I cannot find anything for how the AMP2 links to the Pi - do you just route audio out from the 4 pole connector to audio in or does the Pi have to control the amp via software?

What LCD do you plan to use? Some have built in buttons, others have RGB backlighting only etc...

A link to the power supply would help as well please.
