A Note on Power Handling
As a result of their high efficiency, all JBL
loudspeakers will produce reasonable
volume levels in the automotive environ-
ment using very little amplifier power.
However, the use of a small amplifier to
attain very high volume levels could lead
to overdriving the amplifier. This will gen-
erate high distortion levels that can easily
damage loudspeakers, even if the rated
power of the amplifier is below the rated
maximum power handling of the loud-
speaker!
As a general rule, do not turn up the
volume 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
maximum 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 ampli-
fier 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 optimal for your
application and listening habits.
Following these guidelines will provide
virtually distortion-free sound reproduc-
tion and long loudspeaker life.
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 the
volume down!
