Sub-Box Carpet: How To Do It And Where To Get It


A subwoofer is a comprehensive loudspeaker and works to reproduce audio frequencies having a low pitch called as bass.

These frequencies range from 20 Hz up to 200 Hz for subwoofers. Subwoofers are made to enhance low-frequency ranges of loudspeakers which work on high-frequency bands. As such the term “subwoofer” means only the speaker, in layman talk, we refer to the subwoofer as the speaker enclosure along with the mounted speaker driver.

Subwoofers became quite popular with the advent of CDs and DVDs which could deliver the loud and deep bass. Subwoofers are well-accepted and recognized for sound reinforcement during concerts and nightclubs since the 2000s.

Wood has the capability to withstand air pressure and resist deformation making them perfect for the construction of subwoofers. They are available in diverse designs based upon efficiency, cost, low-frequency range, and cabinet cost.

Some of its designs include infinite baffle, bass reflex, bandpass, horn-loaded acoustic suspension, etc. Active subwoofers incorporate an inbuilt amplifier. Passive subwoofers have driver enclosure along with the speaker and utilize a peripheral amplifier.

Passive subwoofers have a subwoofer driver and enclosure and they are powered by an external amplifier.

Subwoofer boxes in vehicles are preferred by music lovers to get the desired acoustic effects. There a number of different types of architecture and construction. Today, we shall be discussing on the carpeting of subwoofer boxes

Boxes with vents give more bass, however, nothing can beat the quality of sound in a sealed box.

What is a Sub Box Carpet?

Sub box carpets are carpets that are used to your sub-woofer box to give them a professional appearance. Prefabricated subwoofer boxes available from the market, come wrapped in the carpet.

It is quite simple to make your own subwoofer box. This custom box will even match perfectly to your custom speaker.

You need wood and a few handy tools to make the subwoofer box. After the hole for the speaker is cut and the box is assembled, it is time to cover it with a carpet.

Uncovered boxes will look quite unprofessional and underdone. Just buy a carpet from amazon or any other website or shop. These carpets come in a variety of colours to suit your car within the cars’ hood.

Please consult the company or the shopkeeper and select thicker cloth for this purpose.

Please note that there are no acoustic benefits due to carpeting the sub box. Carpeting is a great option since it matches with the cars’ interior.

Painting is also okay, but it requires a good amount of time and effort. Generally, people prefer carpeting their sub boxes.

Why Do You Need A Sub Box Carpet?

They need to match with the vehicles’ internal carpeting.

How To Carpet Your Sub Box?

These carpets are available in a number of colours and you can select them from Amazon. You might have to select a carpet with adequate thickness and colour to match your vehicles’ internal carpeting. It is quite simple to succeed in carpeting your sub box.

Materials required:

To go ahead with the carpeting, you might need the following tools and accessories:

a) Carpet material

b) Cutting tools / Utility knife / Staple Gun

c) Adhesive / 777 Glue / Contact Cement

d) Staple gun

a) Carpet Selection:

A number of different types of carpets are available. Please do not select ones with rubber backings. They are quite difficult to work with. They are unable to bend sharply and even more tedious to cut.

The household carpet also fails as it is flexible than solid rubber, simpler to cut but still difficult. The best ones are the Auto Liner carpet ones which are stretchable, flexible and thin.

Although they appear to have weak quality, they are the best ones suited for this job. You can get sharp corners and straight sides and also cut them promptly and neatly. These are available on major internet sites and also auto dealers.

b) Cutting Tools:

A number of different tools will make your job easier. First and foremost is a sharp utility knife. Razor knives work well but their blades dull rapidly.

We recommend the putty knife of 1” width and sharpened with sandpaper on a belt sander. This sharpens the knife along the job and works for longer time uninterrupted. You may even knives having snap-off blades.

c) Selecting an Adhesive:

Spray adhesives are most widely used for subwoofer carpets. They do fail for heavier carpets and they do not hold for very long life for lighter ones.

However, they can do the job quite quickly and efficiently. Professionals prefer contact cement. It will hold practically along the life of the subwoofer and does not get affected by heat.

Contact cement (use the Dap contact cement from Amazon) has to be applied to both surfaces. Let it dry for 5 to 15 minutes and join the parts. The parts will be in Contact for life hence the name of the cement as Contact Cement. Use a roller or brush to apply the cement.

Contact Cement works with solvents that must evaporate before the adhesive dries up. As the solvent gets evaporated, the surface begins to cool.

In humid zones, condensation will take place on surfaces. Moisture weakens the bond. It is better to carry out using contact cement on days when it is not raining.

Else use heat guns to maintain the surface to be free from moisture. While using heat guns, you must provide sufficient ventilation. Although, being non-flammable, contact cement does require a good amount of ventilation.

You may choose the adhesive as per your comfort and convenience.


Please select carpet of adequate thickness as per recommendations from the site. Apply the adhesive at one side of the sub box (do not select the side with the hole). Then stick the carpet to that side.

Repeat this steps for the others sides of the wooden box.

When the final side comes, apply the glue, and stick the carpet. Use the utility knife provided to cut the carpet appropriately so that you get a great professional finish.

Make sure adequate glue is applied and left to dry so that the carpet sticks tightly to the box and does not become loose. The box is going to house the speakers with huge sounds and vibrations so the sticking process has to be above average.

Use handgun selectively to attach the carpet to the wooden box. You may even use the Contact cement in place of glue. This does make a stronger bind but the cement is tougher to work it. Use it if you are sure of managing it, please go ahead and try.
