Glock

I bought the Promedia 2.1's a few months ago. Now before you tell me to go to the Promedia section, it's an issue with the wires. Well, the wires have been twised up a lot, and now that I've straightened them out, I notice that the sheathing is gone in some parts of the wires. It's not frayed as in wires are sticking out broken, however, the sheathing being gone in certain places concerns me. How can I get a new input wire from Klipsch for my 2.1's?
