Car Stereo Troubleshooting – Problems & Solution
1). Stereo Has Sound But No Bass
A fundamental part of the music listening experience is being able to hear every part of it — one of those parts that are the easiest to catch if missing is the bass. If the bass in your speaker suddenly disappears, don’t worry, it will come back if you know what to do.
So ., how does this malfunction happen?
Generally, when factory speakers are being replaced or upgraded, and new speakers are installed, they can lose some critical aspects of their sound. To understand this crucial error in your speakers, you’ll need to know how the bass sound in the speakers actually functions.
For bass to be produced through your speakers, air needs to be pushed out of them at the same time. If one speaker pushes air while another pulls air, then the bass sound in the speakers will virtually disappear because the speakers themselves are out of polarity. This leaves you without the bass drop you so desperately need in your life.
The other symptom could be that you are using aftermarket speakers rather than factory speakers. Because they are heavier and harder, they actually take away a lot of the bass sound in the speakers while amplifying others. If you’re attached to the bass sound, then aftermarket speakers are probably not what you should install in your car.
However, there is an easy fix to this problem.
Make sure that the speakers are connected to the right wire. Like batteries, the + and – should line up with the corresponding side. You can also add an amplifier, which will improve the sound of the bass as well as the overall sound of your speakers.
2. My Car Radio Stopped Working Suddenly
While some of us survive on our phone’s streaming capabilities, there are still those of us out there that make use of our car radios. Another common malfunction that may happen with car speakers is the disappearance of this vital news and music source.
If you find that the radio is no longer working in your car, the cause is most likely a disconnection from the power source or where the current passes through. Alternatively, there could be a blown fuse in the system or a problem with the power or ground connector.
There are different effects on your car’s radio based on what is causing the problem. For example, if the radio won’t turn on at all, then the symptom is probably a blown a fuse or a wiring issue. If the radio turns off sporadically, then there is most certainly an issue with the ground connection.
If both the display and radio turn on and off together, then the head unit is likely not getting enough power supplied to it. If the radio turns off at moments of bumps or when taking a corner in your car, then a connector is loose.
If you want to check if a fuse is blown, which will be the most significant damage to your radio, then you will have to check to see if a reading is recorded. If there is no reading recorded, the fuse is blown. If there is a reading recorded, then there is another error affecting your radio.
3. What’s that Noise? The Unwanted Audio Intruder
This a fairly common malfunction that we see in car speakers regularly, and one of the earliest signs that something is wrong with them. Not to mention it’s aggravating to hear an unwanted sound affecting your music and not being able to stop it.
However, there are ways to fix this problem without having to get a brand-new system.
Unwanted noise is also one of the most difficult to diagnose as there are multiple issues within the system that could be causing it. Depending on what sound your speaker is emanating, you can find a way to solve this problem and get your speakers back to running properly.
If there is a whining sound coming from your speakers, then it’s probably because the amplifier or head unit’s ground were not correctly chosen. A bad connection can also cause a whine.
If you hear a popping noise coming from your speaker, then there is most likely another technical issue in another part of your car that’s causing a height in voltage, thus the popping sound. A popping sounds could also mean that the speaker is either too old, or has a bad input or connection.
4. Car Stereo Has Power But No Sound from Speakers
If the sound suddenly cuts off in your speakers, then there are a couple of factors that could be at work.
A speaker wire could be loose, or the amplifier being used could be overheated from overuse. Airflow is essential to keeping the amplifier cool and functioning.
5. An Overheated Stereo
An amplifier isn’t the only part of the sound system that can become overheated. The stereo can also overheat.
Most times , this is caused by incorrect wiring. If the stereo becomes too hot, it can be incredibly dangerous. This constitutes checking the entire sound system for wiring flaws, or perhaps replacing the whole system. Using a high-quality RCA Cable for audio connections could also help.
