Subwoofers help to reproduce low bass sounds and create a more dynamic sound. Trucks typically have different mounting needs because the interior cabin is so small. Shallow mount subwoofers designed explicitly for smaller interior cabins are perfect for truck owners.
Installing a subwoofer will provide a strong bass and sub-bass sound that will give you the optimal audio experience. A standard speaker won't come close to the power, volume, and quality of a high-quality subwoofer.

How Do I Choose A Subwoofer for My Truck?
Power Output/Volume/Sound Quality
RMS measures how your speaker performs continuously, whereas peak power measures the maximum power output. RMS is a better indicator of how well speakers work because it measures the most consistent volume rating.
The frequency response will tell you how well your subwoofer can respond to different frequencies. Subwoofers react to low frequencies and should have ratings in the 20 to 200Hz range.
The impedance rating demonstrates the sound quality of your subwoofer. The lower the rating, the better the sound quality is, and the better your subwoofer will perform. A subwoofer at 6 ohms to 8 ohms is acceptable, but a subwoofer at 2 ohms or 4 ohms is the best sound quality. Subwoofer above 8 ohms will showcase poor audio quality.
Sensitivity ratings measure how clear, loud, and accurate the sound playback will be with your subwoofer. Look for a high sensitivity rating for best results.
Subwoofers come with either a single voice coil or a dual voice coil. Single voice coils offer one connection. Dual voice coils offer multiple wiring options and are more convenient for truck owners though not necessary.
Cone Size & Subwoofer Shape/Dimensions (Design & Style)
We recommend choosing a shallow mount design for most trucks because this design can fit in tiny spaces. Trucks often have fewer options for mounting subwoofers, and you can make the most of your space with a shallow mount design. Many different cone sizes and shapes can come in shallow mount designs.
Extra features include suspension options: soft suspension, standard suspension, and extra stiff suspension. We recommend a subwoofer with a soft suspension in most cases, because these typically have the best sound in vehicles although the size of box and construction matters too.
Most subwoofers come in sealed boxes or ported boxes. Sealed boxes are self-sealed and offer a clean sound, but will need additional amplifier power to generate a loud sound. Ported boxes will automatically be louder and have that “boom” sound that some truck owners love, but these boxes are more difficult to tune and customize. A bandpass enclosure is also a possibility, but these are extremely large and difficult to fit in a truck.
Most subwoofers come with limited warranties that range from one to three years. Typically, the longer the warranty, the more durable the product.

This convenient subwoofer comes in a compact, hard, durable plastic mold, that can be easily placed underneath one of your seats. Simply slide the subwoofer under your truck seat and then set up the wired connections.
These speakers are only 8” but deliver great bass sound with a low impedance of 4 ohms. The low profile woofer won’t be able to create as strong of a bass sound as other units, but those units won't fit under your seat. A class D amplifier is included, and a low-pass crossover variable can reach frequencies from 50-120 Hz.
Aesthetically, this unit is primarily composed of low build parts, including lots of plastic pieces. However, you won’t see these speakers as they fit under your truck seat. The hard plastic components also create a more durable subwoofer that can stand up to being accidentally "kicked" by passengers from time to time.

best subwoofer for regular cab truck
12 inch speaker
150 watts RMS, 300 watts Peak Power rating

The ASC Package Dual subwoofer speakers are one of our most affordable 12” speaker options. These subwoofers are also great for a standard cab truck because they were designed specifically for that type of vehicle interior.
Little mounting depth at 5-5/16” inches makes it easy to install these speakers without losing vital interior space. With a low impedance of 4 ohms and a frequency response of 27-500 Hz, these subwoofer speakers deliver exceptional audio quality.
The gray carpet enclosure covering is not aesthetically pleasing and the build materials could be of a higher quality. That said, the materials are acceptable for the price point. The sealed enclosure is a selling point because you won't need to enclose these speakers yourself.
The sealed truck sub box is already built and constructed with strong MDF. A high-temp coil wire and vented pole piece, as well as a coil-cooling perimeter venting add-on, keep this speaker from blowing up. However, make sure you use an appropriate amplifier to avoid blown speakers.
If you need an inexpensive speaker option, this is a great choice. American Sound offers a one-year limited warranty for their speakers. This is the standard speaker warranty so you can rest easy knowing your budget but still comes with the same protections more expensive speakers do.

Truck Speakers vs. Subwoofers
Your standard truck speakers provide a great mid and high-frequency audio sound system, but cannot hit the low bass and sub-bass frequencies that a subwoofer can. If you want superior sound performance at the lowest bass levels, then you want a subwoofer.
The woofer and tweeter in your current truck speakers can continue to hit the mid ranges and high ranges while your new subwoofer takes over the bass and sub-bass ranges. This creates the ultimate sound experience. Don’t settle for less with standard speakers. Get your subwoofer installed and start experiencing strong bass with your music.
Truck Subwoofer Installation
Every subwoofer has its own specific installation instructions. However, the overall installation process tends to be similar.
To start, you need to decide where to place the subwoofer in your truck. The best place to install a subwoofer in your truck is under the rear seats. To do this, you will need to remove the underlying structure and place the subwoofer with its enclosure there. This will require tools.
Once you have installed the subwoofer, you will need to connect the wire to attach the amplifier. Most amplifiers are placed under the hood. When installing the connecting wires, be careful to securely attach them to the vehicle, and conceal them.
The final step involves connecting the amplifier cable to the stereo and RCA ports. When you have finished the installation, check to make sure that everything works by turning your speakers "on" and playing some music. Then, put the rear seat back and enjoy your new audio system in your truck.

Common Subwoofer Issues & Fixes
One common subwoofer problem that truck owners experience is a “clipping” noise. This noise typically occurs when the amplifier does not have enough power to support the subwoofer. This can also happen when wires are not fitting correctly or have been burnt.
To fix this problem, check your amplifier and subwoofer specifications. Does your amplifier have enough power to run your subwoofer? If not, upgrade your amplifier. Next, check your wiring connections. Are any of the connections burnt or loose? If so, purchase and install new writing cables.
Another common subwoofer problem is when the power won’t turn on. In this instance, you first want to check the wiring on your subwoofer and amplifier. However, if your speakers still won’t turn on, it’s time to consider your vehicle’s battery.
Too many truck owners are unaware that if your battery is old and inefficient, it may have a difficult time powering your subwoofer. The quick fix here is to replace your truck’s battery. You can test your battery for free at an auto shop.
Essentials for Truck Subwoofers
People Also Ask (FAQs)
Do I really need an enclosure for my truck subwoofer?
Truck subwoofers that have more of a “tight” and “clean” bass sound are enclosed in a sealed box. However, truck subwoofers that have a more “boom” and “loud” sound tend to be in a ported box. You do need an enclosure for your truck subwoofer, but you can choose from a sealed or ported enclosure option.
What is the best subwoofer size for my truck?
The best subwoofer size depends on the amount of space available in your truck cabin. Most truck owners choose 10” or 12” subwoofers, but some can fit 15” subwoofers in their vehicles. The 12” model is recommended for most truck owners because it offers slightly elevated sound quality and volume compared to a 10” model.
How many subwoofers do I need for my truck?
We recommend purchasing two subwoofers for your truck to create the ultimate sound experience. You will get greater clarity, stronger sound, reduce resonance, and create more of a surround sound stereo system. If you want the ultimate audio experience in your truck, you want two subwoofers.
What brands are the most reliable and provide the best warranty terms/customer service for truck subwoofers?
We recommend choosing a truck subwoofer from the following brands if you want a reliable product with great customer service and a strong warranty: JL Audio, American Sound, ASC, MTX Audio, BassPro, and Bose.
Truck subwoofer speakers will take your audio experience and enhance it so that you can enjoy the bass and sub-bass frequencies in your music. Standard truck speakers might capture the mid to high frequencies, but they simply cannot deliver those low frequencies the way a subwoofer can.

These speakers have everything that a truck owner could want: low impedance rating, shallow mount depth, reliable peak power, RMS power handling, and high-quality build materials.
