You can use the wire from Mogami like the Neglex Quad 2534 or the Canare version of it and put Neutrik XLR's on each end, these cables and the Neutrik ends are great for these types of applications.
You can always wrap the cables with a "flex wrap" that come in a myriad of colors. I have used these types of cables when my mono amps are next to the speakers and preamp is quite a ways away on a side wall.
There are companies out there that sell these cables in bulk and some of them will actually assemble a set for you with the Neutrik XLR's.
