I'm guessing your fireplace is like ours. You pull the wood-looking (they are really like styrofoam) panels off, then take the screws out of the marble facade. From there, you pull the fireplace out. That is where the sub woofer is. One of the screws holding the marble pieces in was in kind of wrong and it kept the fireplace from coming out as easily as it should. When it went back in, we changed the position of that screw.
