I have a 2010 JSW with a dead head unit. Everything worked fine until I made the mistake of changing a tail light with the car running and the radio on. The radio went dead and there was a loud pulsing sound coming through the speakers. I actually had to disconnect the battery to make it stop.
All fuses good, incuding the 15A on the back of the head unit, but the unit is completely dead.
I removed it and opened it up, no signs of anything blown and no lectrical smells (I realize that is no guarentee).
Is it possible that the head unit is fine and the external amp is blown? Does that ext amp feed pwr to the unit, or only amplify the audio.
Anyway don't know where to start.
Thanks in advance for any advice/direction.
