Installation Warnings and Tips
• Be careful not to cut or drill into fuel
tanks, fuel lines, brake or hydraulic lines,
vacuum lines or electrical wiring when
working on your vehicle. Inspect behind
panels before you cut or drill.
• Make sure that the midwoofer will phys-
ically fit in the mounting location. If door
mounting, check for adequate clearance
with the window in both rolled-up and
rolled-down positions as well as for inter-
ference with window crank and power
window mechanism. If mounting else-
where, check for clearance around rear
tanks, fuel lines, brake or hydraulic lines,
vacuum lines or electrical wiring when
working on your vehicle. Inspect behind
panels before you cut or drill.

A Note on Power Handling
As a result of their high effi-ciency, all JBL
loudspeakers will produce reasonable vol-
ume levels in the automotive environment
using very little amplifier power. However,
the use of a small amplifier to attain very
high volume levels could lead to over-dri-
ving the amplifier. This will generate high
distortion levels which can easily damage
loudspeakers, even if the rated power of
the amplifier is below the rated maximum
power handling of the loudspeaker!
As a general rule, do not turn up the vol-
ume control past the point where you
hear distortion in the form of either signal
distortion from an overdriven amplifier or
mechanical noise from an overstressed
speaker.
For the best performance and system reli-
ability, you should select an amplifier with
an output rating greater than the maxi-
mum power likely to be used to generate
the desired volume levels.
If you want your system “Loud + Clear,”
we suggest that you step up to a JBL
power amplifier which has an RMS power
rating equal to, but not exceeding the
Maximum Recommended Amplifier
Power listed in the specifications of your
specific JBL speaker. This margin of
reserve power will ensure that the amplifi-
er will not attempt to deliver more power
than its design allows. Your dealer will be
happy to point out which high power JBL
amplifiers are optimum for your applica-
tion and listening habits.
Following these guidelines will provide
virtually distortion-free sound reproduc-
tion and long loudspeaker life.

• Do not mount speakers where water may
splash on the cones.
• Make sure that it will be easy to run con-
necting wires to the speakers. Trace speak-
er wire paths before you undertake
mounting.
• Always disconnect the ground wire from
the battery before doing any work on the
vehicle.

WARNING: Playing loud music over
120dB can permanently damage your
hearing. The maximum volume levels
achievable with JBL components and
high power amplification may exceed
safe levels for extended listening. When
listening at high volume levels, always
use hearing protection or turn it down!
