Overall, I was satisfied with the sound they produce, especially the treble is exceptional. However, the volume they produce is about the same as the factory speakers. Unfortunately, their magnets are slightly larger than those of my Fiat Punto mk1 factory speakers. Even without the magnet covers, the speaker covers cannot close properly, so I didn't end up using them. Also, one of the speakers arrived slightly scratched, but it doesn't affect its functionality in any way.
