•  Positioned under the trunk side trim (LH).

•  Converts music signals (analog voltage waveform) from the audio unit to digital signals, then amplifies and outputs them.
•  The 2-channel (left and right) audio signals are converted to simulated 5-channel in the audio amplifier and output to each speaker. Due to this, surround sound can be enjoyed with the source from a 2-channel recorded CD.
