My first S class and basic audio upgrading…

Hello everyone,
Does someone have experience with upgrading basic audio?
Who ever i ask, everyone said it cant be done like its a space shuttle of some sort… getting nervous.
Sound is very good(dont know how many speakers but its enough for decent quality), the thing is they are too quiet.
Any ideas?
and im not a cheap person, trying to get it done for 400€.

Thanks!

If you're wanting to upgrade to 4D sound, there is at least one person in this forum who did that - it was quite the ordeal if I remember his post correctly. If you're wanting to upgrade your base 3D system, you might consider adding a subwoofer; several people in this forum have gone that route.

You're not going to be able to do anything for $400 Euro. To have any meaningful benefit you need to at least add a zero.

What content are you listening to? Try listening to Apple Music or Tidal through the car's online music (not CarPlay), the difference in sound quality is huge. I had a subwoofer in my W222, but the 223 doesn't need it...its still in my basement. Even that tough isn't going to happen for $400. My sub and amp were $1,200 installed.

To correct myself, what i meant is im NOT trying to do it for 400€ because i know its much more expensive job.
My car has basic audio, so no burmester at all,
bass is ok, quality ok, just need it louder.
It would be cool to upgrade atleast to regular burmester, doesent need to be 4D

I wasn't aware you could get a W223 with anything other than a Burmester; whether it be the base 3D or upgraded 4D.

I'm assuming you have the 9 speaker 125w system. Find an audiotech fischer/helix/match dealer, you'll probably spend 3k euros for sound deadening, high end helix speakers, match amp/dsp and dsp tuning, Amplifier plugs into the back of the head unit with the Match plug and play wire. I'd suggest getting "Burmester" grills from Aliexpress too. If you think the standard system is good you'll be amazed by the outcome of the above.

Yes, i think so,
what i meant is that the quality is not that bad, not the best of course, i also have new E class with 4d and i dont find it anything special…
Bowers & Wilkins in Bmw g30 2017+ are by far the loudest and most powerfull ive experienced, burmester is funny compared to b&w.

Then I would suggest taking the route I said, you can probably do just amplifier upgrade for 1000ish euros but if you've spent all this money on an S Class you might as well spend a little bit more making the sound system the best.

The issue is you will have to go to either Austria or Slovenia for an authorised dealer. If you have a local audio shop you trust you can buy the parts on ebay from AllWoods Audio, give him your vin and he will propose a full audio upgrade for you and explain what the other options are.
