The rubber mat just pulls up from anywhere you can just get a finger under it and pull it without worrying about breaking clips.
The plastic part underneath (the tray) you will need to remove the two 8MM bolts IIRC for size in the back and then once they are removed, slide the tray forward a tad bit towards the windshield and then up. Be careful because the speaker will be attached to it. Takes about 5 minutes tops.
