So, a funny title, maybe. This is a condition that we (the electronics trade) are finding more and more with a certain area of the world manufacturing. There are a lot of issues with domestic speaker subs. After the amp boards within these units are produced, the manufacturer applies a compound to the boards, a type of glue/fixative. After a while, this bakes hard like a biscuit and turns to carbon like. In turn, it starts conducting electrical current. This is not a good thing, so it kills it. Sometimes, we can pick it all off and replace the faulty components, but sometimes not.
