Installed in my f-150. I downgraded to these from the equivalent kappas because of the giant kappas tweeters. The reference tweeters are more conventional in appearance although I had to spray paint their mounts to black from the original silver to match my interior. Installation was easy and the sound performance is solid. The mid bass doesn't hit as hard nor is it as full as the kappas. So, if you can handle the look of the kappa tweeter and the increase in price I would opt for the nicer kappas. The silver hockey puck sized tweeters were too much for me.
