Helix DSP: route two channel input to four channels out?

[supoaneko]

I'm stuck on this. I'm digging through the software but not finding it.

1) How can I take this two channel input I have (currently coming from phone until optical USB box comes for head unit) to output four channels? Right now I'm using y-splitters to accommodate this but there's gotta be a better way.

2) How do I switch to the AUX input? I tried changing my remote to enable AUX but it's not doing it. Heck, which input does the Helix consider AUX?
