I still consider myself a newbie so bare with me... I have Def Tech BP8b's for my mains and I just received Def Tech BP2X surrounds for X-mas. I currently have 12 guage speaker wire running to my mains. Should I still use 12 guage for my surrounds or should I use 14??? My problem is that it will be hard to hide 12 guage under the carpet when I run it to my surrounds. Will I hear a difference?? Thanks!!
