which ensures:
• that there is suf
fi
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 to between 80 and 120 Hz.

chanical 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 subwoofer,
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.

fi
c can lead to serious accidents. Therefore, only use the hi-
fi

Product Description
The car subwoofer has the following features:
• Bass-re
fl
ex principle
• 30 cm (12“)-subwoofer chassis
• Sturdy felt cover
• 2 sturdy loudspeaker protection bars
Installation
Modi
fi
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 traf
fi
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 lead to any damage to electric cables, brake
leads, the fuel tank or similar.
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.
• Attach the speaker casing with straps or similar
fi
x ings. The
fi
xing must also be able to support the load of
the speaker in case of an emergency stop or an accident.
• The boot is a suitable place for installation.
