I was skeptical whether you get for so little money really useful speaker. Now I know - yes. There are of course no High End Speaker, but they play quite harmonious without sharpness and with a clean bass - for a 13cm speaker. Built I have to be cut away in the front doors of a Renault Megane 2, thanks to the included Adpater for the tweeters, it was done quickly, but some leisure from the inner plastic splash guard in the doors so adjust the bass there. Anyone who wants to improve at a low price, with minimal technical skills, the sound in his car is really well served here.
