It sounds awesome. I just sold my mb quart and bout some boston acoustic pros components and returned it because I tought it was too expensive. I had no speaker so I decided to put the bose in. I couldn't believe it sounded bettter than the mb quart almost as good as the BA. It has SO MUCH mid bass. It maybe because I put dynamat in the door panel. I'm running it with an alpine mrv-f407 4 channel amp. I don't have to buy speakers no more.
