Thanks for your insight and suggestions. I had a feeling that it would run pretty hot. I guess that I will just have to splurge before I get these, and get a nice, new rack to hold them in. I need to figure something out anyway to keep my kids out of the equipment. I have a mentally challenged one year old that loves buttons and wires, so I am thinking about a rack with closing doors on it. Would I need to provide space in front of the amp, for ventalation as well, or would having the face almost touching the door be too close?
