Pretty sure it'll be the same as my 2003 31C. Inside the cabinets, the side panel of the speaker enclosure is stapled in. You need to just get a tool of some sort in between the edge of the panel and the front/back/top/bottom of the cabinet and work to pry it free. It's a pain to remove and more than likely will result in a little bit of damage to the panel. The good thing about the damage is it will all be hidden inside the cabinets.
