I have 12 gauge speaker wire that I have ran across my ceiling from every speaker placement to the receiver. However, my 3 year old son has seen to it to pull off the speaker wire, and was wondering if there are better options. I live in house built on a concrete slab, so going under is not an option. I have thought about going through the attic, but after being up in the attic it doesn't seem like a promising option. Any thoughts?
