You have to hear it to believe it. Pioneer introduces a new generation of Class D amplified subwoofers with integrated digital bass control. This unique feature generates two selectable bass modes: deep and dynamic, providing a powerful 200 watts of rich, deep bass that you can feel without sacrificing trunk space. You can easily and directly control and adjust the two bass modes using the included remote control. Thanks to the integration of Class D technology, the Pioneer TS-WX70DA is even easier to install, as it handles both high (speaker line input) and low (RCA line input) signal inputs.
