Audio Systems: Mustang Mach 1000 Audio, mustang mach, radio works

Question
I have a 2003 Mustang with a Mach 1000 Audio System. The radio works but I can not get the subwoofers to work. I have checked all fuses. I do not have wiring diagrams. Any suggestions or help would be appreciated.

Answer
there are two amplifiers in the trunk
the small one is the woofer pull the gray plug  and test for power
most likely you have power there, if that is the case,bad amplifier
i replace about 10 always with water inside and my best source for them is ebay

good luck
