Sooo...
After the energy and the confidence that Taffy gave me I did a similar job.
The door has three section, upper middle and low.
I only removed the middle and the low.
You need to start from the middle.
The middle is kept in place by a plastic stud on the door side, just under the locking system, and yes. Three velcro (Hook And Loop) pieces. Velcro. Nothing else.
Once removed this (be prepared to re-glue the velcro on the metal bar on the door since the glue in my case was "gone"), you can concentrate on the lower part.
Easy. Another stud on the side, two or thee on the bottom and one close to the door hinge, where the speaker is.
On top, on the upper part of the speaker grill, on the left side, there is a tiny screw (you can see it in the last pic). That's all.

In my case the speaker was a JBL GTO. Looks like they mounted what they had in stock. It seems that in my case, there was a custom frame around the speaker.

In case you have doubts on your chassis number... you can find yours randomly around. In my case written with a marker on a piece of paper tape

All this since I was hoping that the speaker was rotten, while I guess that simply the audio system I guess is crap.
