Sorry to jump on this a little late, but I found important to defend the Blaupunkt PA amplifier line.
My actual system consists on a PA4100 for the front/rear mid/highs (Focal Polyglass 165Vs) and a PA275 for my 10 inch sub (Blau. ODw1000).
Dismiss everything you have heard or read about the class "T" amps from Blau. They are fantastic. They look great and are really small (this was an important goal, as I wanted my Peugeot 307 install to be the least intrusive possible).
Maybe I am not a total audiophile but have some experience with such stuff, some friends have McIntosh amps on their cars. I really think the PA line is comparable in sound quality to some very expensive ones. Maybe I'm not a true audiophile, but I think I have some experience with high quality systems and I believe that the 2001 PA line is very reliable and sounds really excellent.
