Introduction: Easy Way to Tell If a Speaker Is Blown or Not!
This is just going to be a short instructable because of its simplicity. This only works with the speakers that have the positive and negative wires that hook into a stereo. To tell if the speaker is blown or not without taking it apart is really easy. All you have to do is take a 9 volt battery and touch it to the wires. If it makes scratching noises its good. If it makes no sound at all its blown.
