I'm building a house,, have already purchased my Klipsch speakers and have to do my wiring this weekend for my home theater system and whole house audio system. Question I have is now that the electrical wiring is done in the house, I am concerned about crossing the electrical wires with the speaker wires. In most cases, I have to go past the electrical wires for the outlet boxes I am installing. Now then, I am putting in conduit and then will run my wires later. So my question is with having to cross the electrical wires, am I better off with metal conduit or will the PVC conduit be sufficient?
