Mobile Suites "entertainment system" woofer question

The on/off switch only turns on/off the power to the subwoofer. You also need to select the subwoofer in your entertainment systems settings. This is normally done through onscreen menus. On some systems you need to select surround sound to enable all speakers, on others you'll individually select which speakers you want on or off. This varies from one system to another so you'll have to scroll through your settings unless someone here has the identical system.
