The subwoofer is hinged so that it will swing to the side when the ski bag is used. A magnet on the subwoofer cover will hold the subwoofer in place against the rear bulkhead while the ski bag is being used.

The subwoofer will continue to function in either position closed/open. As mentioned, with the Harman/Karden system, the stereophonic sound is modified when the top is lowered. The sound system amplifier receives a signal from the rear window defroster relay when the top is lowered to switch the stereophonic sound off.
