Dodge Journey: Amplifier

DESCRIPTION

The optional premium speaker system includes a separate audio power amplifier. The amplifier is an eight channel unit. The amplifier is located behind the right cowl trim panel.

OPERATION

The power amplifier electronically increases the frequency response of the normal audio signal output from the radio amplifier in order to improve the acoustic performance of the speakers. On vehicles equipped with an amplifier, the amplifier information of the radio becomes a pre-amplifier.

The amplifier receives audio signal inputs for speaker channels from the radio, then sends amplified audio outputs through eight separate channels with dedicated feed and return circuits to the individual speakers.
