What kind of wires are these??
I opened up a 4-gang wallplate in our kitchen with blank inserts to see what's inside. The attached photo shows the wiring inside. There are about eight of these wires hand labelled A-G. Does anyone know what these are? My best guess is that that they are speaker cables. There are in-wall Polk Audio speakers in the kitchen. But these don't look like typical speaker cables that I've ever seen. The wallplate is right above the counter.
We bought the house about 2 years ago, but the house is ~80 years old so who knows when this was installed.
