E90 basic audio fix/upgrade
I have a 2009 E90 323i with the most basic audio. No rear door speakers, no front door tweeters, single CD deck with no Bluetooth music.
One of my front door speakers is ailing and buzzes sometimes for no reason or splats on bass hits.
I'd like to replace both door speakers but not make any other changes to the setup.
Can anyone recommend some good quality replacement units that fit in those tiny housings? I'm not overly cost sensitive but I don't want to do anything much more complex than swap out the factory speakers for slightly better units to give a marginal improvement in sound quality/volume capability.
