If it's just laying loose, you can cover it up with
braided tubing This is just one example, there are other companies with a broader color selection. It can be capped off with color marching shrink tubing. I ended mine with 7.1 surround color scheme shrink tubing (or as close as I could get). Scroll thru the pics in my HT. The very last pic on the photos page shows my sub wiring. I couldn't get a high enough shrink ratio to go over the plug ends and still shrink to the wire diameter, so I left these unfinished.
