What happens when an amp blows??


Recommended Posts

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.

Any time you have have a power wire next to your frame put some rubber hosing (or cut up an innertube) around it. The wire is bound to wiggle (due to driving or flex) and the casing will eventually wear through.

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
