I am building an entertainment center for my living room. I have already built and installed the lower section but I discovered a problem with the upper section. The two narrow shelf units on both sides will sit in between studs! The center upper unit will have six studs available to secure it. I was thinking that I will screw some cleats across the top joining the two side units to the center unit and screw from the two sides into the center cabinet sides. Would you think this will be enough to secure the two side cabinets? Also, they aren't really that deep and I was wondering if they are gonna be stiff enough for the sides to not move. I was thinking about trying to somehow secure the face frames to the top of the lower unit. Any suggestions on that?
