Door Speakers - Max Depth 3" or 2 13/16"?

[KevinH1990]

According to this document: http://images.wikia.com/boxster/images/b/b6/Boxster_speakers_update_article.pdf

Speakers of 3" depth or less will fit. I have not tried this myself, so take that with the proverbial grain of salt. You might want to check the specs of the speakers that the author used to see how deep they were.

I have not upgraded my stereo system yet but it is on my list. I found this info that might answer your questions. If you convert the MM to inches I think you will have your answer.
