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?
