How To Keep The Subwoofer Box From Sliding? (4 Methods)

When you have a powerful subwoofer, it’s important to make sure that the box it’s in doesn’t move around. This can damage the speaker and also make it difficult to hear the low frequencies.

A lot of people don’t think about this issue until it’s too late, and their subwoofer is sliding all over the place.

We’re going to show you a few ways to keep your subwoofer box from sliding. By following these tips, you’ll be able to protect your investment and ensure that you get the best possible sound from your speaker.

Why Do Subwoofer Boxes Slide?

Why Do Subwoofer Boxes Slide

The first question you might be asking is, “Why do subwoofer boxes slide in the first place?”¬†There are a few reasons for this. First of all, subwoofers are usually heavy. This means that they can create a lot of force when they’re turned on. This force can cause the box to slide, especially if it’s not securely fastened down.

Another reason for sliding is that subwoofer boxes are usually placed on hard surfaces. This can create a lot of friction, which can cause the box to move.

Finally, subwoofers create vibrations. These vibrations can cause the box to shake, which can also lead to sliding.

4 Methods To Keep Your Subwoofer Box From Sliding

1. Mats

The simplest method is to lay a specific mat that will stop heavy enclosure side motions on the trunk floor. Along with carpets and rubber backing, these mats are available at any automobile store or internet retailer.

You put it in your trunk and start your car. Now that it has a solid base to rest on, your subwoofer is much less likely to move around when vibrating.

Mats not only prevent the subwoofer from moving but serve as a cushion between the subwoofer and the trunk floor, which lessens car rattling and vibrations.

2. Wood Pieces

If you don’t want to spend any money, another method is to use wood. This can be anything from small pieces of trim to large sheets of plywood.

You can either screw or glue the wood to your trunk floor. This will provide a solid base for your subwoofer box and keep it from sliding around.

One advantage of using wood is that you can customize the size and shape to fit your trunk perfectly. This can help to minimize vibrations and rattles.

Another advantage is that you can easily remove the wood when you don’t need it. This is helpful if you need to use your trunk for other things, such as carrying luggage.

3. Velcro Straps

Subwoofer boxes can be kept from sliding with Velcro straps. You can buy Velcro straps at any hardware store. It prohibits drilling holes or installing metal plates since they make the car look amateurish and lower its worth. Velcro also eliminates the inconvenience of having to remove screws in order to move your sub box in and out of the trunk.

Step 1: To access the subwoofer enclosure, open the trunk. Turn the enclosure over to reveal the side of the box’s bottom that faces the trunk.

Step 2: Measure the straps to the appropriate length, using the side of the box as a guide. The straps should be long enough to reach from one side of the box to the other, with a few inches of extra strap on each end.

Step 3: Cut the straps to size with a pair of scissors.

Step 4: The Velcro straps should be carefully positioned up from corner to corner on all four sides of the bottom of the box after removing the sticky backing.

Step 5: Now position the subwoofer enclosure in the trunk where you wish to secure it, set it down, and lightly press. Because it will adhere to the carpet on the floor, the Velcro affixed on the bottom of the subwoofer in the trunk will be securely mounted.

4. Tape

You can also use tape to keep your subwoofer box from sliding. This is a cheap and easy method, but it’s not as effective as other methods.

Duct tape, electrical tape, or any other type of strong tape can be used. Just make sure that the tape is sticky enough to hold the box in place. You can also use multiple layers of tape to increase the strength. Keep in mind that you don’t use it so much that it’s difficult to remove the box when you need to.

There are a few things to ponder when using this method.

  • First, the tape can damage your trunk if it’s not removed carefully.
  • Second, the heat from your car can cause the tape to loosen over time.


Subwoofers are a great way to improve the sound of your car stereo. However, they can be difficult to keep in place. There are a few different ways that you can keep your subwoofer box from sliding, including Velcro straps, tape, and bungee cords. Ultimately, the best method depends on your specific situation. Experiment with different methods until you find the one that works best for you.
