Hello, I have the following question: n kumpel has left me his no longer used infinity 6500cs speaker cheap (very good) today. I don’t know exactly what I can do with it, but since I want to do something in the next time anyway, in things hifi, I thought, I just take them with me for n appel and n a well, at least on the things there is hardly anything on it, except: 165mm two-way system power handling: 90w rms, 270w peak now the question, they fit somewhere in my a 3 8l pure? or do I have to make something for it? do I need for the dinger nen amplifiers? what is to think of the speakers? are the what or rather less? I don’t know exactly, but I think the dinger tweeters are. in which tweeters and subwoofers, etc differ I get so far. but what do front and rear speakers differ in the car? on what matters? many thanks, mfg flxx
