The speaker, which is supposed to be compatible with a Renault Scenic 2, is not. At least not without modifying the speaker and cutting the door.
It's a shame for a product that's supposed to be compatible.
Beyond that, it's not transcendent, the frequency response is ok, but you still get a strong feeling that it's lacking in the low frequencies, even after running it in. If your car radio doesn't allow audio processing, I'd say this isn't a good solution.
Otherwise, this is a decent speaker for the price.
