You da man :) Sorry I used the incorrect terminology I am just a ambitious D.I.Y'r. I understand the way the walls and truss are constructed and laid out and how the inside of the walls are. I would go underneath and I could have gone underneath as this is a ranch house on 12 courses of block. But a few years back me and my dad finished the basement by framing it all in and then drywalling everything. This rules out going under the floor as it is now inacessable.
I beleive I am going to head up into the attic and take a look at the layout and where the walls begin and end. I am sure I can run the speaker runs through the attic and down the walls. The best part is that there won't be any electrical lines in the walls I need to go into. This house was built without any celing lights of any kind and the electric baseboard is on another wall.
Like you said, if I can get between the vapor barrier side of the insulation and the wall it shouldn't be to bad. I may be able to "borrow" a fish line from one of the network guys at work :)
