Anyone know how to remove the grill to access the ML center speaker in the GS430? I am hearing some crackling sound at certain frequency coming from the center speaker and want to confirm it the speaker is failing (the sounding material deteriorating). Also, if anyone has a used one I maybe interested if I find the speaker is failing.

I believe the grill is just held in wit some clip and pop out. Use a thin blade and pry it slowly.. I could ot find it showing up in the service manual.
