Well I have some A/D/S 320, and 325 component speakers from like 1990. They were the best speakers I had heard in a car, but now I have been converted to Higher Fi how do you think they stack up against the newer speakers? I see them going for $300+ a set in the used market. I love vintage Polk sound, and nice silk tweeters. Should I sell them, and get a set of mid-line coax's? Should I keep them? I can mount 5 1/4's in the doors. I have a PQ-10 amp to drive them, and a nice older Alpine head unit. I listen to the radio for the most part, and don't care about not having mp3's.
