How to know if my car speaker is blown?
The most frustrating thing about any car stereo system is when the car speaker is blown. The problem is that it is very difficult to repair a speaker. Even when you spend money on repairing it, the quality of sound it produces will never be quite the same.
A blown speaker will impact on the entire stereo system. It does not matter whether you have state of the art automotive stereo system or whether you have the average stereo system, a blown car speaker can drastically reduce the performance of the entire automotive stereo system.
The main problem is that many people are not able to detect a blown car speaker. We will share with you a few guidelines which you have to follow in order to tell if your speak has blown.
- Listening to the speaker output:
A blown speaker can be one of two types. These are:
- Partially blown speaker: Partially blown speaker is actually difficult to detect. It will produce some sound but it will have a hissing sound as well. This is the reason why you have to listen carefully to the speaker output. Only then will you be able to determine whether the speaker is partially blown or not.
Another way to detect the partially blown speaker is to play audio at full volume. At moderate levels, it might be able to produce audio. At higher levels, there is plenty of distortion if it is blown out. As a result, it will become easier for you to detect the partially blown speaker.
- Fully blown speaker: On the other hand, when it comes to a fully blown speaker, there is no problem detecting it. It will not produce any kind of output!
All you need to do is to try playing different frequencies and listening to the output of the car speakers. If the sound is reproduced properly at all frequencies, it will be easier for you to detect the fault. This test will not take more than 5 to 7 minutes of your time.
- Checking the surface of the car speaker:
Vibration is pretty common on the surface of the car speaker. This is especially true when you choose speakers like woofers. As a result, when you turn up the volume of the speaker, the surface of the speaker actually vibrates. This is one of the easiest ways to detect a blown car speaker. You have to just place your hand over the car speaker. Even at a higher volume, if there is no vibration, it indicates that the car speaker is blown.
The only downside to this particular test is that it works on larger speakers only. If the speaker which you are testing is smaller in size, it will not work accurately. In such cases, you will have to use the other 2 tests we have mentioned.
- Isolating the affected speaker:
You can use the fader system in order to isolate the different speakers. Once you are able to isolate a particular speaker and play the audio, it will be easier for you to detect the blown out speaker. You will also be able to easily detect whether it is partially blown or whether it is fully blown. In either case, you will have to think about replacing this car speaker.
In case you don’t have the fader system in your automotive stereo system, you will have to physically disconnect the speakers in order to test them. This will require the services of experts from auto service as you will not be able to physically disconnect and reconnect the wires by yourself.
So, if you are confused as to whether the automotive speaker has blown out or not, these are the 3 tests you can conduct. With the help of these, it will become easier for you to detect any fault in the stereo system. Once you are able to diagnose the fault, it will become easier for you to replace it. Continuing with a blown out car speaker system can degrade the performance of your automotive stereo as well.
