Bubble above bay door

[relic57]

Noticed this the other week. Ripples and bubbles above the bay door. They do not push in so I don't think it is de lamination, but could be wrong. Anyone have any idea about this. Thanks

It looks like delamination. check your caulking seal around the speaker. The discolouration of the wall goes over past the speaker.

This is a pure guess, but based on the positining picture, I would check the speaker. The lauan behind the fiberglass may have swelled if water is getting in at the speaker.
