How to Keep Subwoofer Box from Sliding? (Complete Solutions)

If you’ve ever had the problem of your subwoofer box sliding around in the trunk of your car, you know it can be incredibly frustrating. Despite your best attempts at using various items to wedge it in place, the box still moves, and the noise becomes unbearable.

If you’re trying to keep your subwoofer box from sliding, there are several options. Ratchet belts and straps, adhesive strips, neo-magnetic enclosures, and even l brackets can be used to secure the box and keep it from sliding.

We’ll discuss each option so you can find the one that works best for you and your car. So, let’s get started and keep that subwoofer box from sliding around!

How to Keep Subwoofer Box from Sliding

What Are the Common Causes of Subwoofer Box Sliding?

Subwoofer boxes can easily slide around when the bass frequencies vibrate, decreasing audio quality. Here are the most common causes of subwoofer box sliding:

1. Poor Installation: If the box is not properly secured to the floor or mounting surface, it can slide around as the bass frequencies vibrate.

2. Low-Quality Construction Materials: Some subwoofer boxes are made of cheap, lightweight materials that can easily be shifted when playing the bass.

3. The Subwoofer Is Not Properly Balanced: If the box is not evenly weighted, it may be more prone to sliding.

4. Uneven Or Slippery Surface: Without adequate friction, the box will slide around the trunk, even with the slightest movement.

What Kind of Surface Should the Subwoofer Box Be Placed on To Help Prevent Sliding?

The best way to keep your subwoofer box from sliding is to place it on a surface that provides a good amount of friction.

Placing a subwoofer box on a carpeted surface can help to prevent sliding due to the increased grip provided by the carpet. Non-slip mats can also provide a safe and secure base for the box. Hardwood and rubber surfaces can also be effective in preventing the box from sliding.

Make sure that whatever surface you choose is FLAT and supports the weight of the subwoofer box, and it won’t move when the bass hits.

How To Keep Subwoofer from Moving in Trunk

There are several ways to keep your subwoofer from moving in the trunk and making a ruckus. Here are the 6 best ways and how to implement them:

Ratchet Belt

  1. Start by determining the size of the ratchet belt that is needed. Measure the circumference of the subwoofer and the trunk opening, then subtract the circumference of the subwoofer from the trunk opening to get the correct size of the ratchet belt.
  2. Place the ratchet belt around the subwoofer and trunk opening. Secure the belt by threading the end of the belt through the ratchet buckle and pulling it tight.
  3. Pull the belt tight by pushing the ratchet buckle inwards and then releasing it. This will lock the belt in place, preventing the subwoofer from moving.
  4. To adjust the belt size, simply push the ratchet buckle inwards and move it up or down the belt to a different set of teeth

Bungee Cords

  1. First, determine the size of bungee cords that you need. Measure the distance between the subwoofer and the surface where it will be secured.
  2. Secure one end of the bungee cord at one end of the subwoofer. Use a hook or a loop of the bungee cord to secure it.
  3. Place the other end of the bungee cord over the surface where the subwoofer will be secured. Make sure that the bungee cord is firmly in place.
  4. Pull the bungee cord tight and secure it. Depending on the bungee cord type, you may need to tie a knot or use a hook to secure the cord.
  5. Repeat the process for the other side of the subwoofer. Ensure that the bungee cords are securely in place and tight enough to keep the subwoofer from moving.

LATCH Mounting Points for Car Seats

  1. Place the subwoofer where you want it in the trunk.
  2. Locate the LATCH mounting points on the subwoofer.
  3. Attach the LATCH straps to the mounting points on the subwoofer.
  4. Secure the LATCH straps to the mounting points in the car.
  5. Test the subwoofer to make sure it is secure and does not move.

Adhesive Strips (Velcro Tape)

  1. Measure the area where the subwoofer is located in the trunk and cut two pieces of adhesive-backed Velcro to fit.
  2. Peel off the backing from one side of the adhesive-backed Velcro and press it firmly onto the trunk. Peel off the backing from the other side of the adhesive-backed Velcro and press it firmly onto the subwoofer.
  3. Press the two pieces of Velcro together, ensuring they are firmly attached. This will keep the subwoofer in place and prevent it from moving.

L Brackets

  • First, decide where you want the subwoofer box in the trunk.
  • Once you’ve chosen the spot, measure the length and width of the box and the area around it.
  • Mark the area where you want the brackets to be placed.
  • Drill holes in the trunk where you’ve marked, ensuring the holes are big enough for the L brackets.
  • Place the brackets in the holes and secure them with nuts and bolts.
  • Place the subwoofer box in the trunk, ensuring it lines up with the brackets.
  • Secure the box to the brackets with screws, ensuring it is firmly in place.

Neo Magnetic Quick Release Subwoofer Enclosure (Neodymium Magnets)

  1. Measure the area of the trunk that you want to keep the subwoofer box in.
  2. Purchase the appropriate size of Neo Magnetic Quick Release Subwoofer Enclosures (Neodymium Magnets).
  3. Affix them to the base of the subwoofer box. This can be done by either drilling holes and using screws and nuts to affix the magnets to the box or an adhesive to attach them to the box.
  4. After the magnets have been securely attached to the box, you will want to place a compatible steel plate on the trunk floor. This steel plate should have the same size and shape as the magnets attached to the subwoofer box.
  5. Once the steel plate is placed, the subwoofer box will then be able to be attached to the steel plate, with the magnets on the box and the steel plate creating a strong and secure bond that will keep the subwoofer box in place and prevent it from sliding around in the trunk.

Now, you can hit the road with no worries about your subwoofer box sliding around and causing a distraction while you drive.

What Are the Potential Consequences of A Subwoofer Box Slipping Or Sliding In The Trunk?

A subwoofer box slipping or sliding in the trunk can have various consequences. Here are five potential consequences of a subwoofer box slipping or sliding in the trunk:

  • Damage To the Subwoofer Box: Depending on the nature and severity of the slipping or sliding, the subwoofer box may suffer physical damage, such as cracks or dents, which can ultimately lead to decreased performance.
  • Damage To the Trunk: If the box is large enough, it may cause damage to the trunk of the car, such as scratches, dents, and even holes if the box is large enough.
  • Potential For Fire: If the subwoofer box slips or slides and makes contact with any of the electrical wires in the trunk, it could cause a spark that could potentially start a fire.
  • Damage To The Surrounding Items: If there are any items in the trunk that are not secured, they could be damaged from the subwoofer box slipping or sliding. This could include anything from luggage to CD cases.
  • Noise Pollution: Depending on the size and power of the subwoofer box, it may cause a noticeable increase in noise pollution when it slides in the trunk.

So, properly secure your subwoofer box in the trunk for optimal safety and performance!

How Do I Know If the Subwoofer Box Is Too Heavy For The Trunk?

The best way to determine if the box is too heavy for the trunk is to check the owner’s manual or the manufacturer’s website for the exact weight limit and compare it with the actual weight of the box.

If the weight exceeds the limit, you’ll need to find a lightbox or a way to reinforce the trunk to accommodate the weight.


Q: Is There Such a Thing as A Sliding-Resistant Subwoofer?

There is no such thing as a sliding-resistant subwoofer, but there are some measures that can be taken to minimize movement and keep the subwoofer firmly in place. So, if you’re looking for a subwoofer that won’t slide around, you’ll have to get creative with the solutions available!

Q: What Are the Best Methods For Dampening A Subwoofer’s Box Vibrations?

The best methods for dampening a subwoofer’s box vibrations are: using an isolation pad platform to raise the subwoofer off the floor, adding anti-vibration rubber feet to the base, installing sound-damping materials such as soundproofing spray foam, and using bass traps.

Q: Does the Size and Shape of a Subwoofer Box Affect How It Slides?

The size and shape of a subwoofer box affect how it slides. The larger and heavier the box, the more difficult it will be to slide. A box with a flat bottom and rounded edges will be much easier to move than one with a curved bottom and sharp corners.
