RAM 1500 Van V8-5.2L CNG VIN T (1999)
Amplifier: Description and Operation
DESCRIPTION
Models equipped with the Infinity premium speaker package have a separate power amplifier unit. This power amplifier is rated at 120 watts
output. The power amplifier unit is mounted to the inboard side of the right instrument panel end bracket, outboard of the glove box opening under
the passenger side end of the instrument panel. The power amplifier unit can be accessed for service through the glove box opening by rolling the
glove box down from the instrument panel.
The power amplifier unit should be checked if there is no sound output noted from the speakers. For diagnosis of the power amplifier, refer to
Speaker in the Diagnosis and Testing. The power amplifier cannot be repaired or adjusted and, if faulty or damaged, the unit must be replaced.
OPERATION
The power amplifier is energized by a fused 12 volt output from the radio receiver whenever the radio is turned on. The power amplifier receives
the sound signal inputs for four speaker channels from the radio receiver, then sends the amplified speaker outputs for each of those channels
through separate circuits to the six individual speakers.
