I am having a new family room built and I am running the in wall speaker wires. I am doing this on a budget. I bought jacketed in wall approved cable for the surrounds with wall plates. The electrician is about to do rough in. I could drill separate holes for my speakers and I know that is probably the right thing to do but I get different advice from different folks. What kind of problems would I run into if I ran the speaker cable through the same holes as the electrical cable? This would save some hassle on my end and the construction schedule is keeping everything very tight timing wise. All of the cables are insulated.
