Rattle/vibration caused by subwoofer

[Northwoods]

I'm hopeful someone can help. Our '21 Yukon Denali has a rattle in passenger side far right side of dash. It occurs when certain deep bass sounds play from the subwoofer. GM replaced the right side door speakers but no help. Any ideas?

Turn the radio down?

Seriously, I’d be looking for loose bolts or screws. Might need to get a lighted inspection mirror to look around under the dash. Make sure nothing in glove box can rattle.
