Audi A3 Audi Sound System fault?

[Flying Scotsman]

I stated it was OK, but not B&O quality. I have a 2017 S3 with the Audi sound system and it is not capable of driving the sub woofer when the bass is cranked up. I personally do not like when boomy bass will overwhelm the sound, but some like that and the Audi sound system amp is not capable of providing the power to do this, it will clip. For me the Audio sound system is OK for radio music. I leave my home sound system to deliver audiophile quality and yes it cost a lot of money. If I told you the amount, you would think I was bonkers.

That's low-hanging fruit if ever I saw it.

So spill the beans, Flash Harry - how much did. it cost?

Well curious Phutters and voyeur of low hanging fruit......I do not like to spill beans or am a Flash Harry. That is why I will not list the cost to be ridiculed by some on how I spend my money. I just like the best home sound reproduction that I can afford, as any car sound system leaves a lot to be desired due to a car's environment, voltage, sound staging etc., end of story

Nicely swerved

A chap's woofers are very much his own business. I respect that.

Just noticed this thread. I’ve got an A3 S-Line 19 plate and mine does it too. Best way I can describe it is like someone turning up the volume and then down again (like it’s a fluctuating). Very annoying. Seems fine on Radio though! Does anyone have any updates on this. Also, I believe my sub is in the boot under the boot flooring but have no idea if it can be adjusted there or not????

Yeah that’s exactly the best way to describe the issue, just random fluctuations in volume for no reason. It’s not a setting and it’s not an individual fault with your car. Looking over forums I’ve seen hundreds of people with the same issue but Audi refuse to accept there is a fault. It’s baffling. I’ve 100% given up on mine and just listen to the radio now which works fine but isn’t my favourite thing in the world.

I found something somewhere on how to reset the MMI and it seemed to work on mine. Music seemed a lot louder.

This link shows you how to do it. Seemed to work on mine. Try it and let me know.

agreed as that sounds the same as mine. With lockdown I’ve not taken back to the garage yet but I will be getting it sorted before my first year runs out. I’ve not tried the MMI reset yet either so will give a go. Has anyone actually had this properly fixed?

Hi everyone, nope still waiting for a fix for this and I can’t believe this problem has been going for a few years now and still nothing!!!
Any news from anyone else following this ?

It’s Most likely due to a multi channel amplifier struggling with the demand. Takes a lot more power/move a subwoofer than a tweeter.
On lower end multi channel amp, let’s say 5x100w, the total 500w is shared across all speakers plugged in. When the sub asks for 400w then that only leaves 100w to the rest of the speakers.
A good 5x100w amp will give 100w to each channel even though the sub wants 400.
A good setup will have an individual amp per speaker but that gets expensive.
In my youth I had a car with a SPL blow your windscreen out level sound system so understand how it all works. A bit more mature now but the same principles still apply.
Cheap amps vs expensive.
I’ve had a few a3 courtesy cars and have noticed this on all of them apart from the b&o cars.
Even my old a6 did this.

Does sound like this issue.

I don’t know when they changed this but my PFL with A.S.S.
was fine up to a one off volume 22. Depends on the type of music being played but inappropriate load balancing and amp protection could explain it.

So is there a fix or something that can be done to help this problem? I’m fed of waiting for Audi to get back to me. And I’ve got this current car for almost another 3 years.

Seems like there was no update. Having a 2019 A3 with *** and same issue when coding in the Subwoofer + Bass Dials since they removed the seperate Subwoofer Menu.

Going to test with stock firmware also but this is cleary a way to ruin a car.
