Safety Notes
Installation and installation instruc-
tions
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 harnesses. Use the enclosed cable ducts
at sharp-edged holes.
Notes about installing subwoofer hous-
ings
Before installing the housing, please observe some
fundamental 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 be-
tween the front and rear sound components of a
woofer. The wooden board is affi 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 exten-
sive work with respect to trimming 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 detach-
ment due to vibrations and environmental infl u-
ences in the vehicle.
To avoid vibrations, stiffening ribs are useful for
large speakers.
Acoustic insulating material (sheep's wool or
polyester web) which fills the inside volume
to at least 50 percent increases the effective
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
The fi nished subwoofer housing should be per-
fectly stable and airtight.
If possible, use bass refl ex channels with a di-
ameter of 7 to 10 cm to avoid the air noises gen-
erally associated with smaller openings. PVC
pipes are available commercially in different di-
ameters, whereby the pipe sections can be rout-
ed 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.
