DEAR CUSTOMER,
We congratulate you on acquiring this MAC AUDIO
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 SUBWOOFERS
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
250volt, 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 mm² 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.
