Hi guys, this has probably been covered many times before but I have looked and I can't seem to find a straight answer.

I have a 2016 BMW F20 and the stock speakers in it are awful. I have combed the internet (albeit probably not very well) and I can only find speakers that are plug and play - these are too pricey for me as I cannot justify spending £200/£300 as I don't spend too much time in the car. I have 2x 4" Hertz speakers from a previous car but they are not plug and play and I would not a clue how to fit them. I also cannot find anywhere where it says what size speakers my car takes. I only have the front door speakers, the under floor speakers and the parcel shelf speakers if anyone would know what size they are.

So I guess my questions are:
1.Can I get any speakers as long as they are the correct size and how would I connect them to the blue connecter in the doors?
2. How would I fit the speakers under the floor and in the parcel shelf?

Thanks,
Jack

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 https://www.leebmann24.de/ 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
2-BW-Tweeter-629 model


mids are called
MidRange-BW-635 model




for F20 & F21, F22, F23
Alpine labels (1 kit needed, it includes two badges)
65 13 2 230 426

only for F20
Left Door Trim with Tweeter slot
51 33 2 240 351
Right Door Trim with Tweeter slot
51 33 2 240 350


only for F21, F22, F23
Left inside trim 51 33 2 349 059
Right inside trim 51 33 2 349 058

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.

Hello,

I'll be doing the exact same thing in my 2016 F20 with base audio.
I purchased the HK speakers from AliExpress, probably from the same seller as Berseker

2x 4.5" for front doors
2x tweeters
2x 4" for the rear shelf
2x 8" underseat woofers

Got the Alpine window trim from the local BMW dealer (cheaper than on eBay too).
All together it cost about 250€. Waiting on the parts to get in now.

Berseker are the high tones too harsh now with tweeters in?
Been reading from different sources that the base audio EQ has boosted highs to compensate the lack of tweeters.
Have you done any coding?

actually I did not do any coding for now, just modified the treble\bass settings in the normal menu.
of course with the tweeters in, the "audio scene" is really completely different, even without amplifying anything.

in any case I would like to try what suggested (changing to "hifi" or "alpine" coding) in the future, I'm still trying to get more infos\feedback.

I did not purchase any new subwoofers and maybe now they are a bit "covered" by the newer front speakers, but I'm happy with the new setup up until now ;D

Very nice to hear it sounds good! Can't wait to get mine and install them.

Found some info about coding here if you want to play with it -> https://www.diymobileaudio.com/threa...n-most.437890/

Check post #6 for the recommended settings by that user.
Please report back if you do it

I coded as post #6 of that link, maybe a little upgrade on quality, but really little. I noticed however a small drop in the PDC sound volume. definitely need more testing though.

Do you still have the new speakers and tweeters installed? Have they caused any issues?

I'm planning on doing the same upgrade and I've actually already purchased the parts. However, the way the base sound system is set up has the woofers under the seats and the mids in the doors running in parallel, and so adding a tweeter results in having 3 speakers on 1 channel.

All of this means that there is a chance that at certain frequencies the total impedance is lower than 2 ohms which could fry the head unit (theoretically).

There is a lot of talk on this topic on the F30 forums so I wanted to check if everything is fine before installing them.

The parts i got :
2-HK-MIDHORN-956 on aliexpress
Skar Audio TWS-01 tweeters

I went with different tweeters as I can mount them without replacing the door trim.

I will add an update once all the parts have arrived and I've installed them.
