Help me understanding my system

We bought a house a couple of years back that had an outdated AMX system. We disconnected everything but I would like to understand what we actually have and how to get some of the components up and running again, particularly the room speakers, without the AMX interface.

Here is the current situation: - we disonnected the AMX system and took out all the touch screens in the house. - each bedroom and a few others (kitchen, office, living room) have ethernet outlets and ceiling speakers (and two speakers on the back deck) - house is wired with Cat 5e - we have a bunch of extra Panja amps (4), a Sony receiver, Lexicon controller and amp Additional info: - there is a Lutron system but now isn't tied I to any automation or app - theater was disconnected from the AMX system, upgraded, and runs independently - security was disconnected, upgraded, and runs through it's own app

Any guidance on where to start, equipment I can reuse, equipment I should get, etc. to get the room speakers working and potentially link to an app would be great. I was wondering if we can use Sonos to get the speakers up and running, using the existing amps and receiver. Attached is a pic of one of the panels in the basement which could help.
