I owned these in my car for about 2 years and took them out when I sold that vehicle. They couldn't be used in my new vehicle so I sold them to a fellow worker. He couldn't be happier he enjoys them. I also boutht the 52.9i Kappas as well but they weren't very worthy. The 52.9i speakers didn't last. At 1st my passenger speaker started to rattle and ting after about 7 or 9 months. Then after about a year the drivers side did the same. I left them in since I was able to raise the + on my sub amp in order not to turn the front set of speaker up to that area that they started to rattle. Even if they did you couldn't hear it in my coupe any ways since the punch was so loud. So, these are worth the price but what ever I paid for the 5.25 siblings was to much and that is that.
These speakers deliver qualitiy sound. They are very clear and have a crisp sound.
