Sooner or later, every car audio system experiences a malfunction of some kind. It could be the result of something fairly trivial like a loose ground wire. Or it could be something more serious like a blown car speaker. You have two options at this point. You could also have a look into upgrading your car’s sound system and get a brand-new speaker. When it comes to speakers, yea I bought the first one on this list for my uber driver lol. He was mentioning how he couldn’t play music for his passengers, as his speaker was faulty, so I thought I’d do my part and get him a Bluetooth speaker.
But why just do this? Why not go all the way and get a subwoofer too? It’s a great combination and it’ll give you the best audio sound! Check it out here for more information.
If you think you’ve got a blown car speaker on your hands, look for the following tell-tale signs when diagnosing the problem. 
Distortion at Moderate Volumes
The unmistakable hiss or “fuzz” that comes from a partially blown speaker is tough to miss once you know what to listen for. It should be fairly obvious that something is amiss if increasing volume leads to ever greater levels of distortion from your car speakers. Fuzzy speakers are usually the result of damaged or loose voice coils. 
System Range Is Incomplete
Bad speakers under-perform for a variety of reasons. Unless the voice coil has become detached from the cone, you’ll still get some audio though it will be incomplete. For instance, a lack of high frequencies or bass is a surefire sign that your speakers are at least partially blown and need to be looked at. 
There’s No Vibration
As we all know, speakers create sound through vibration. If you touch the front of your speakers and don’t feel any vibration, the cone isn’t receiving any power. This could be the result of a wiring problem or a malfunctioning component farther back. In either case, you’ll need to crack your speakers open to solve the problem. 
Audible Rattling and Popping
Besides classic fuzz and distortion, there are other clear-cut audible signals that point to major problems. For instance, nothing but rattling coming from your woofers indicates a fully blown speaker. Likewise, a popping sound generally means that your tweeters are finished. Fortunately, these problems can be easily fixed if you know what you’re doing.
Impedance Is Infinite
One of the easiest ways to diagnose a speaker’s performance issues is by testing out it’s electrical response. With a standard multi-meter, you can quickly determine whether or not your voice coil or cone is busted. If your speaker is completely blown, observed impedance will be essentially infinite. 
Blown Speaker Damage Control
When audio system problems occur, many automatically assume the worst. The truth is that these issues can be fixed rather easily. If you observe any of the mentioned symptoms, consult Joe’s Stereo for an assessment. We’ll quickly tell you what’s wrong with your speakers and how we can help.
