DEAR CUSTOMER,
We congratulate you on acquiring this MAGNAT
Car Stereo Product.
Please read these instructions carefully
so as to ensure optimum and disturbance-
free functioning of the appliance. Technical
modifications reserved.
POSITIONING AND SECURING THE
SUBWOOFER
IMPORTANT: Please ensure when fitting
illuminated components that for purposes
of traffic safety while driving no light shines
outside the vehicle which could have an
adverse effect on other road-users.
Ensure that the subwoofer cabinet rests on an
even surface. The cones (and, where applicable,
the bass reflex tube) should not be placed directly
against the car’s interior walls.
Make sure that the subwoofer is secured in
such a way that it cannot slip or slide. Damage
resulting from sudden changes in speed (e.g.
hard braking) is not covered under the terms
of our guarantee.
CONNECTING TO THE POWER AMPLIFIER
(FIG. 1)
The subwoofer should be connected to an external
power amplifier in every case. This can provide the
required electrical power and create corresponding
dynamic reserves. The relevant instructions also
contain the customized connection diagram for the
operation of a subwoofer.
CONNECTING THE ILLUMINATION (FIGURE 1)
Important, please read carefully.
Connect the +12 v terminal to the +12 v electrical
circuit in your car. The +12 v terminal of the
subwoofer light (fig. 1, right screw terminal)
must be connected to the positive cable on the
vehicle‘s electrical wiring system via a cable fuse
(500 mA slow-blow, precise specification: T500mAL
250 volt, fuse and fuse holder not supplied).
Now connect the car hi-fi receiver‘s remote control
connection to the amplifier‘s REM control jack
on the terminal (Fig. 1, middle terminal screw). A
cable with a cross-section of 0.75 mm² is sufficient
for connecting the amplifier‘s REMOTE connection
to the control device.
The maximum power value that can be output by
the remote control line must be observed. If this
is not sufficient, an electronic relay connection
must be added.It is therefore advisable to have
the installation carried out by a qualified auto-
electrician, especially if you are not familiar with
the electrical wiring system on your vehicle.
The negative terminal of the subwoofer light
(Fig. 1, left terminal screw) must be connected
conductively to the vehicle chassis.
Fuse, fuse holder (cable fuse), relay connection
and switch are available from specialist dealers.
N.B.!
On no account may the light remain permanently
connected to the battery, as the battery will
otherwise discharge within a few days. When using
a separate switch connected to the battery, the
light must be switched off when leaving the vehicle.
CABLES TO BE USED
To transport the output from the amplifier to the
subwoofer efficiently and reliably, you should bear
in mind when selecting the speaker cable that 2 x
4 mm ² gauge wiring is required for cable lengths in
excess of 3 meters. 2 x 2.5 mm² cable is sufficient
for shorter runs. Lay the cable in such a way that
short-circuiting cannot occur, i.e. the cable may
at no time be jammed between metal parts. Make
sure that terminals on the speaker are screwed
tight and check their contact at regular intervals.
SUBWOOFER POLARITY
Because of the different spatial conditions
prevailing in different vehicles, subwoofer polarity
can best be determined by trial and error. To do
this, choose some music material you know very
well and select the setting you like most. Some
radios / control units also offer the possibility of
setting the polarity on the appliance itself (phase).
One change in polarity corresponds to a phase
shift of 180 degrees.
