Some 2008-2009 Mustang vehicles equipped with front door sub-woofers and built before 7/7/2008 may exhibit static, crackle, pop or distorted sound from the front door sub-woofer.
Follow the Service Procedure steps to correct the condition.
The vehicle is equipped with two (2) subwoofer amplifiers which are located next to each other under the driver's side kick panel.
