A high hiss or
engine noise
(alternator
whine) is
audible in the
speakers
Disconnect all RCA inputs to the amplifier. If
the hiss or noise goes away, plug in the
component driving the amplifier and unplug its
inputs. If the noise goes away, start plugging
in the inputs until the noisy component is
found.
We recommend that you set the amplifier
input sensitivity as low as possible. This will
result in the best possible S/N ratio. Also, try
to drive as high a signal level as possible from
the head unit.
