Hello, I am currently settnig up my home theater, and for my front speakers I have monster cable XP3FHT THX Wires. For my surrounds, The runs are 50 foot, and 30 feet long. Will it make a difference if I use 16GA from homedepot VS 12GA SoundKing from partsexpress.com. Also, I have the JBL N24 Northwood series speakers as well as an Onkyo 595 DS REceiver. Will 12GA and 16 GA speaker wire work or how would I know if they're not compatible as in knwo the OHMS. Please help, I am trying to make the finishign touches to my hometheater THanks!
