Always check your local codes before bidding on one of these systems. Some jurisdictions require the speaker wire to be run in conduit which changes everything.
The one I updated had been installed in the '50s and it was up to code. That's the reason I couldn't easily change the boxes (I thought I mentioned that). The cable was actually shielded.
