Safety notes
Please observe the following safety notes during
the installation and connection.
–
Disconnect the negative terminal of the battery before
carrying out installation and connection work.
–
Observe the vehicle manufacturer's safety instructions
(regarding airbags, alarm systems, trip computers,
vehicle immobilisers).
–
Prior to drilling the mounting holes, make sure that no
cables and parts of the vehicle will be damaged.
–
Do not install subwoofers on loose rear shelves (fastback
vehicles) or at places open to the front.
–
Leave ample clearance between the cables and other har-
nesses. Use cable glands for holes with sharp edges.
Notes about installing subwoofer housings
Before installing the housing, please observe some funda-
mental design instructions:
Subwoofers with infi nite baffl e can be installed in a vehicle
by simply using a wooden board trimmed to size which
ensures an acoustic separation between the front and rear
sound components of a woofer. The wooden board is af-
fi xed in the boot under the rear shelf or in the back of the
rear seat bench. Any existing air gaps should be sealed with
sealing material.
The shape of the housing plays only a minor role with
respect to the playback of low frequencies and, therefore,
is rather freely selectable. However, try to avoid unusual
shapes which require extensive work with respect to trim-
ming and gluing.
MDF boards or high-quality plywood made out of birch
with a thickness of 18 to 25 mm are perfectly suited for
building speakers.
All abutting housing walls should be glued, screwed together
and sealed to avoid a continuing detachment due to vibra-
tions and environmental infl uences in the vehicle.
To avoid vibrations, stiff ening ribs are useful for large speak-
ers.

Acoustic insulating material (sheep's wool or polyester web)
which fi lls the inside volume to at least 50 percent increases
the eff ective housing volume by 5 to 15 percent.
The cables from the amplifi er to the subwoofer should be
kept as short as possible and have a cross section of at least
2.5 mm
2
.
The fi nished subwoofer housing should be perfectly stable
and airtight.
If possible, use bass reflex channels with a diameter of
7 to 10 cm to avoid the air noises generally associated with
smaller openings. PVC pipes are available commercially in
diff erent diameters, whereby the pipe sections can be routed
inside the housing using appropriate joints and fi ttings.
Use active (electronic) crossovers, such as those integrated
into all Blaupunkt amplifi ers. The use of passive crossovers
is not recommended.
