You’ll probably know pretty quickly if you’ve got a blown speaker, simply from the sound. It will come out distorted and crackly as it tries to produce sound through broken equipment. There’s also a chance that you might smell something burning. Don’t worry, your speaker isn’t going to catch on fire, but a common cause of a blown speaker is overheating, which can cause a burnt smell. In either case, bring your car in and we’ll make sure to replace or, if we can, repair any blown or damaged speakers you’ve got.
