Enclosures Pre-loaded with Subwoofers

Loaded Enclosures Ensure You End Up with a Perfectly Matched Sub and Box

Setting up the ideal audio system can be difficult. Perhaps you’re searching for a car subwoofer, an amplifier, or even an enclosure. You have to know how much power you need from your amplifier, what type of subwoofer enclosure to use, and what type of accessories you need for your installation. The simple solution is to order a pre-loaded subwoofer box.

In the past, these combo packages were designed for car audio beginners who wanted to test the water without much headaches. However, times have changed, and there are now many packages designed specifically for audiophiles.

What are some advantages to these types of enclosures? First of all, the manufacturer uses their insight to select the size and volume of the enclosure that will enable the subwoofer to operate at the optimal level. With this in mind, they do the technical work behind the scenes to make sure you get the best sounding system. The end result is precise calculation, calibration, and perfect tuning.

You don’t have to worry about measuring the port size or trying to figure out the internal wiring. All you have to do is place it where you want it, hook up the wires from the amplifier, and you’re good to go! They have various sizes, ranging from 8” to as big as 15” loaded subwoofer enclosures. In addition, various companies have both dual or single voice coil designs as well as single or dual subwoofer mounts. Save time and order a pre-loaded subwoofer box, you will be free of headaches and you will not be disappointed!

How to Build a Subwoofer Box

Build Your Own Enclosure

Required Tools:

  • 3/4″ Medium Density Fiberboard (MDF)
  • Power drill
  • Screws
  • Table saw (or circular saw or hand saw)
  • Jigsaw
  • Putty Knives
  • Wood glue
  • Tape measure
  • Pencil
  • Compass
  • Hammer
  • Screwdriver
  • Razor
  • Caulking gun
  • Goggles
  • Air compressor (optional)

We recommend using Medium Density Fiberboard because the density of the board will keep vibrations at a minimum. Plan ahead to ensure the box will fit in your vehicle. Once you establish how much space is available in your vehicle, calculate the box volume required for playing your subwoofer at its maximum performance level. The box volume depends on the subwoofer size. Check the table below for recommended box volumes or contact the subwoofer manufacturer for more specific recommendations.

Sub Size (inches) Box Volume (ft3)
6″ 0.36 – 0.48
8″ 0.72 – 0.96
10″ 1.2 – 1.8
12″ 2.4 – 3.6
15″ 6.0 – 10.8


Constructing the Subwoofer Box

After measuring your desired box dimensions, use your pencil to draw cutout guide lines. You should use your compass to draw the exact speaker hole and the measuring tape to determine the panel size. To make the box frame, cut the Medium Density Fiberboard with a table saw. Next cut out the speaker hole with a jigsaw. Clean up any roughness from the cuts and blow out the edges with an air compressor. Now that the main panels are cut, make sure the panels match up together by temporarily assembling the box frame.

Apply glue to the joint lines to set up the frame. It takes at least an hour for the glue to dry. After it dries you can start adding screws. Take a power drill to pre-drill your screw holes, and drill in screws to connect the panels. You should have one screw for every 6 inches along the joint line.

Scrape off the dried wood glue with the putty knives. Use glue to seal up the inside of the box to ensure an airtight enclosure. Attach the baffle board last. The baffle board is the panel that is fashioned with the speaker hole. While the box is still open, you can use a caulking gun loaded with silicone sealant to make a seal along each joint line. Once you finish caulking the joints, you can now attach the baffle board. It is imperative that you seal off the enclosure so that it is airtight. If it is not completely airtight, it will result in less power handling for your subwoofer as well as speaker distortion.

Now that your box frame is constructed, take the putty knife and apply putty along along the seams and the screw holes. Let the putty dry, and use a palm sander to first sand over the screw holes and then the flat spots. A sanding block with some sand paper will also do the trick, just use sandpaper with a 120-220 grip.

You can line your box with carpet and felt in order to match your vehicle’s interior. Spray an adhesive to attach the carpet to the box and use a razor to cut away edges and the speaker hole. Use an adhesive to add some poly-fil inside the box to maximize subwoofer performance. Now place the subwoofer in the box and mount the subwoofer box and you’re ready to rock.
