A common issue with these cars is failure of the rear speaker deck speakers. The cheap paper speaker cones bake in the hot sun where they eventually break. Someone discovered Monsoon speakers from mid-2000s Jetta and Passat are an almost direct replacement, and are much beefier than the stock speakers.

I bought a set of speakers from him on ebay and got started. Removing the rear speaker deck involves pulling the rear seats which is a fairly quick process. You also have to remove the C pillar trim and rear deck. Unfortunately the felt on these parts is pretty delicate at this point, and starting wrinkling/delaminating where touched. Also most of my C pillar tabs/screws were either broken or missing which is weird.
Doing these jobs you can see how much sound insulation is in this car. The thick rubber matts under the seat cushion, more insulation in the C-pillars. Even the trunk walls are treated.
The speaker deck takes a little bit of modification to fit the new speakers. You need a heat gun and a thermos to open up the inside to make room for the larger speakers. Otherwise this mod is pretty simple.
A busted old speaker.
Here's my brother sealing up the new speakers.
Needless to say, they sound much better. A great upgrade!
Made a video for this too!
A beautiful car! Love Bimmers ????
