If you’re looking to add some serious bass to your car’s audio system, then you’ll want to consider building an under seat subwoofer. This type of subwoofer is designed to fit underneath your car’s front seats, and it can provide a significant boost to your system’s low-end response. 

Building an under seat subwoofer is not a difficult task, but there are a few things you’ll need to keep in mind in order to do it right. In This Blog, we’ll give you a step-by-step guide on how to build an under seat subwoofer, as well as some tips on what to look for when choosing the right components for your project.

What Type of Subwoofer Box Is Ideal for Under Seat Sub?

When choosing a subwoofer box for your under seat subwoofer, you’ll want to make sure that it’s small enough to fit underneath your car’s front seats. You’ll also want to choose a box that is designed specifically for under seat installation, as this will ensure that the box fits snugly in place and doesn’t rattle or move around. Finally, you’ll want to make sure that the box you choose is made from durable materials that can withstand the rigors of being installed under a car seat.

What You’ll Need  to Build an Under Seat Subwoofer ?

In order to build an under seat subwoofer, you’ll need the following items:

  • A subwoofer box that is small enough to fit under your car’s front seats
  • A subwoofer that is designed for under-seat installation
  • An amplifier that is powerful enough to drive the subwoofer
  • Speaker wire
  • Car audio wiring kit
  • Screws and bolts
  • Tools for cutting and drilling holes (drill, saw, etc.)

Step 1: Choose the Right Location for Your Subwoofer Box

The first step in building an under seat subwoofer is to choose the right location for the subwoofer box. You’ll want to choose a spot that is out of the way and won’t interfere with any of your car’s other components. You’ll also want to make sure that the area you choose is large enough to accommodate the size of the subwoofer box.

Step 2: Cut a Hole for the Subwoofer

Once you’ve chosen a location for the subwoofer box, the next step is to cut a hole in the floorboard for the subwoofer. You’ll want to make sure that the hole you cut is large enough for the subwoofer to fit through, but not so large that it interferes with any of the other components in your car.

Step 3: Attach the Subwoofer Box to the Floorboard

After you’ve cut a hole for the subwoofer, the next step is to attach the subwoofer box to the floorboard. You’ll want to use screws or bolts to do this, and you’ll want to make sure that the box is secure.

Step 4: Install the Subwoofer

Once the subwoofer box is attached to the floorboard, the next step is to install the subwoofer itself. You’ll want to follow the instructions that came with your particular subwoofer, but generally speaking, you’ll need to connect the subwoofer to the amplifier using speaker wire.

Step 5: Install the Amplifier

The final step in building an under seat subwoofer is to install the amplifier. You’ll want to follow the instructions that came with your particular amplifier, but generally speaking, you’ll need to connect the amplifier to the subwoofer using speaker wire. Once the amplifier is installed, you’ll need to connect it to your car’s battery using the car audio wiring kit.

Step 6: Testing A Subwoofer

After you’ve followed all of the steps above, the final step is to test your under seat subwoofer to make sure everything is working properly. The best way to do this is to take your car out for a drive and see how the subwoofer sounds. If everything sounds good, then you’re finished! If not, then you may need to adjust the positioning of the subwoofer box or the amplifier.

Things You’ll Need To Do When Building An Under Seat Subwoofer:

  1. Decide on the size of the subwoofer. The size of the subwoofer will determine how much space it will take up under your seat, so you’ll need to decide on a size that will fit comfortably in your vehicle. Generally speaking, larger subwoofers will require more space, but they will also provide more bass.
  2. Choose the right subwoofer enclosure. The type of enclosure you choose for your subwoofer will have a big impact on its performance. There are two main types of enclosures: sealed and ported. Sealed enclosures are smaller and provide tighter, more accurate bass. Ported enclosures are larger and provide more bass, but at the expense of accuracy.
  3. Choose the right subwoofer driver. The subwoofer driver is the heart of the system, and it’s important to choose one that will provide the performance you’re looking for. There are a variety of different drivers on the market, so it’s important to do your research and choose the one that’s right for your system.
  4. Choose the right amplifier. The amplifier is responsible for powering the subwoofer, and it’s important to choose an amplifier that will provide enough power for your system. Generally speaking, you’ll want to choose an amplifier that can provide at least twice the power of the subwoofer’s RMS rating.
  5. Wire everything up. Once you have all of your components, it’s time to wire everything up. This can be a daunting task, but there are a few things you’ll need to keep in mind. First, make sure that all of the connections are tight and secure. Second, pay attention to the polarity of the wires. The positive and negative terminals on the subwoofer must be connected to the correct terminals on the amplifier. Finally, make sure that all of the wirings are routed away from any moving parts or sharp edges in your vehicle.
  6. Test it out. Once everything is wired up, it’s time to give it a try. Turn on your system and see how it sounds. If everything sounds good, then you’re done! If not, go back and check all of your connections to make sure they’re tight and secure.

In The End!

Building an under seat subwoofer is a great way to add some serious bass to your car’s audio system. By following the steps outlined in this blog, you’ll be able to build your own under seat subwoofer and get the most out of your system.
