Placement and Warnings
Your JBL speakers are designed
for the rigors of the automotive
environment and can withstand
high and low temperatures as
well as extreme humidity.
However, you can effectively
increase the life of your speakers
by avoiding installations that
expose them directly to moisture
or water. For safety and reliabil-
ity, they should be securely fas-
tened to prevent them from mov-
ing around when driving, or from
becoming dangerous missiles in
the event of an accident or sud-
den stop.
Select your mounting locations
very carefully so as to avoid cut-
ting or drilling into critical com-
ponents such as brake or fuel
lines, and electrical wiring,
which may be damaged when
drilling holes for the mounting
screws. Be especially cautious
because these components may
be hidden between double-walled
panels.
General Installation Guidelines
03
The mounting locations for opti-
mum performance will vary from
vehicle to vehicle, but in general
your Powered Subwoofer will
work well just about anywhere:
In the trunk, hatch area, or any
surface large enough to accom-
modate it. Just make sure to
keep at least 3" clearance around
the port end of the unit so that
you do not restrict port airflow.
Unlike some other brands, your
JBL subwoofer does not require
corner loading for optimum per-
formance, which means that it
may be pointed whichever way is
most convenient for your particu-
lar installation. Pointing the unit
into a corner will increase its low
frequency output, which will
please some listeners. Others
might find this increase too
much, and will prefer pointing
the unit away from the corner.
Since each vehicle model has dif-
ferent acoustic characteristics,
we recommend experimentation
with placement before perma-
nently mounting your subwoofer.
Also, leave space around the
amplifier end of the unit so that
airflow is not restricted, other-
wise the unit may overheat and
activate its protection circuitry.
