Summary: These speakers I used to resupply the car audio system. I installed them on the center panel and on the rear trunk lid (crossover vehicle). Total was 12 speakers with the subwoofer, it became possible to enjoy multi-channel sound.
Conclusion: Speaker fit in my 86 Pontiac Sunbird convertible but it was a real pain in the butt to mount the speakers. There is lots of room under the dash but there is no real good surface to mount the speaker and they need to be deeper than the originals because of the tweeter dome in the center0.
Conclusion: Damn good speakers, clean-clear-crisp sound everyday.....I have 4 of theses along with 4 T1693's...been pushed by T600-4, I love the sound & I stay getting compliments on how clean my ride sounds.
Conclusion: These speakers definetly exceeded my expectation! People complaining about them not taking bass very well are idiots, a 3 inch speaker isn't made for bass. It's made for some mids and the really high tweeter. These speakers scream very loud and verry clear.
