Luggage Compartment Subwoofer Amplifier
WARNING: This page is about a different car, the 2013 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.
The 4 channel non-networked luggage compartment subwoofer amplifier is found on Shaker Pro-equipped vehicles. Audio signals are sent from the ACM to the luggage compartment subwoofer amplifier. These signals are amplified and sent to the 10-inch (254 mm) luggage compartment subwoofer enclosure. Only 2 of the 4 channels are utilized, and are bridged for higher power output to the subwoofer.
