I looked through the forum and can't find anything about the speaker sizes in the 165 except that the front is a 3.5"? though some say 4". If I was near my car I'd just go pull some covers and measure, but since I'm not near it, and also because this would be a useful for future reference, I'm hoping some nice folks might be so kind as to tell me the sizes of the rears as well My car came with no speakers/head/amp so I'm starting from scratch here, so any help is appreciated. Oh, and I'm asuming the tweeters are 1" as well? Tnx.
