AMPLIFIER
DESCRIPTION
The amplifier (2) is available in two ratings: 288 watt
(RD7), and 380 watt (RDF). The amplifier is mounted
to the left of the steering column under the instrument
panel.
OPERATION
The amplifier receives fused battery current from a fuse in the rear Power Distribution Center (PDC) at all times.
The internal circuitry of the amplifier switches the amplifier ON based upon a CAN bus message that is received
from the radio receiver whenever the radio is turned on. The amplifier receives the sound signal inputs from the left
and right rear outputs of the radio, then sends the amplified speaker outputs for each of those channels to the
speakers.
