I have serveral models of Klipsch in wall/ceiling. What is the secret to getting the grilles put back in once the speaker has been installed? The came out of the box with the grilles in so obviously they should go back in once I get them put in to the walls/ceiling.

I currently have in-walls for my fronts (SCW-3s) and surrounds (SCW-1s). I want to replace my center SC-1 with an in-wall and I'm looking at the SCW-1s. My questions are: 1) Has anyone used the SCW-1 as a center? How does it sound? 2) Is the SC-1 suitable for a center? 3) Can I mount it sideways (landscape as opposed to portrait)? 4) SCW-1s are sold as a pair. Can I mount two centers? If so how do I wire them to my amp (Denon 2803 with one center speaker wiring terminal)? 5) Any other suggestions for an in-wall center? Thanks.
