Review on C2G 29175 Velocity Speaker Jacket by Robert Worlds

This is a good heavy duty professional grade cable, similar in size and outer jacket to a 300v power cord. I bought a 500ft spool thinking I was going to run a lot of speaker wire but unfortunately I mostly ran the wiring in the wall and only used it to go from 2 mesh to speaker mounts which I put in the ground under a brick one fireplace installed . (Plasma above on a brick). I am wondering if I can use this interior piping for some exterior applications?
