For an improved sound quality in your car, we already recommended and advised the selecting process of subwoofer, speakers head unit, amp etc for your car. Also there are a lot of topics about how to improve high frequency sound and low frequency sound. We’ve tried to cover them too. So all our hard work to let you experience the best sound quality you desire using your preferable setup in the car.
Yet, we never discussed the condition you may face due to using a high quality sound system inside the car. The most common one is the vibration that happens due to the heavy bass of the subwoofer. So, no way can you sacrifice your comfortance in a car due to installing a better sound system. Let’s find out the methods of how to stop vibration from subwoofer in car.

How to Understand The VIbration Coming from Subwoofer
First of all, the vibration mostly comes from behind the car because most of us keep the subwoofer either under the seat or behind the seat in the trunk area. But you will understand the vibration is not the vibration of a usual driving and the vibration comes while you are listening to music. So, first of all check
- Try to stop the car in a less traffic place and feel if there is any vibration happening while listening to music.
- Play a deep bass song, look at the mirror inside your car, if you find it shaking, it means vibration is coming from the subwoofer.
- Finally while listening to music, go close to the car body where you kept the subwoofer. If the body shakes even lightly or any vibration happens, then definitely the vibration is coming from the subwoofer.
Ways to Stop Vibration from Subwoofer in Car
Some of us used to believe that bass means vibration wherever you put the subwoofer. But after working with sound systems in cars for many years, now we know even heavy basses have no tendency to generate vibration if we do an excellent job in tuning the high-pass and low pass crossover for car subwoofers.
Basically, a high quality amplifier provides the option to tune both speakers and subwoofer sound. So our first job is to know how to eliminate distortion from your car audio. And to do that, we already discussed gain, volume adjustment, equalizer adjustment process. So to avoid vibration, first of all you must try your best to avoid distortion.
Now crossovers are crucial too, if you can’t set a low pass filter perfectly for your sub, the subwoofer may try to produce sound from higher frequencies that this subwoofer is not supposed to do. That unwanted frequency may play a reason to vibrate in the car.There are a few other ways to choose how to stop vibration from subwoofer in car.
Sealing off Car from Inside Using Dynamat
Soundproofing is a must when you have a heavy bass subwoofer and most of the time you listen to music on a high volume in the car. Nothing is more popular than Dynamat. You can attach it all over the car’s inside body and keep it under the subwoofer or in the trunk, so the vibration gets generated from the subwoofer, making sure it can’t pass through the car’s body.
Using Sealed or Ported Subwoofer Box
The idea of using a sealed subwoofer box is mostly for those people, who want to have deep bass sound from their subwoofer. In a sealed box, the vibration of the subwoofer gets eliminated and it helps to generate more deep bass, and in a ported subwoofer, it doesn’t necessarily stop vibration, but reduces it and improves the bass sound.
Other Things to Keep in Mind
If it were only the vibration coming from the subwoofer, we think most of us wouldn’t complain, but sometimes the vibration really bothers and it doesn’t only occur due to the subwoofer vibration. The spare tire in the trunk sometimes causes more vibration when it is close to the vibrated subwoofer. So mount the subwoofer and spare tire perfectly, so they can’t shake a bit. Also you can use foam or blanket in the trunk under the subwoofer to eliminate vibration coming from the subwoofer in the car.
FAQ
1. What are the reasons behind subwoofer vibration in cars?
– Mostly the lack of perfect tuning, very poor placement of the subwoofer and no use of vibration dampening material cause the vibration in the car.
2. How do I stop my subwoofer from rumbling?
– Firstly, ensure the subwoofer is not directly sitting on the car’s body, if you can let it sit over a foam or blanket and mount the subwoofer tight.
Final Words
Don’t think your subwoofer is almost dying because of the vibration, we can do things we’ve described here to eliminate the vibration, but before that don’t forget to tune the subwoofer. Who knows! Maybe the improper tuning may be causing the vibration.
