Removing stock speaker grills

[Crowbar]

Does anyone know how the basic speaker grills are removed on a 2015 boat. I dont want to break anything by prying. There are no visible screws. I have the stock stereo.

S series? There should be 4 screws.

I had to pry mine up with a flat head screwdriver. They will pop off. Then there are 4 screws securing the speaker.
