ISSUE
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.
ACTION
Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
The vehicle is equipped with two (2) subwoofer amplifiers which are located next to each other under the driver's side kick panel.
Swap the upper and lower connectors, from one amplifier to the other, and confirm that the crackle follows the amplifier to isolate the bad part. (Figure

Replace the suspect amplifier per Workshop Manual, Section 415-00. If static cannot be isolated then continue with normal diagnostics per Workshop
