I've never had an amp in my bedroom though.
After I moved out of my parents' house, I haven't had an amp in the bedroom either.
I lived in apartments for about six years before finally getting a house, and did most of the playing in the living room during that time.
I got engaged shortly after I moved into my first apartment, and there's no way my then fiancee would have allowed me to stash a guitar amp in the bedroom (or guitars, or any other guitar-related gear). Thank goodness we had closets in our living rooms.
Now I'm allowed to keep my guitar gear anywhere in the house that I want, as long as it's in the basement.
