I've been thinking that the Audi Concert stereo in our 2007 A4 S-Line Cabriolet sounds a little bit weedy.
I have a 2003 B6 A4 Quattro Sport saloon that has the optional extra Subwoofer on the rear parcel shelf, and it sounds miles better, even though the head unit in that is the older version of the lowly Concert stereo.
How easy is it to maybe replace/upgrade the rear speakers in the Cabrio to something a little more beefy? Also, can the fronts be swapped out easily or are they all moulded into the door skin?
If so, what diameter/depth speakers would I need to get?
I'm sure there are far better head units out there that will fit but I'm thinking that the speakers could potentially be upgraded for far less money.
Any info would be a great help...
