I am installing an aftermarket amplifier in my '02 E55 with the 8 speaker Bose system. I will be replacing the front and rear door speakers as well and need info on the size of the rear door speakers. I have read conflicting postings that state a 4" and a 5.25 will fit. I am hoping to stuff a 5.25 coaxial Focal 130CA in the rear doors, they have a depth of 2.5". Can anyone confirm that they will fit? I will be using Focal 165 V2s in the front doors, I have read postings that indicate these 6.5" speakers with a depth of 2.85" will fit. I am trying to avoid removing the door panels twice - once to check and again to install. Any definitive info on this subject will be much appreciated. I have also posted this on the Audio and Telematics forum.
