My guess is that it was for some kind of all-in-one surround kit. The DVD/Blu-ray player head-end would have been under the TV. The bass box containing the sub and amp was hidden at the back of the room.
If you can't make use of the cable either as Cat5 or as a pull wire for your own cable, and it's plastered in, then get rid.”
Actually now I think about it...
There is another thread on here where a DS member was talking about a Panasonic system he had obtained. That system has a control cable that runs between the disk player section and the sub which contains all the amplifier gubbins.
Had a quick google and the images of that cable do bear a resemblance to the OP's image. But without the bit sticking out the end where you can see the ends of the wires (unless that has been pushed out of the body of the plug for some reason?)
So it is quite possible that the OP's cable is something along those lines. And without the bits that the cable plugs into either end then probably not a lot of use. Unless he wants to chop the connectors off and crimp a RJ45 plug on each end and use it as an ethernet cable. Assuming it really is using CAT 5 or similar cable. It might be CW1308 phone cable (very similar colour coding to the wires) in which case only good for a phone extension
