    Help with Alpine SWR-12D4

    I have alpine type r 12 inch subwoofer in sealed box. Before it was in ported box but the bass was too muddy and overpowered songs so i changed it to sealed and now it souns clearer. The problem is that it doesnt play the bass that is in the background in songs. I dont know how to explain it...
