I have a pair of very slightly used infinity kappa 693.9i 3-way 6x9 speakers. These sound great, but i decided not to add rear fill in my civic. They come with crossover also, and the box. These will work with factory headunit or aftermarket. Also they have a feature to pull 2 ohms out of your amp, so you're getting the most power to them. asking $100 + shipping.
here goes more info on them http://www.crutchfield.com/S-N0hEIEF...pa-693-9i.html

 

Are these the slim ones or the deep mounts?

 

they made slim ones? these are regular size
