These are a great set of components for a low price. I installed these in my 07 Mercury Mountaineer to replace the front 5x7s with custom brackets. Currently im just running them off the factory stereo system, and they are much more clear and crisp then the factory speakers. They pick up so much more of the music, the bass is good and the tweeters have a very natural/mellow tone. Not a harsh, high pitched tone that some component sets have. The crossover is small and compact and fits neatly behind my door panel and the tweeters blend right in with the interior. Over all I'm happy with them but i plan to amplify them soon with a new head unit and a Rockford amp. If your looking for a set of components that you could run off your head unit, these would be fine, they don't seem to mind the low wattage, but to really get the full JL experience, spend the extra 150-300 dollar and put a amp on them. They will blow your mind for the price!
