Hey all! I recently installed the BavSound stage 1 speaker kit into my 2011 E92 M3, and the results are just stunning! The speaker option I had OEM was simple base stock, even missing the possible rear panel tweeters, so this upgrade was really really dramatic! This has changed my daily driving so very much, that I wanted to share it out with the group here. In addition, I created up a detailed installation guide for any tips I learned while I did it, so I could share that back with the forums. BMW does a really fantastic job in speaker layout and sound design for the cabin, but I don't think anyone (regardless of what speaker package you got) will argue the speakers themselves are of the highest caliber. (sadly disappointing actually) BavSound is the single highest bang for the buck upgrade I have done yet to my car! Absolutely worth it, without hesitation. The guide is attached below.. let me know if you have any questions? The file is too large to attach, so here is a link to the doc: http://1drv.ms/1aP3Tlm
Great write up. something I have wanted to do is improve my sound system without changing the stock appearance. I added a Pono music player recently and I am blown away by the little player. Darrin
