Don't worry about it. It is likely some proprietary Chinese home theater in a box garbage. The wire doesn't even look like speaker wire.
If those wires all run back to a central location, and you're looking to use those wires for new speakers, then just chop off the proprietary ends and connect the bare wires inside to your own speakers.
Be aware, that these wires typically are very slim of 18 gauge or similar. They may not be appropriate for a 'good' setup, but will probably work just fine for years to come if that's what you want to use. Trace the wires back to where they came from and show us a picture of the other end of things.
