There is a difference in securing your subwoofer box in the car trunk to avoid its movement and truck. Installing truck subs can be an effective way to improve your music listening experience.

However, some people complain about having an unsecured subwoofer enclosure in the truck. There are several reasons, including a powerful subwoofer that hits bass harder.

You can quickly fix the securing issue by installing a mounting bracket (especially L-bracket), using velcro, or attaching bolts with a sub box. As an audio expert, I will tell you the most efficient ways to eliminate the problem below.

Let’s dive in!

How Do I Keep My Sub Box From Moving?

As discussed above, securing your sub-enclosure with brackets or anchors is the best way to keep it from moving. Depending on your setup, you may also need to use a combination of both.

When securing your subwoofer with brackets, be sure to use screws at least 1.5 times longer than the thickness of your box, allowing you to connect it firmly to the wall or floor. Consider using lag bolts or masonry anchors for added security for heavier boxes.

4 Most Effective Ways to Secure Your Subwoofer in a Truck:

After implementing many methods to secure subwoofers in a truck, I found these four methods to be effective enough to follow:

1. Use Subwoofer Box Bracket:

Subwoofer box brackets can provide you with the ease of installing a subwoofer in your truck bed. You need to attach them inside the truck bed, giving you a secure subwoofer box mount. To get started using a subwoofer box bracket:

  1. Measure and mark the spot where you would like to place the frame. Ensure you leave enough room for the subwoofer box and that it is centered in the truck bed.
  2. Drill pilot holes into the truck bed so that you can attach the bracket to the metal surface of your truck bed.
  3. Use screws or bolts to secure the bracket to the truck’s bed.
  4. Place the subwoofer box on top of the stand, ensuring it is centered and level.
  5. Secure the box to the bracket using screws or bolts. Ensure that all connections are tight and secure before playing your music.

2. Attach Your Sub Box Using Bolts:

This is also an effective way to secure the sub in a truck. However, it requires some skills to do the task successfully. You can seek professional help if you’re a total beginner. By the way, let’s get to work.

To attach your sub enclosure securely, you will need to get some long enough bolts to reach from the box’s wood into the metal of the truck bed or rear seat frame.

Once you get these bolts, you can begin attaching them by first drilling pilot holes in the wood of your enclosure. Ensure that each pilot hole is big enough to accommodate the bolts.

Once you drill the pilot holes, insert the bolts and secure them with nuts and washers. Ensure that all nuts are tight before you move on to the next step.

Now take a look at where you want to place your subwoofer in the truck bed or rear seat. Locate the nearest metal frame and mark the points where you will need to drill larger holes for the bolts.

Once you drill all holes, insert your bolts, nuts, and washers into each hole to secure your woofer box. Ensure that all of the nuts are tight to ensure that your sub enclosure is firmly in its place.

Finally, check the stability of your enclosure by pushing lightly on it. If it doesn’t budge, you successfully secured your sub enclosure using bolts in the truck bed or rear seat!

3. Install Velcro Inside the Truck Bed:

Another effective and quick way to do the job is to install velcro in the truck bed or anywhere you are willing to secure the truck subwoofer. However, this method only applies to trucks with a floor that can be attached to velcro.

The simple installation of velcro and adhesive can help keep the box secured in place while enjoying your music. Here’s how to install Velcro Velcro:

  1. First, you need to determine where you would like to place the velcro in the truck bed or other desired location. Make sure to measure twice so that you have the correct placement for the hook and loop sides of the velcro.
  2. Once you have determined where to place the adhesive, peel off one side of the backing paper from your hook, loop the pieces, and press firmly into place.
  3. Repeat the same process for the other side of the velcro and press it firmly into place as well.
  4. To help secure the subwoofer enclosure, you can use adhesive strips on both sides of the box to further ensure its placement inside your truck bed or any other desired area.
  5. Finally, test out the subwoofer by turning up your favorite music and enjoying the ride!

4. Use Powerful Double Sided Tape:

This is the cheapest way to make your subwoofer secured in your truck. Follow these simple steps to execute the process successfully:

  1. First, you’ll need to get an appropriate amount of double-sided tape (1). Ensure that the tape is rated for use in vehicles to hold up to the temperatures and vibrations.
  2. Next, you must clean the area with a damp cloth to ensure there is no dirt or debris where you want to place the subwoofer. Ignoring this step will affect your subwoofer placement.
  3. Cut your double-sided tape to the appropriate length and width for your enclosure.
  4. Now, place half the double-sided tape on the backside of your subwoofer enclosure, then press down firmly. Then place the other half onto your truck’s bed or side panel.
  5. Finally, press down firmly to ensure a secure bond between the two pieces. Your subwoofer enclosure should now be secure in your truck.

Many Positions to Secure a Truck Subwoofer:

As you know, the position of a truck subwoofer is an important consideration when completing a custom sound system installation in your vehicle.

You also have to plan the location of your subwoofer for optimal performance, safety, and convenience in the beginning. The most suitable spots for placing a truck subwoofer depend on several factors, such as the type of music you will be playing, the size and shape of your speakers, and the layout of your cargo area.

You can use these three common areas to secure a truck subwoofer: behind the rear seat paneling near the back window, under one or both front seats, or behind trim panels on either side wall in double-cab pickups.

When positioning any speaker enclosure, you must also evaluate how close they are to walls or other objects that may interfere with sound quality by causing reverberation and distortion.

To maximize bass response and sound quality, ensure enough space between any surfaces surrounding enclosures while keeping them away from potentially harmful heat sources like amplifiers or batteries.

Finally, ensure all components are securely mounted before turning on the power source so that no vibrations occur during use, causing damage!

General FAQs

How Do I Secure My Subwoofer Box?

The best method I found of securing a box is using screws to attach it to the metal on the car’s floor. However, if that’s not possible, you can use wood screws with plastic wall anchors or double-sided adhesive tape.

Make sure whatever option you choose provides sufficient stability and attaches firmly enough that your subwoofer stays in one piece, no matter what kind of bass notes get pounded out.
For added security, consider drilling additional holes around where the box meets with other materials like carpeting or upholstery, so everything stays firm.


How Do You Hold a Subwoofer in Place?

When you want to ensure the subwoofer is holding in place, securing it properly with screws and glue is vital. Secure the subwoofer by drilling four holes into the back of the box, two on each side.

Use wood glue to ensure it holds firmly, and insert each screw through the hole, tightening them until they are flush against the front of your speaker box.
To add additional support, use four conical screws that fit around your woofer’s edges and tighten those down.
