I am putting a completely new audio system in my car, I asked around and no one makes the dash speakers. I am going with components so I am going to put the tweeter in the dash. You could probably just put tweeters in there if you want to. I dont think you have a chance with the 3 1/2s. The factory speakers are a pretty tight fit as it is.
