Speakers back of the seat

Are there speakers back of the seat if so mine don't work, tried everything. Plz help

 

There are, if you don't have one of the 'base' or 'SE' editions.
At this age of the car, they are prone to deterioration and stop working.
Two choices, some have successfully used rebuild kits, some have installed aftermarket speakers.

 

Thanks, didn't know deterioration will make the speaker stop working, my Crossfire is is 2004
