Blown Amp Symptoms

As we have mentioned earlier, it should not be too difficult to determine a blown amp problem once you have the symptoms identified. There are a few things to look for such as overheating, a burning smell, power loss, and a distorted sound. The fixes you can try depend on the actual symptom or cause of the problem.

First of all, you may wonder why your amp has even blown. For the most part, it could be a faulty amp to begin with. In this case, the only thing to do is to purchase a replacement. You can have a professional replace it for you.

But in a few instances, a blown amp could be a sign that the fuse is faulty. There may also be a short circuit that has happened. This is the case with loose connections or when the wiring is poorly installed.

Another thing to think about is overheating. When you notice that the audio system is starting to heat up faster and a bit more than it should, it could be a problem. What this means is that your ventilation is not ample and there is way too much power entering into your amp. Thus, you need to be very careful and have this issue remedied sooner than later.

Once you have a brand new amp installed, you may be too eager to test it out. However, if you put more power than it needs, it may result in blowing up. So, once it has actually blown up, it is always good to get your ventilation and cooling systems checked to avoid further issues.

But prior to fixing anything, you need to be perfectly sure that your amp is indeed blown. Here are some symptoms to look into, so you can deal with the issue more appropriately.

1. The stereo does not turn on

Obviously, if you have a blown amp, you will have a problem with getting your stereo to work. So, if the amp is not working, that does not mean you have to replace it right away. You can start by checking certain components, such as if the wiring is all good and connected properly.

You also may want to check your fuses. Perhaps they are blown, so it should be a relatively easy fix to get your fuses replaced. After checking, you can proceed to replacing the faulty parts and testing once more if your amp works this time.

2. Protect mode light is illuminated

Next up, you can check if you have the protect mode light turned on. This is a protective component that prevents internal parts from getting damaged. So, if you notice the light is illuminated, you can very much guarantee that there is a problem with your cable, speaker, or the amp.

Now, if you try to unplug your speaker wire, yet the protect mode light goes off, it means one or both of your speakers may be the culprit. This is why it is not always a necessity to replace your amp since there are other components that may be the problem. 

3. Your fuses tend to blow without any apparent reason

There is a possibility that your fuse just seems to blow, and yet there seems to be no clear reason. So, if this happens, you need to get this problem fixed sooner than later. There are many causes behind a blown fuse such as a faulty speaker or overheating. 

Amp fuses come in three types, so it is good to determine which one is the issue. This is important in determining what step you should take next. There are also some amplifiers with an internal fuse. This has a tendency to blow just to prevent massive damage. But at the same time, there may be an inline fuse present when you had your amp installed by a professional. 

So, it is good to check which fuse is the problem.

4. Distorted audio

Do you notice that the audio appears to be distorted? Perhaps you hear a buzzing noise, whining or humming sound while playing something in your stereo. If so, your amp may be blown. This is because blown car amps tend to produce a distorted sound – or it could also be a case or poor installation.

Either way, you should get your amp checked to determine if it is indeed a problem. You may also notice a fading out and in of the audio, or in some instances, a power loss may happen. Therefore, be sure to check these signs first.

5. Burning smell

When your amp tends to produce a burning smell, it may very well be a blown amp symptom. Normally, you are not supposed to be smelling anything that seems to be a burning odor. So, if this happens, it is a good idea to check if the amp is responsible for this burning smell.

6. Overheating

Lastly, when you notice that the amp is overheated, it could be due to a damaged ground linkage. Perhaps there is a short in the power connections, which then causes an overheating problem. So, it is good to check what may be causing any overheat with the system that can be impacting your amp.
