Interior door panels and how they attach to door frame

[neliconcept]

Hey guys,

So I found a rear left door to replace my damaged one from the same year as my x5, however It doesn't have premium sound, my question is, the two speakers in mine are attached to the panel and should be interchangeable to the door frame that I'm getting right? I just wanted to double check!

Thanks!

I'm not sure about the X5 but on all the other BMWs I've worked on the leather panel where the speakers are is attached to the panel frame from melted down plastic tabs. I've seen people drill out the plastic then use screws to attach the replacement panel to the frame.
