A Note on Power Handling
JBL Decade Series speakers are
designed to produce reasonable volume
levels with little amplifier power.
However, the addition of a subwoofer
and an amplifier will enhance the
dynamic range of your system and help
overcome the ambient noise in a mov-
ing vehicle. These speakers are designed
to handle the power of a dedicated
amplifier driven at or below its rated
power. If an amplifier is driven far above
its rated power, the output signal will
“clip,” and the additional power present
in a clipped signal can damage the
speakers. Distorted or “fuzzy” sound
from your speakers is an indication that
the amplifier has exceeded its rated
power and you should reduce the
volume level.
General Care
The loudspeaker grilles may be cleaned
with a slightly damp cloth. Do not use
any cleaners or solvents on the grilles or
the speaker cones.
