Hi guys, i'm new here. I have learned a lot from you guys as i have started to build my own home theater. Well, I am at the stage wire I need to run Speaker wire and rca cable, hdmi etc... My questions is this: I plan to put some 1 1/2 conduit for these wires, cables etc... Can they all be in the same PVC pipe. They will definitely fit because its pretty wide. Will I degrade the quality by running these together in the same pipe.
