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.
