How to tell if a Subwoofer is Blown

Hey Guys…

Do you think your sound system is wrecked? Do you want to know if your Subwoofer is blown or not? Here, this posts shows clearly if your Subwoofer is blown!

First off, make sure it is wired up correctly to your car and try the sound! Still nothing? Try it in another car and see if it works… Still no? Watch this video to see if your Subwoofer is blown!

If you have a very strong bass, which is wound up very loud, and assuming that the amplifier is NOT clipping, the speaker can blow simply because the cone/suspension/voicecoil fracture or otherwise separate. Suspension failure tends to me the most common – the cone tries to exit from the speaker due to excessive movement, and the suspension fractures around the extreme edge of the speaker itself – most are foam-rubber these days, but very old subs could still use corrugations.

This allows the speaker cone to move forward excessively, carrying with it, the voicecoil and former. These essentially then “Pop” out of the magnet, destroying the voicecoil connections in the process. This is what you MIGHT have heard as “Popping” a speaker.
