AutoHifi recommendations to use?

Hello, I have tested six inexpensive subwoofers of the current AutoHifi magazine. Among them also Magnat and Crunch. But the newspaper rated all subs as good to very good and that probably can’t be true, right? Should I listen to the tests and buy a magnat for 90 € or one of you recommended? I really don’t know anymore … That the newspaper describes a crunch as a “sub with convincing performance” makes me doubt other credibility. MfG.
