Now, that said, using a 12V-5V charging adapter in place of an inverter probably makes a bit more sense, but in terms of needing to tuck all the electronics somewhere, it's probably whatever if you're in the trunk anyway.
What about just wiring 12v to this buck converter and step down to the 3.3V and wire to the AEX. I would use a relay for the 12V with the remote on from technics harness or from the amps remote.

Here is the stepdown powersupply to get from 12V to 3.3, no need to mess with usb 5v power.

Thinking that putting the AEX in the trunk and running optical into an alpine pxa-h800 would be a nice set up.
