They have been installed on the front doors, their bass is not something amazing but they play cleanly with nice highs, the only negative is their quality (Chinese made), if they are forced a little during the installation of the terminals, the bases that are connected to the cable start to move, and the Crossover requires a lot of attention in tightening the cables because it can be damaged.

I have installed them in my car for over four months, driven only by a Pioneer 15-year-old with the Loudness bass boost system activated, and both the woofer and the tweeter play flawlessly as long as you have a good audio source, either from the radio or from a CD, to achieve the appropriate performance. I am satisfied, as long as they withstand the test of time.

Very good and powerful speakers especially for someone who doesn't want to use a subwoofer. With support from a good source and amplifier, they are killer.
edit after a few months of use -1 star because the tweeters have started buzzing.

While their bass kills it, the tweeters of the set never played, one scratched it lightly, the other scratched it in general until it burned after two months. It is a powerful set, just make sure everything is okay before closing the deal
