Hi I am having a move round of my gear, and want to move my sub. so i am going to need a longer sub cable! I have just found in my garage an 8m length of component cable...."Canare v3-4CFB 605 75ohm coaxial cable made in japan" written on the cable. Could i use one of the 3 lengths for a sub cable? Is component cable ok to use? Thanks rickyd.
