Circuit / System Description
Each of the audio output channel circuits (+) and (-), at the radio and audio amplifier have a DC bias voltage that is one half of the battery voltage. When using a DMM, each of the audio output channel circuits will measure approximately 6.5V?DC. The audio being played on the system is produced by a varying AC voltage that is centered around the DC bias voltage on the same circuit. The AC voltage is what causes the speaker cone to move and produce sound. This voltage will vary depending on what type of audio is being listened to, talk or music, and type of music, as well as the volume setting of the system. Low volume and talk settings will measure around 1V?AC and less, where constant music may measure 3V?AC and slightly higher. The amplifier may only supplied an amplified signal to the subwoofers, or on the premium audio systems, the amplifier will amplify all of the audio signals. The amplifier can not set DTCs.
