Analog Amplifier for Pine64

I would like to make an car amplifier extension board. Can anyone suggest me about the following topics:

- Volume adjustment (volume can be adjusted over I2C, what is the best way, adjusting volume of analog output of pine64 or tas524C)
- Audio input, there are four channels, pine64 has only 2 ch output. How can I do it?
- Fault, Mute, standby, clip_otw, is it necessary to use these pins with Pine?
(typical application circuit attached)
