Are Subwoofers Bad For Your Car? Know Soon To Fix
When considering an upgrade to their car sound system, most individuals choose subwoofers as one of the essential parts.
This is not surprising given that subwoofers enable you to create the greatest audio experience possible in your vehicle. Because they create clear and rich tones, subwoofers are the perfect option for automobiles.
However, some drivers crank up the volume on their subwoofers to a point that everything around them vibrates and even causes ear damage.
Many people have been left wondering what kind of harm subwoofers do to their vehicles as a result. Can subwoofers eventually harm your car in some way? And what is the best solution to solve this problem? Let’s discover it right now.
What are the subwoofers?
In reality, subwoofers are speakers or loudspeakers that produce low-pitched frequencies, specifically those between 20 Hz and 200 Hz.
Bass is a common term for such low-pitched frequencies. A subwoofer helps loudspeakers improve the low-frequency regions in their sound reproduction.
A movie’s explosions, numerous musical instruments, and ambient sound effects all produce bass, which is a very low frequency.
A subwoofer is composed of a port or enclosure, a driver, and maybe an amplifier. The enclosure is typically made of strong wood called MDF (medium-density fiberboard). The subwoofer cabinet’s port or vent is utilized to reduce distortion and unwelcome noises.
How do they work in your car?
A larger woofer/driver and an amplifier team up to generate low-pitched frequencies through the usage of subwoofers.
When your subwoofer is connected to an audio receiver. Low-frequency effects (LFE) audio signals are transmitted from the receiver to the subwoofer via electricity. A magnetic voice coil in the amplifier then processes the current and transforms it into sound.
The magnetic coil assists the cone’s vibration and generates deep or less profound sounds of the highest quality. The amount of bass a subwoofer can create is determined by its size.
A dust cap is also on the cone. This cap guard against dust particles getting into the cone and damaging it. So that the subwoofer’s performance won’t be compromised, low-pitched deep frequencies are re-created by combining these sound impulses with air.
Are Subwoofers bad for your car?
Trunks are the best spot for car subwoofers. When subwoofers are utilized loudly, vibrations from them can harm your car’s interior components.
The engine of your car and anything else nearby won’t be harmed by the subwoofer’s vibrations. However, it might also have an impact on other elements or parts of your car.
Subwoofers Bad For Your Car
The battery drain caused by a subwoofer is the most frequent type of harm. Adding a subwoofer to your car puts additional demand on the electrical system.
It takes a lot of power to create sound vibrations. Your battery is used to provide the power needed to run a subwoofer. The continual power use is the main problem. The battery will discharge more quickly if you run your subwoofers with the engine off.
Batteries can only be charged when the engine is running, which explains this. A single subwoofer has the power to drain numerous automobile batteries.
The battery might be drained even when the car is operating even though the engine is working to keep it charged if you are using too much electricity from the electrical system.
For this reason, you should add a second battery or replace the alternator if you replace your sub.
Your Car May Ruttle
Resonance is a vibrational frequency that permeates every building and object. By attaining the resonance frequency point, any continuous vibration that causes another item to vibrate can be produced.
Your car’s interior can shake as a result of subwoofers. The sound of loose things vibrating or swaying against one another is referred to as rattling. Cars rattling is a result of subwoofers transmitting low-frequency sound waves.
Air molecules are created by the sound waves that subwoofers broadcast. As a result, the car’s various components tremble. This occurs most frequently in cars that aren’t soundproofed against the resonance and vibratory effects of subwoofers.
It is not necessary to install a subwoofer in a car to install a sound-deadening material. Due to resonance, the car’s body panels function as speakers.
The body of an automobile is basically a metal shell that absorbs and reflects sound waves. This makes several automotive components, especially the panels, tremble and rattle.
When an object resonates at its natural frequency, windows and other things start to vibrate. It is frequently identified as a buzzing noise that coexists with the subwoofer’s sound.
Even though there isn’t much sound pressure, the loudspeaker will nevertheless force some parts of a car to shake when it reaches the resonance frequency.
Subwoofer Vibrations Can Loosen Car Parts
Subwoofers are designed to emit low-frequency sounds in order to produce heavy bass. Increasing the volume level of the sound coming from your sub can induce vibrations in your vehicle’s surroundings, especially the panels.
These subwoofers’ bass can be powerful enough to cause the car’s panels and hardware to vibrate. The resonance puts tension on the body panels.
The vehicle’s body panels are being converted into speaker components due to resonance frequencies, which causes all of the small plastic tabs and mounting bolts for those locations to vibrate.
Vibration causes screws and bolts that keep the automotive pieces in place to loosen over time. Loose screws and bolts have more chances to get even looser or to come off entirely due to the subwoofer’s vibration.
Usually, both older and newer cars will have this problem. The body panels need to have vibration and sound dampeners installed if you’re installing several subwoofers.
These dampeners serve as components that reduce vibration and noise. The door panels absorb your subwoofers’ vibrational waves. This ensures that both bolts and nuts remain intact.
Heavy Subs Can Cause Car Rear to Sag
Car subwoofers vary in size and weight. The subwoofers come in sizes between 8 and 24 inches.
When it comes to amplifiers, the general rule held by many is that the bigger the subwoofer, the better quality sounds produced.
The majority of the time, larger subwoofers also tend to be heavier. This implies that installing a subwoofer in your car adds weight to it. Your car’s rear will sag as a result of this additional weight.
Smaller cars are typically affected by this sagging, and because of the strain placed on them, these cars must work extremely hard to move along.
Are Subwoofer Vibrations a Problem for Your Car’s Engine?
The normal operation of your car’s engine cannot be impacted by subwoofer vibrations. The engine block of the car and everything nearby is not harmed by them.
The vibrations from a subwoofer cannot harm or interfere with a car’s engine because they are too powerful. More abuse can be taken out on a car engine than a stereo system can.
The engines in cars are made to be tough and durable. They can withstand vibration and harsh environments because of this. A car engine is far more significant than a subwoofer, in actuality.
The power of an automobile engine is immense. It is so strong that it may accelerate significantly while moving your 2000–20,000 pound vehicle.
As a result, the power and vibrations produced by a subwoofer are far below the power needed to stop an engine.
Can subwoofers damage your car’s alternator?
Your alternator cannot be harmed by subwoofers alone. Subwoofers can harm your alternator if they drain too much power from your battery, together with their amplifier and the accompanying amplifier. And this could potentially damage the alternator by causing it to overheat.
The electrical systems in your car are charged using an alternator and a battery. Most subwoofers can operate flawlessly off the battery system in your automobile.
However, there are several circumstances in which your subwoofer and the amp operating it place an undue strain on your automobile battery.
Remember that in addition to your music system, there are other items that depend on the car battery for electricity. Consider that you drive a car with a 105A alternator. This indicates that the alternator on your automobile is 105A. This current must be used by all equipment and processes that depend on your car battery.
The type of sub is not the only factor to consider. The amplifier is also crucial. Power from the sub is taken and made available by the amp. To verify if your stereo system has any electrical issues, first, check the power rating of your amp.
If you install a strong audio system in your car without making the proper power changes, you could put a lot of stress on the electrical system.
You also can control the volume of such vehicles’ stereo systems by simply keeping it at a level your alternator can manage.
But the best option is typically a high-output alternator. By doing this, you can be confident that your high-performance sound system will get the power it needs without endangering the electronics of your automobile.
How to Make Sure Your Subwoofer Doesn’t Ruin Your Car?
Soundproofing mats should be installed in your car when you install a subwoofer. They ensure that the overall quality of your audio system is not impacted while reducing vibration.
There are several different kinds of soundproofing matting, commonly referred to as sound-deadening materials. Thermal or acoustic foam is used to make sound-dampening mats, which are primarily used to lessen noise, vibration, and echoes.
The adhesive backing on soundproofing mats makes it simple to stick them to any surface.
Simply peel off the protective sheet and firmly adhere it to the area of your car that needs soundproofing after determining where it has to be placed.
If required, use a hair dryer to apply heat, and then press it precisely where you want.
Is it true that subwoofers can break car windows?
Extremely loud subwoofers can break car windows, especially if the tempered glass pane is already cracked.
A few car windows have been known to break due to the violent and intense frequency at which extremely loud subwoofers vibrate.
Every glass substance, in theory, has a natural resonance frequency at which it will easily vibrate. If it is disturbed by a sound wave, it will vibrate at this rate.
The amount of vibration that is required to cause the glass to vibrate will significantly increase when the subwoofer’s output is excessively loud.
The glass breaks when this vibration rises above the allowable vibrational threshold of the material.
Although really powerful subwoofers have the potential to break automobile windows, this rarely occurs. It will also require a significant amount of power.
Therefore, you shouldn’t be too concerned about smashing your car windows unless you have several highly effective car subwoofers installed and connected to some highly effective amplifiers in your vehicle.
FAQs
Since it varies depending on your area, there is no exact answer. There may be limits on how loud your car radio may be in general in some places, where car subwoofers are prohibited if they surpass a specific decibel level. Checking with your local government to determine if there are any particular rules is advised.
Although it won’t harm the car’s structure, it could accelerate the interior and exterior panels’ “aging” due to vibration, particularly where the speaker is installed.
