Help Problem with my 05 speaker

i just bought my 05 with JBL and Navi, I have a problem with my navi and phone blue tooth function. Basically all the voice from the navi and blue tooth is all go to the left front speaker "if i'm right". But i tried to test the blue tooth and the navi function, both of them have no sound "People can hear me talking but i can't hear them". I took the door panel to check if the speaker working, all i can hear from the bottom speaker is high pitch sound. just wondering is that mean my speaker located at the bottom driverside door broken? or the stock amp is not longer function? I need help by some audio expert.

 

no one? i tried to search, but nothing similar.

 

My problem has been solved. took me 3 hr to rewire all the speaker on the driver side door.
