i have been working with blaupunkt stuff for a while now. I looked into the PA series amps. The technicians at blaupunkt told me with and PA series amp you have a chance of losing you FM radio. So if you listen to cd's all the time or don't mind not having FM then i say do it. This problem they had with that series amp was never fixed and they now have a new line of amps. For Christmas I got 2 PCA 450's they are 4x50 or 2x150 at 4 ohms rms. I also got the same speakers you have listed but the OverDrive Line they handle a little more power and over a high grade speaker. The ones you have listed will be just as good. If you have anymore questions pm me or email me at
