So...our stereo which was wired to both indoor and outdoor speakers died on us (It was like 30 years old.) We are moving towards the 21st century ha ha and have purchased an Echo Dot and Amazon premium music streaming service (trial basis.)

What we are trying to do is have it where we can listen to the same music both inside and outside at the same time. We have wifi that works well on the back deck. So basically if I am inside cooking and Leslie is grilling outside we can listen to the same music. I'm just having trouble figuring out what we need.
