The speakers are probably blown from playing music too loud. The speakers in that car are small.

All your car all of your cars components run off a fiber optic loop and in this series of fiber optic components there is an amp called a logic 7 amp in the trunk of your vehicle you need to purchase a fiber optic jumper loop and work your way through the components to figure out which one of them is faulty but more than likely it's the logic 7 and if it isn't one of those things then it is the ask unit which is in your dash that runs everything concerning music or audio which is the unit that is your CD player.. when you use the fiber optic jumper loop you take the jumper cable out of the the device that you're going to check for a signal when you hook up the fiber optic jumper loop it should show a red light coming out the other side of it on one of the cable ports if it does not show that it is either that unit that is faulty or the one just before that so you just have to check them all and work your way around him to figure out which one of them is wrong or not working correctly and you can use that jumper loop to bypass that whole unit all together and get your sound back
