Will Focal Access 130 A1 5,25" / 60,3mm (depth) fit Audi A3 2004 (3-doors)?
The guy in the shop also supplied with adapter rings which says A3 1996+ on the package.

I am worried about the depth, I read somewhere they should be below 50mm, is that correct? Do I need different spacer rings?

Also, I have Audi Concert unit in the dash with none-bose subwoofer in the back, which I just found out. Should I consider upgrade the sub element and disconnect the rear speakers?
