How to Find the Best 12 Inch Subwoofer

There are many types of speakers that you can install in your car to have the desired listening experience while on the road. You need something bigger and stronger, and you think a 12-inch sub fits the bill.

Now, you will have to compare different specifications to ensure that you end up with the best 12” sub.

Here are the most important factors to consider when choosing a subwoofer:

Power needs and handling capacity

The discussion about subwoofer power is multi-dimensional.

Can the existing audio system adequately power my new subwoofer? 12-inch subs consume different amounts of power to produce varying amounts of bass. If you want a sub that produces a lot of bass, it’ll consume a lot of current. Your audio system should, therefore, have power abilities close to that of the sub.

The other important consideration about power is how much power the sub can actually handle. In some reviews, you’ll see complaints of voice coils smoking because too much current was driven through them. Not fun.

It’s crucial to determine the real power-handling capabilities of the sub before putting it in the shopping cart. Unfortunately, there are subs that promise high power handling in words, but they don’t deliver.

Does it have a motor cooling mechanism?

If you’re in the market for a high-power 12-inch sub, look for the ones with a motor cooling system. Such a system makes sure that the sub doesn’t heat up or break down during long hours of application.

What about voice coils?

Although the question of single and double voice coils is crucial, it is rarely explained well. First, the choice between SVC and DVC depends on what you want from your subwoofer. 

If your main concern is how much power the sub will put out, consider the ohm load of the voice coil rather than the number of coils. Ohms measure electrical resistance, and the fewer the ohms, the more power the sub puts out, assuming a constant power supply.

You could be looking for flexibility; that is, you care about wiring options and intend to attach additional drivers to your stereo system. In this case, a DVC subwoofer is better than an SVC sub.

What does your budget look like?

No matter what your budget for the sub is, keep in mind that after purchasing the sub, you might need to spend more money on a good enclosure or on installation.

Subwoofer installation

Do you want to install the sub or have it professionally installed? 

Is the seller offering free installation?

Most subwoofers are easy to install, but you might come across a 12-inch that could make you sweat. It’s good to know beforehand about a sub’s installation. Look at the installation manual and be sure you can handle the wiring steps if you intend to do it yourself.

Other inevitable considerations include the weight and size of the sub and the required enclosure. Can the sub fit in the available space in your car?

We are sure you will find one or several of the top 12 inch subs reviewed above perfect for your listening needs and matching your car’s existing audio system.

Best 12 Inch Subwoofer FAQs

Q: How much power does a 12 inch subwoofer need and how does this power handling influence how loud the sub will be?

A: Two factors determine the amount of sound any sub produces – RMS power handling and sensitivity rating. RMS power is the amount of power a subwoofer can handle continuously. The higher the RMS, the better the sub, all other factors being constant. Note that more power doesn’t always mean louder or more precise sound output. The sensitivity rating (measured in dB) is an indication of how efficient the sub is in translating the power to the booming sound. A higher sensitivity rating implies that you get better audio even with lower RMS power handling.

Q: How much space do I need for the installation of a 12 inch subwoofer?

A: As you target to attain a certain type and level of audio, consider the space available in your car for the installation of a sub. If you have plenty of space, you have more freedom over the sub to choose from. If you lack space, you can still enjoy enhanced bass output by installing shallow-mount 12-inch subs.

Q: What are shallow-mount subwoofers?

A:A shallow-mount subwoofer works similarly to a traditional subwoofer but in a smaller package. Unlike regular subs that are deep and heavy, shallow-mount subwoofers are lightweight and shallow. Their size allows for installation in small spaces. Some manufacturers have realized the growing demand for smaller subs and now build shallow-mount units that require only about 4 inches of mounting clearance.

Q: How do I make sure that I get earth-shattering, deep bass?

A:We receive many questions on how to choose a subwoofer that delivers hard-hitting bass without affecting overall sound quality. The best 12-inch subs for deep bass don’t only have high power handling but also use high-quality woofer cones and surround material. A high power-handling capacity ensures that the sub gives hard kicks while the sturdy materials maintain excellent sound quality.

Q: Can you run two 12-inch subs in a truck box?

A:12-inch subs need space to breathe. Each sub requires at least 14 inches depth to operate without heating up. If you are placing them behind or under a car seat, make sure each has a 4-inch throw. If you are short of space in a truck, a blow through can work well so that you have enough box space.

Q. How do I choose an amplifier for my 12 inch subwoofer?

A: Use the RMS power rating to match your sub with the right amp. Go for an amplifier whose RMS power rating is between 75 and 150 percent of the RMS rating of your subwoofer, that is, the power your sub can take at chosen impedance.

Q: I already have an amplifier. How do I find a matching sub?

A: First, check the amp’s RMS power output at varying impedance levels. Divide the amp’s power output by the number of subwoofers you intend to add. The result of the division is the optimal RMS power for each sub. Also, match the impedance of the amp and the subs. Note that the wiring of subwoofers that have more than one voice coil can affect the sub’s impedance.

Q: Must I hire a professional to install my 12-inch subwoofer?

A:If you have skills and experience in car audio customization, you can handle the installation. Otherwise, the best idea is to hire a professional. You want to end up with a flawlessly installed sub for your car audio system to deliver at its best.
