@ speaker setup

Hi

I have what I believe is a very simple project that I can achieve with Arylic DYI products but need some help. I have a backyard setup that will have 2 speakers that I want divided into 2 zones/rooms so down the road i can add speakers inside my house. I want to play 2 speakers at one time outside, the other 2 at another time (or a separate audio source then the other 2 at the same time) or all 4 playing at the same time with a single audio source. Can anyone suggest the best option?

Thank you!

Hi and welcome to the forum.
I would recommend a similar scenario as this previous post Use case? Multiroom multi user?
