In an unusual flash of common sense, it suddenly occured to me that I could have my cake and eat it, too: I could get a large sub (the Adire Rava) and put it on the other side of the room, IF I ran a cable through the wall from the receiver to the sub. (If I tried to run a cable over the mantle of the intervening fireplace, I would be single again tomorrow.) This leads me to the following question: What type of cable should I use to connect the RCA jack wallplates that will intervene between the amp and sub? I don't want to spend more money than need be, but since I would like to get this right the first time, I would prefer to err on the side of better quality if need be. Any suggestions would be greatly appreciated!
