Ha Ha, yes I agree with you, "clunky" at best. This time for me, I believe the looks overcome the function so I will be doing the retrofit.
Heres a pic of the Bezel I made for my E39, she's in the garage torn apart a bit so when the dash is armor all'd there is no color difference between the bezel and the dash. It worked out pretty well, but I have been working in the car audio field for most of my life.
I did the titanium inserts at the same time.
I will also be doing a JL SB in mine, everybody I have talked to in the industry says its the best way to go. The only thing I dont like is that it comes with a W1, I may switch mine out to a W3, I dont think theres enough room to fit a W6.
