2011 Audi Q7
 

My passenger door speaker hasn't work in a while. I took it to Audi and they couldn't fix the problem. Today a work I took of the passenger door panel to see what's wrong. Of course still won't work. Now the drivers speaker not working. Went to the car to go to lunch and now the passenger side of the car is not working...also the windows, lock, and mirror. Please help.
