I recently bought a home that came with an ancient audio system already built into 4 ceilings. In total the system includes an amp, a switch, cd and cassette player, 4 ceiling speakers in 4 different rooms and 2 speakers (potentially one of them is an amp but neither is working) in the same room as the audio system. See picture's of equipment below.
only the switch is staying from this picture.
current amp that I'm hoping to replace with sonos amp
My short term goal is to keep the in-ceiling speakers but enable streaming (I'm going to remove the cd and cassette player as neither work). This lead me to the Port vs Amp decision. Ultimately I choose amp, which just shipped, as the current amp is an enormous heat producer and felt like something I'd want to replace sooner than later. In investigating further I'm now worried the Sonos amp won't be able to power the 4 in ceiling speakers through the switch as well as the ones in the living room (which will likely need to be replaced- I was thinking of going with a single Sonos one or five in that room).
Long term I'd like to add out-door speakers to the mix.
I'm an absolute novice when it comes to this sort of thing and just want confirmation that I'm thinking about this in the right way. Is amp the right way to go or should I have gotten a port. Can I add a Sonos 5 to replace the two speakers in the living room (if it turns out its not just a wiring issue which it very well might be).
Really really appreciate the help.
