Hey, The speakers on the fox are a bit of a nightmare. To get to the speaker there are I think 5-6 screws located around the door panel, Some are on the underside and the rest are located in a few more visible places. The speakers are for some stupid reason riveted into the door meaning that you cannot just remove some screws and have a look. There should be a wax paper like cover under the door panel to help keep thinks waterproof, you might have to create a gap in this so that you can see through a hole in the bottom centre of the door where the window motor is placed, This will be the best
