Not sure if this should be here or in DIY but anyway.... I have already made some basic cat 5 FFRC cables out of bog standard cat5 and have been well impressed. However, I know plan to make some proper cables from the Maplin VB20W stuff that's recommended. I plan to vary it a bit and have 4 cables per speaker, one for each terminal. Both reds and both blacks will be joined at the amp end, effectively biwiring. That's not the reason though, I want to do this so I can easily biamp in the future. So, my question is, do the cables really need to be twisted together as I have some fairly long runs and it makes it difficult to calculate requirements. Is the plaiting just for tidyness? I mean, the conductors are all twisted inside so how about if I run all 4 cables together and tape them every 6"? They'll be in ducting under the floor so looks are not important. I may just plait the ends for appearance,. I'm just a bit worried that the twisting is a key element that I am going to remove.
