How’s it going lads.

I am selling my car and started looking at 2009 A3s. The 1st one from 2009 has shocked me with its horrible sound quality.
As a driver of a 2004 A3 and a bass junkie, I must say my jaw dropped when I found out the only speakers working in that car were the little ones beside the dash (where the mirrors are, more less).
There is no bass whatsoever (even when manually set to full), bucketloads of trebles (even when turned down full) and the loudness it just as good as my mobile phone’s speaker (meaning it is super-quiet and "flat").

What a disappointment!

I was wondering whether that particular example was bad (as in the sound system failed) or is it normal in newer Audis?
Is there a quick fix for this terrible issue or is it a long process of checking the wiring and all that?

Please let me know – any advice is welcome!

Cheers.
