I have no plans on selling the speakers, I'm sure with a little bit of effort and time/modification, I could get the 3.5" in the dash. I love the way that the highs sound coming out of them. I have never had a true set of tweeters for the fact that I never liked the way they sounded in anyones cars that I have heard in the past. I guess I am going to mark this one as a no go. lol.
