i recently upgraded my base system (no amp, no tweeters, paper speakers) on my F20 by purchasing a pair of 4.5 speakers & relevant tweeters from Aliexpress
+ the trims needed to install the tweeters directly from a BMW spare part dealer (but you can find the same on as instance) with very nice results

very satisfied with the upgrade

for a very base upgrade you could also install only the tweeters.

tweeters are called

mounted myself following some tutorials on youtube. first time it's a bit tricky to unmount the door trims, second door that's a bit quicker.
