If you’re experiencing a rattling noise from your trunk when the subwoofer is cranked up, don’t worry – you’re not alone!
This is a common problem with many vehicles. In this blog post, we will discuss some of the causes of the rattle and how to fix it. Keep reading for more information!
Why Car Subwoofers Vibrate and Rattle?
There are a few different reasons why your car subwoofer might be rattling.
One common cause is that the enclosure (or box) is not properly sealed. This can allow air to escape, which causes the woofer to vibrate and rattle.
Another possibility is that the screws or bolts holding the enclosure together are loose, which can also lead to vibration and rattling.
Finally, if the speaker wire isn’t properly secured, it can move around and cause noise as well.
How to Fix a Rattling Car Subwoofer?
There are a few different ways to fix a car subwoofer that’s rattling. Before starting the fix, you must find the culprit behind the issue. So, start with finding the source of noise-
Find the Source of Noise
Finding the source can be frustrating as there is a very good chance that the issue is not that big the sound is irritating. So, there might be a tiny bit of loose bolt, a small portion of the enclosure is not sealed off, or there is something going on in the background.
So, have a close look at the subs and enclosures by cranking up the sub sound to an absolute high. This will allow you to find the issue easier but may require ear protection.
Once you’ve found the source, it’s time to fix it!
Sealing Enclosure
One common cause of rattling is an unsealed enclosure. This can be fixed by using some weatherstripping or caulk around the seams of the box. Make sure to use a sealant that will withstand heat and moisture.
And make sure not to overuse sealants as applying sealants on the cones mistakenly can cause the sound quality to drop significantly. And it’s very hard to deal with this kind of issue as the cone is a very delicate thing to work on.
Securing Speaker Wire
Another common cause for rattle is speaker wire that isn’t secured properly. You can fix this by using some zip ties or velcro to keep the wire in place.
While this is not a common cause, it happens sometimes. And it’s safe to have all your wires managed. So, consider doing this.
Tightening Screws and Bolts
If the screws or bolts holding your enclosure together are loose, simply tighten them down with a screwdriver or wrench. Be careful not to over-tighten as this can strip the threads.
In almost all cases, loose screws and bolts cause the rattling. So, you may consider using a rubber washer so that the subwoofer doesn’t get loose often.
Lower Volume
If all else fails, you can try lowering the volume of your subwoofer. This won’t fix the rattling issue but it will make it less noticeable.
Plus, if the subwoofer is rattling at a high volume only, then this will help solve the issue without doing any troubleshooting.
Lower Bass Frequency
Finally, you can try to lower the bass frequency of your subwoofer. This will help to reduce the amount of vibration and rattling.
You can do this by adjusting the settings on your amplifier or head unit.
Use a Sound Deadener
If you want to have the best sound experience, I recommend you consider buying a good quality sound dampener for your car. This will help to reduce noise and improve the overall sound quality.
Conclusion
There are a few different ways to fix a car subwoofer that’s rattling. Start by finding the source of noise and then try one of the methods mentioned above.
If all else fails, you can lower the volume or bass frequency of your subwoofer.
