https://github.com/dtcooper/raspotify Use raspotify on the PI directly, it turns it into a Spotify Connect target. I use that on my PI that runs alot of other crap that is headless. For the amplifier I'd rather get a cheap auto head-unit that has an Aux-in, as those are made to run on 12V directly and are, well, cheap.
