Well, for those of you interested, I finally covered my amplifier rack in carpet. Turned out really well I think, but unfortunately the carpet is a shade lighter than what I hoped. Oh well, matches close enough. The funny thing is I'll probably be doing it all over again. I may be adding a subwoofer, and if I do I'll have to make an amp rack that will house two amplifiers instead of one. I don't mind though, the install is the fun part.
