What happens when an amp blows??

8 posts in this topic

What physically happens to an amp when it blows say from... Voltage drop/high voltage? Too low of impedance? Thermal? Or something else?

I have always wondered which parts fail and what causes them to fail in a given situation

Short answer: Magic smoke appears.

Long answer: Lots of thermal induced electromigration (arc welding) in whatever part gives up the smoke first.

Mosfets are very common. Otherwise I've seen power supplies roasted off the circuitboard.

when my 1800 watt kenwood went out the first time, a soldered piece just blew off

re-soldered and was totally fine

2nd time it blew, there was a scorch mark of about 1 square inch

when my 5,500 power acoustik gothic series blew, 1/2 the heat displacement was blackened
