A Note on Power
Handling
As a result of their high effi-
ciency, all JBL loudspeakers will
produce reasonable volume levels
in the automotive environment
using very little amplifier power.
However, the use of a small
amplifier to attain very high vol-
ume levels could lead to over-
driving the amplifier. This will
generate high distortion levels
which can easily damage loud-
speakers, 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 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 over-
stressed speaker.
For the best performance and
system reliability, you should
select an amplifier with an output
rating greater than the maximum
power likely to be used to gener-
ate 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 amplifier 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 opti-
mum for your application and
listening habits.
Following these guidelines will
provide virtually distortion-free
sound reproduction and long loud-
speaker life.
WARNING: Playing loud music
over 120dB can permanently
damage your hearing. The maxi-
mum 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 protec-
tion or turn it down!
