Great midrange speakers

I'm a big fan of infinity kappa speakers and these do not disappoint. Price is good and build quality is excellent. I have these powered off my receiver and they are louder than I expected. Bright and very musical but I ended up turning them down a bit. These are meant to be added to a infinity 2 way component set because they have a plug that plugs into the crossover. You just need to cut one end off and you can use them as is. I installed them in a 2016 jeep compass and it was very easy. They fit perfectly in the middle air vents. No cutting, sanding, or grinding at all. Fit perfectly in with the grills. I even just used the hardware that was included. Kappa 6x9 front doors with reference series 6x9 rear doors. Sounds better than any premium factory system I've heard. Check out the pictures, infinity badge came from 6x9s
