Ako je moguće, koristite refleksne kanale za bas prečnika od 7 do 10 cm
kako biste izbegli šumove koje stvara vazduh na malim otvorima.
PVC cevi se mogu kupiti u različitim prečnicima, pri čemu se delovi
cevi mogu sprovesti unutar kućišta pomoću odgovarajućih zglobova

Safety notes
installation and installation instructions
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 harnesses. Use
the enclosed cable ducts at sharp-edged holes.

notes about installing subwoofer housings
Before installing the housing, please observe some fundamental design
instructions:
Subwoofers with infinite baffle 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 affixed in the trunk 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 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 detachment due to vibrations and envi-
ronmental influences 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 0 percent increases the effective
housing volume by  to 1 percent.
The cables from the amplifier to the subwoofer should be kept as short
as possible and have a cross-section of at least 2.5 mm
The finished subwoofer housing should be perfectly stable and air-
tight.
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 different diameters, whereby
the pipe sections can be routed inside the housing using appropriate
joints and fittings.
Use active (electronic) crossovers, such as those integrated into all Blau-
punkt amplifiers. The use of passive crossovers is not recommended.
Recycling and disposal
