Why do you think it is a tweeter? stock dash speaker is a 3.5". Delco did make some tweeters with a 3.5" mounting flange although they never put them in the G-body. Maybe someone swapped in a set.
My car also came with 3 1/2" speakers in the dash. I'm quite sure all Regals with any radio option at all came with 3 1/2s in the dash. Were you referring to a specific type of tweeter speaker or just a 3 1/2 in which you assume is a tweeter?
should have been more clear.. i was told that gm never put tweeters in the gn... but they are in there.. just wanna know if its factory.. audiowizard the doors will any 5.25 do?
Lets just say that the GM tweeters arent the best in the world . If it sounds ok to you then keep them but if you want better then go ahead and replace them with something better. I personally dont prefer the sound of tweeters reflecting off of windshield so I am not sure what to recomend other than a set of kick panel or door panel pods with a good set of components . I am sure the guys here will chime in and give you a couple of recomendations that you might consider.
yeah the 6x9's are the ones right under the pioneer premeirs. i wanna get new speekers for the doors and go with 2 10's i'm looking at the tornados. i really want the premeirs but they are real expensive
