PROBLEM
CAUSES AND SOLUTIONS
Sound only comes from some of
the speakers connected to the
amplifier:
the speakers connected to the
amplifier:
• Check that the settings of the amplifier’s Input Routing switches match the
input and speaker connections made to the amplifier.
• Check that the vehicle audio system’s source unit’s balance and fader controls
are set to their center (midpoint) positions.
• If the subwoofer is silent and the optional Remote Bass Control is
connected to the amplifier, check that it is not turned all the way down (fully
counterclockwise).
counterclockwise).
Sound is too quiet, even with the
vehicle audio system’s head unit
volume turned all the way up:
vehicle audio system’s head unit
volume turned all the way up:
• Check the amplifier’s Input Level switches. If they are set to “Hi1,” turn the
amplifier’s Gain controls all the way down and re-set the Input Level switches
to “Low.” Then perform the Set the Gain procedure, on page 9, again.
