So here i will explain how to diagnose if it is the amplifier or something else went wrong. This amplifier controls all the speakers on the car, so if it goes bad you will not hear any sound in any speaker.īut not always amplifier is the problem, in some cases other modules go bad, interrupting MOST network and you will not hear any sound even with working amplifier.
