I bought these to install in my e92,however, they will not fit if bottom installed it rubs against the window with factory grill. I do not like the look of top installation. I can send pics of the top installation please pm me The speakers were installed then taken off only used for 5 minutes and they sound amazing. I paid $750 but will take $399 for a quick sale my loss is your gain.
I have attached a link below to focals website which gives more details about the speakers.
