Audio output and gps power

[bruce747jodel]

I am running all the audio inputs from nav and com through an AP60 mixer. Does it make any difference if I use the left or right output from the skyview, or do I need to use both?
Also, I am fitting three screens in my 8. I realise that the gps signal wires have to connect to each display but do I have to connect the power supply from each screen to the gps aswell, if so I assume the three positve and three negative wires can be bundled together?

Tie the audio inputs together if you have a mono input.

Connect the power and ground lines from all the GPSes to all of the screens in parallel.
