Hello
I am a new owner of a 2009 328 xi.
I come buying the details that I see.
Now I find that it has a subbuffer and a bad rear speaker.
He makes a strange noise as interference.
The car has the VA S676 hifi
I would like to know if it is worth buying the originals, or making an upgrade
What do those who know recommend me?

I also have another detail, before this e90 I had another one with an Audi stereo.

It was pre lci but with the radio from a 2011 335 encoded stereo.
It seems to me that it sounded louder than this current hifi, could it be because of the subbuffer? or some kind of code?

Would it be worth bringing another radio 2011?
Thank you

It's because BMW stereo's are crappy in the e90 series and beyond.
The amp is weak and the speakers are cheap .
In a 676 system the outputs of the Head Unit are analog and there
is an analog harness so you can add aftermarket stuff fairly easily .
The BMW head unit is a decent source for aftermarket amps and speakers
expecially when programmed for Hi Fi.
I had and E46 and the stereo was good in that from the factory with the factory upgrade.
Part of this problem is the trend to use small door speakers .
BMW cheaped out on the e90 stereo's and beyond.

ooooo very very thanks
Yesterday I bought a sub and an original hifi speaker, to at least leave it sounding good, but I'm going to read this calmly to see if I can improve it.
Thank you so much
