Do you know which car stereo part amplifies the audio signal? That part is known as an amplifier. If you try to look into your car audio system architecture, then you may find that it is somewhat confusing. Due to the complexity of its design, it can be very difficult to figure out which part of your car audio system is not working properly.

However, you can always check your car amplifier because it plays a vital role in sending signals to the speakers.

How do you Figure Out that your Car Amplifier is not Working Properly?

There are plenty of signs, which are manifested while listening to music or voice audio, that can give you a hint that your amplifier may have issues. These are listed below:

  • There is a noticeable distortion in the sound.
  • There is no sound even if you have already turned on your audio system.
  • Your stereo system starts making bizarre sounds such as farting sounds.

If you notice any of the signs mentioned above, then is important to check out your amplifier. There are chances that other components in your car audio system could also cause such distortions, but your car amplifier is usually related to these issues. Fixing car amplifier may solve issues quickly and get you up and going soon.

If you have an audio systems at your home, the stereo and amplifier are often combined. Usually your stereo doesn't blow out. Why is your home audio system work fine but many car audio system blow out so often.

The difference between a home audio system and a car audio system is have different levels of stress their under. A car audio system can have several components that may or may not work together well, made by different companies. Car owners put stereo components together in ways that may cause more stress than a system can handle.

Another reason is that car stereo systems are subject to different environmental stresses.

  • Continuous vibrations
  • Different stresses on a road
  • Temperature extremes

Your home audio system usually tested and made to work together and does not have these extreme environmental conditions. These are the reasons why your car amplifier blows out more frequently than the one you have in your home.

Now we will talk more about how you can know if the amp is blown. There are many to troubleshoot the problem. Here are some options below.

Is the Protection Mode of Your Car Amplifier on?

First of all, before assuming anything is wrong, check to see if your amp has gone into protection mode. This feature on an amplifier can help prevent damage to the amplifier and speakers. If amplifier encounters a problem, it may switch to protection mode.

This situations can occur if the speakers wires are touching each other and causing a short-circuit. Checking that the wires are properly installed can help fix this issue. If not, also check the cars charging system (battery, fuses, alternator, voltage regulator). 

Is Blue Wire Connected to Right Part of Wiring Harness?

There may be a blue wire that is being used in your audio system to access the amplifier remotely when power is turned on. If it is not connected properly to the right place, then it will fail to provide the adequate voltage to the amplifier. Therefore, you may need to check this wire and it connection. 

Do you find Loose or Blown Fuse?

Every car audio system includes the fuse to prevent damage to the audio system in case of any short circuiting. It can be placed under the hood in the power line that goes to the car cabin. So, if the fuse is blown then you wont be getting any power to the amplifier, and the amp will not turn on.

Check that the wire and fuse are connected well and replace the fuse if needed. 

Have you checked the Input of Amplifier and Output of the Amplifier?

The input of the amplifier comes from the head unit or stereo. If you aren't sure the connection is good, check to see if the audio cables are loose or have other problems.

Another solution is to disconnect the RCA cables and connect a new set to check if the cables were the problems. If the old set was connected well and didn't seem to work and the new set does work, then you've solved your problem. 

If your amplifier can now receive a signal from the stereo, then you've probably fixed the issue. However, if you only get partial signal from the stereo, and all the cables seem fine, then there may be an issue with your head unit.

But, before you blame the stereo you'll also need to check cables going from the amp to the speakers and see if all the connections are good, possibly replacing any cables that seem to have issues.

If everything seems to work good, but the speaker is not responding to the signal, try disconnecting the speaker that doesn't work and connect the cable to another speaker. This will let you know if the speaker might have an issue. So, if the speaker is bad, then replacing it with a new speaker can solve your problem.

The Amplifier is Blown

If all else seems to be intact and working fine, then we need to come back to the amplifier and determine if is blown. As mentioned above the amplifier can cause the speakers to make strange noises. This can be an indicator of a problem as well as excessive heat, smoke, or a burning smell.

Replacing the amplifier is needed if it has over heated and burned any of the parts inside. (See Video Above) You could try taking the amp out of the car and opening it. Use gloves and try not to touch any electrical components.

If you feel you still feel you have a good amplifier, you can ask a car stereo professional to make check your amp, and give you more information about what might be wrong. 

What are the known Benefits of Car Amplifiers and Subwoofers?

If you've ever been immersed in music, like when you go to the movies, you will certainly understanding the benefits of car amplifiers and subwoofers mentioned below. If you do not have an amplifier and subwoofers installed in your car audio system, then think about these qualities they can offer:

  • Enhanced audio quality
  • Higher volume
  • Good speaker power efficiency
  • Great design and organization
  • An immersive experience

In a nutshell,

Every car stereo system includes the stereo and speakers, but only some have a separate amplifier. If your wondering about the audio quality of your system, there are a couple ways to enhance it. You can get a new stereo, new speakers, or add an amplifier. 

So, when you encounter what seems to be a blown amplifier, do your research on your specific amp brand and see if you can get more information about common problems that may occur with that amp. 

Most car amplifiers can bring new life to a stereo system. It plays a crucial role in powering speaker that have specific power requirements, so there will be no sound distortion. It is very important that you choose the best car amplifier for your car audio system.

There can be many other ways to figure out whether your car amplifier is blown. Hopefully you found something useful  you can use to help with your amplifier issues. Thank you!
