Mounting mic panels and routing snakes

Hello, I have a question about the proper way to attach mic panels to the wall, and what would be the best way to route the cables through the wall. I am unsure of how to attach the panels, because the spot that the panel is going into has no studs behind it? Also from what I understand that I don't want to run the cables straight through a wall because the direct path it will create for sound, so I thought that I would have both panels cabling run through the inside of the wall and exit together through a single hole. In the picture the red dotted panels are on the opposite side of the wall that your looking at. The walls are steel stud construction so I could just run the cables through the holes in the studs right? Also what is the best way to block the sound around the snakes coming through the hole? I have used the search function, but could not find an answer. If some one could help me out I would greatly appreciate it. Thanks

anyone?

Its only been a day, have patience, and hang tight young spud. You may wanna follow the guidelines to posting, and post this in the installation forum for better results as well. :D

didn't realize there was an installation section, thanks

I'd add a piece of (finished) wood on the wall using special GB screws (dunno what you call'm in the US). Add the metal stageblock onto that wood. Snakes goin' through the wall means cutting and therefore compromising it. Since the wall is already up, adding a tube system in the wall is not possible anymore. Therefore I'd just put the snake through, secure it and seal it of with sealant.
