we got a 2021 A3 Edition one, mainly cos of the extra bits on there (nicer seats,parking aids,black trim,wheels) including the B&O sound system, however the SUB just seems to sound like its blown, it has no punch or depth to it, the rest of the speakers are fantastic, has anyone else experienced this ? we have taken it to local Audi shop and they said cant tell, we had the car about 1 yr think would bed in then get better
