I'm installing a Pio 435XDE, Denon 3805 and Genie 5.1 package, and will be routing all cabling through to another room. I was going to make a run in the plasterboard, insert some trunking and run all the cables together into the other room. It will basically consist of the media box leads (x2) the speaker cable for all speakers, the sub cable, and an aerial cable. It will not carry a power cable. My question is - is it OK to run all these packed tightly together in the trunking, or will it cause interference? Also, does it make any difference if I use metal or plastic trunking, and if they should be separated, which ones should be apart?
