Can subwoofers damage your car?
This is a question I get asked often and what I always say is, “Yes.” Subwoofers can potentially damage the car. Subwoofers are strong enough to potentially cause some parts in your car to become loose, but they will not cause any structural or mechanical damage. Some examples of things subwoofers will loosen are rearview mirrors, door panels and the nuts holding them to the car.
Subwoofer in your Car: How Do Subs Affect It?
Subwoofers May Cause a Car Battery to Drain
The most common way a subwoofer can damage your car is by draining the battery. You’re adding extra strain to your electrical system when you put a subwoofer in your car. Sound vibrations take a lot of power to produce. The power required to run a subwoofer draws from your battery.
The most significant issue is the constant power drain. When you play your subwoofers when the car engine is off, the battery will drain faster. This is due to the fact that batteries only charge when the engine is running. Many car batteries can be killed by just one subwoofer.
Even if the car’s engine is attempting to keep the battery charged, you might be drawing too much electricity from the electrical system, which can drain the battery even while it’s running. This is why if you replace your subwoofer you should install a second battery or replace the alternator.
Subwoofers Can Cause Your Car to Rattle
Subwoofers can cause parts of your car to rattle and shake. The sound waves transmitted from these subwoofers turn into air molecules, causing some parts of your car to vibrate. This is an especially common problem for people who have older vehicles with fewer interior soundproofing components or materials that absorb the noise better. It is important to note that rattling in cars is caused by low-frequency sound waves, not subwoofers themselves. There are certain types of parts that are more prone to rattle when the car moves.
Vibrations from the Subwoofer May Cause Car Parts to Become Loose
Subwoofers are designed to emit low-frequency sounds in order to produce heavy bass. The bass created by these subs can be enough to vibrate the car panels and hardware. The body panels are stressed by the resonance. Because of resonant frequencies, the vehicle’s body panels are being transformed into speaker components, and all of the little plastic tabs and mounting bolts for those areas are vibrated. Over time, screws and bolts that hold the car parts will become loose because of vibration. The vibration of the subwoofer creates more opportunities for loose screws and bolts to become even looser, or completely come off. This issue will usually occur on both older and newer vehicles.
Newer cars have had time to develop technology designed to specifically combat this problem, but owners of older models may not be aware that their car could be affected by the vibrations.
Is it possible to harm your alternator by using subwoofers?
Subwoofers don’t have the ability to damage your alternator on their own. However, if a subwoofer and its amplifier draw too much power from your battery, they can cause harm to your alternator. This might lead to overheat and can potentially destroy the alternator.
How to Ensure That Your Subwoofer Does Not Damage Car: Soundproof!
When you fit a subwoofer in your car, it’s important to install soundproofing mats. They reduce vibration and ensure the overall quality of your music system is not compromised.
Soundproofing mats are also known as sound deadening materials and they come in a variety of types. Sound dampening mats are made of thermal or acoustic foam and are mainly used to reduce noise, vibration and echoes.
Soundproofing mats come with adhesive backing so they are easy to attach to any surface. Once you’ve determined what part of your car you need to soundproof, just peel off the protective layer and stick it down firmly. If necessary apply heat by using a hair dryer then press it into place exactly how you want
Is it true that subwoofers can break car windows?
A common question asked by many a car owner is can the sound from my subs break or shatter my windows? The answer to this question is yes. There are several factors to take into consideration when deciding whether or not your subwoofer can actually cause your car windows to shatter.
The first factor is the proximity of the car window to the subwoofer. The closer and more parallel the surface where you are projecting sound from, be it a wall, floor or ceiling, will speak directly to its ability to vibrate small objects in close proximity to its point of impact. This is why when you stand next to a speaker at a concert, the sound hits your chest like a ton of bricks.
The second factor is the decibel level. In order for something to shatter, it has to be under immense pressure and that pressure has to be applied very rapidly. Decibels work on the principles of being logarithmic, measured by tenfold. So if you increase the decibel level by 100%, you are actually doubling the amount of pressure that is applied to whatever it is that’s projecting the sound waves from your subwoofer. Most cars on the market can handle a few extra decibels of pressure that your subs will project in comparison to any system you would find in someone’s home.
The third and final factor is the type of car window that you have. Some cars on the market have factory installed tinted windows, which factor in to how much pressure will be applied and whether or not they can shatter if exposed to high decibel levels for extended periods of time.
Subwoofers can potentially damage the car and loosen some of its parts, but they will not cause any structural or mechanical damage. There are no negative consequences of having a subwoofer in your car other than draining the battery every once in awhile and possibly loosening some of the parts. Some examples of things subwoofers might loosen are rearview mirrors, door panels and the nuts holding them on to the car.
