I hung mine under the glove box. I basically pulled up the sano pad and drilled holes into the bottom and then attached the changer mounting board to the underside. I then put the sano pad back down so, that you can't see the screws. I then mounted the CD changer on the board so, that it is just below the lip as you look under the observers seat. This also saves in the long cabling to the drivers side.
