I'm planning to run speaker cables from a new outlet at an uninsulated wall to a new outlet at an insulated wall. I've already run Cat5e and coaxial cable to the uninsulated wall, and am comfortable with the process. However I have a concern with the similar task of running cable through an insulated wall.
Other than installing a low-voltage box at the outlet, do I need to protect the cable that will snake through the wall/insulation in any way? I have a concern that the cables and their slack will pose a fire hazard since they will either run through the insulation or between the insulation and drywall in an untidy fashion (i.e. not secured to joists/studs for new work). Should I run the cables through a plastic tube/conduit for extra safety?
The speaker cable is CL2-rated, so perhaps my concern is unwarranted.
