@Abhijeet, are the wires detachable or they are fixed? If detachable, how to you attach them to speakers? If attached, what do they have at other end or they are just bear wires at the end? Propiratary connectors mean that the end are made such that they can be connected to components of particular brand only. This was common with mobiles, and is till seen with brands like sony. If they are there, you need to cut wires to make usable which I won't advice if you are not sure about what you will be doing. If possible ,post some pictures. Of ends of the wires.
