I bought a house a few months ago and I’m still trying to figure out all the wiring. I found these coming out of a cabinet in the kitchen.
I think (?) the black one is a cut-off coax cable. There’s a LOT of coax in this house, so that seems straightforward (but I would still love if someone can confirm!)
I’m not sure about the other ones. They don’t look electric, as I’d expect electric to be black + white + copper, like the rest of the house.
There is supposedly a speaker system in the house (I see speakers) but I haven’t figured it out yet. Could that be power for the speakers? I’m not familiar with speaker wire setup. If it’s speakers, why would there be so many wires?
Left most looks like cat5/6 Ethernet cable but hard to tell from pic. If there’s multiple tiny, colored wires, solid and a striped, it’s that. Next one is RG-59 coax. Others look like speaker wire of some sort but I’d test with a multimeter to be sure they aren’t live
Edit: RG-6 to RG-59. Hard to tell from pic though
