Principles of Operation: Subwoofer

WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

With the Premium sound system, the subwoofer and amplifier are integral. The enable/clip detection circuit carries out 2 functions: to turn the amplifier on, and to indicate to the ACM  when the subwoofer output distortion signal reaches a damaging level. The ACM  then clips the audio output signal to prevent damage to the subwoofer.
