AMPLIFIER
DESCRIPTION
The optional Infinity premium speaker system includes a separate Infinity audio power amplifier. The amplifier is an
eight-channel unit rated at 368 total output watts. The amplifier is located behind the glove box. If equipped, an
additional amplifier rated at 140 watts is located under the center passenger seat.
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 section 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 six separate channels with dedicated feed and return circuits to the individual speakers.
