Thanks for the replies. Basically, I'm going to be re-doing a family members HT install. The FL,FR, RL, RR channels are pre-wired in-wall during a build. They didn't think it out very well IMO. The speaker outlet is right smack in the middle of the room on the front wall. This might actually work out to an advantage because I was going to do in-wall speakers and I can wire the center channel, drop it straight down and change the wall plate from a 4 to 5 speaker. After thinking about it, I can just cover the speaker plate with the sub-woofer.
Other then that, the outlets are not close enough to wall mount the TV. I think the best plan of attack is to get the wall mounted DVD bracket from monoprice. They claim to have cable management, the shelves are big enough to hold all the components. If anything else needs to be covered, I'll try the plant trick.
Oh, and the floors are hardwood, so I can't hide anything. Still might have to be creative in hiding the RCA sub cable and speaker wire from the wall plate to the amp.
Thanks for the suggestions.
