Nice post Zoidiano0!
First thing first, I would focus on powering up the unit via Car electronics. My understanding is that you need 12V from the battery line, 12V from the accessory line and the ground. 12V would need to be stepped down to 3.3 or 5V for Pine (believe these two lines are available on both bus connectors).
Also, may want to have the audio amplifier (4x50W) power up by 12V battery. One of these suckers will also need a heatsink.
So, it would make sense to me to have power (step down), and audio amp on the same board (shield for the Pine64).
