Yep, just did this for dash speaker replacement. There's no airbag sensor in there that would set the bag off. There is the bag itself - just don't poke a hole in it. I get your trepidation - I am not fond of yanking off any panels. Here the two gotchas I found:
- When you pop the panel off the two clips, it takes a lot of force. When one of mine let go, I pulled it too far and broke the microphone because it reached the end of the cord and got pulled apart. The good news is that they are very cheap ($23 at the dealer, or less elsewhere). But try not to pull the panel more than 2-3 inches away when it pops loose.
- The clip to release the bungee cord is not that easy to open. You have to pry down the barbed end, toward the panel, while you slide the panel forward or the clip backward. See pic below.
