I have a 2006 GS300 and for some reason theres no sound coming out when I turn on the radio or put in a CD ? Everything works I just cant hear any sound.. Dont know much about stereo this kind of stuff so pls help !

 

Probably the amp. it located in the floor on the right side of the trunk. see if you can get a known good amp to test it

 

Alright will do. Also when I turn the **** to turn the volume up or down, it doesnt show up on the screen that im turning it. Its as if its not getting the connection or something. Even when I press the volume buttons on the wheel nothing happens
