I am about to setup some analog connections from my PC sound card to my Onkyo receiver, and it is going to be roughly a 15 foot run, with a potential for interference since it has to run near a few power strips and a bunch of other cables. A 3.5mm > RCA connector will be necessary (I am going to use a 6" one,) but I am not sure what kind of RCA cables I should use from those to the receiver.
I would otherwise use RG6 with RCA crimp on ends, but it has to go around a few tight corners, and a total of 6 cables will be necessary, so I am not sure if that would be ideal as it would make a mess. That said, what is the minimum wire gauge I should look for in doing this setup? Or should I just bite the bullet and make some RCA cables from my RG6 spool?
