So, I have in-ceiling speakers in my house. I've never used them. What I want to do is set myself up so that my Amazon Echo devices can be used to play music or podcasts or audiobooks through those speakers throughout my house.
So, Calgarypuck home theatre mavens... what do I do? Where do I start? I presume I need an amp, but what should I get so that it all hooks up to the Alexa/Echo system?
For reference, here is what I currently have: a bunch of wires coming out of the ceiling in my furnace room...
I'm assuming they all go to different speakers and at a glance none appear to be clearly labeled. Open to all suggestions...
