Modifying E91 rear door panel to accept speakers?
I am in the process of replacing the cloth cabin of my E91 LCI with a leather cabin and have hit a snag.
While the front door panels are prepared for speakers, the rear door panels are not. I have the speaker grilles on the existing cloth rear door panels available to me as the cloth cabin will likely be scrapped when I'm done. I can see on the inside that the cut-out is actually there but there are no mounting points for the speakers like there is on the front door panels. Since the speakers for front and rear are similar, I would expect them to require mount points. Are there any guides, suggestions out there for how to modify the door panels? Have looked but maybe I'm just not using the right search terms :-( |

So, you will either have to source it out of some scrap yard or get creative. You may be able to use something like contact cement to secure mounting points on the inside or even lift the leather and put them all the way through. |

Will check with the local scrapper if they have any speaker-enabled panels available first, though :-) Thanks for your input! |

I am about to do this on my wife's e90 as I am doing the Hifi to logic 7 retrofit. Her leather doors do not have the markings for the speakers but I found a set with the speaker markings to use. I will epoxy the mounting rings to the new panels and then cut the openings using my 335i door cutouts as the template.

Any thoughts on how to cut (what tool that is) and how to treat the leather? Was thinking an X-acto knife and leaving about a cm to wrap around and glue to inside of panel. |

Are you saying that they won't fit? I've looked up the rear panels on realoem.com and it seems that E90 and E91 shares the same panels.

If you are referring to the lateral side panels they are clearly stamped "E91" into the plastic inside, so they should fit. The rear seat and backrest look identical to the E91 parts I can see on realoem as well :-)

If you look at the photos in this link you can see the speaker rings.

Just to wrap this up - I contacted the place where I got the door panels and it turned out that they have a set with cutouts and grilles for speakers, so I'm gonna swap for these instead of going DIY.
Thanks for all the input and advice! |
