Powered Subwoofer for Cars Buying Guide


The beauty of powered subwoofers is that they are easy to install in almost any vehicle, and they instantly and significantly upgrade your car’s standard sound system for more bass and an overall better sound quality.

Trust me, you will definitely notice the difference that a powered subwoofer makes as compared to your typical audio system that simply doesn’t bring as much power and performance, especially since these things combine top quality materials, superior design, and advanced electronics.

But, are all powered subwoofers the same? The answer is no. Much like any other product, there are great ones, and there are mediocre ones. So, how do you find the best powered subwoofer for cars that will give you the best value for your money?

To help you out, here are the most important things that you need to look for when it comes to the best powered subwoofer for cars.

Benefits of a powered subwoofer

Benefits of a powered subwooferFirst of all, just how does a powered subwoofer benefit you? Well, here’s what it can do. Basically, a powered car subwoofer is designed for the best user experience for so many different reasons.

For one thing, it comes with a built in amplifier, so you don’t have to purchase one separately. It also comes in a compact size that usually fits under most car seats. And, it’s easy to install even if you don’t have an ounce of knowledge in electronics.

Plus, powered subwoofers generally look nice and sleek, and most importantly, they offer an amazing sound quality that you can’t ever hope to get from a factory car audio system.

Enclosure size

Now, one of the first things you need to take into account is the overall size of the subwoofer, which essentially equates to the measurements and dimensions of the enclosure. This will determine whether the subwoofer can fit under your car seat, or you’ll have to mount it somewhere else, like in the trunk, for example.

Generally, you’ll want something smaller especially if you have a small car, and you can’t sacrifice any trunk or floor space for an extra audio system. If this is the case, the most important thing to check is the thickness of the subwoofer.

You need to compare that size with the height of your car seat and be careful for power front seats that come with extra components underneath, as you’ll have to account for those as well. In such cases, there might even be instances where mounting in the trunk is your only option.

Enclosure type

In relation to the size of the enclosure is what type of enclosure it is, since this largely influences its size and where you can install it. There are generally three types of subwoofer enclosures, namely, sealed box, ported enclosure, and bandpass box.

Ported enclosure

A ported enclosure, which is also referred to as a vented subwoofer, makes use of various vents that are specifically engineered to highlight certain frequencies. These are great for low bass sounds that come plenty in hip hop, rock, and techno music.

The only thing is, ported enclosures are bigger and need more space, and as such, they are typically mounted in the trunk.

Sealed box

A sealed box or sealed enclosure is an airtight subwoofer system that features a basic design and is perfect for playing smooth, balanced, and ambient sounds that you get from classical and jazz music.

It’s also smaller and more compact than ported enclosures, so it’s highly suitable for installing under a car seat.

Bandpass box

Now, there’s also the bandpass box, which is not as common as ported and sealed subwoofer enclosures. A bandpass box is the most superior when it comes to delivering low frequency sounds and gives you the strongest and most focused bass.

Best Powered Subwoofer Size

Subwoofer sizeAside from the enclosure size, the size of the subwoofer itself is just as, if not more important. This is because it’s what determines how the speaker will sound. Generally speaking, the larger the subwoofer is, the lower frequencies you’ll get out of it.

If you’re a fan of metal and rock music, then the subwoofer size should be a particularly important consideration for you. Of course, you should also remember that the larger the subwoofer size, the more space it takes up, so you need to account for that.

Cone size

Another thing when it comes to measurements is the size of the subwoofer’s cone, which also affects the quality and depth of the bass tones you will be able to hear from the subwoofer system.

To give you an idea, an 8 inch cone delivers punchy bass sounds, while a 10 or 12 inch cone gives off deeper bass notes. Just remember, larger cones are pricier, and make for larger housings, and in turn, larger subwoofers.

Power

Do you want a loud and rumbling car sound system that turns heads as you drive past? If so, then you need to prioritize the power handling of the subwoofer system, since it’s what directly affects the maximum volume of the system.

The good thing is that most, if not all, car subwoofer systems already come with built in amplifiers, so you mostly just have to look at the wattage of the subwoofer and the amplifier to get an idea of how loud the sounds it can produce will be.

Sensitivity

One thing that’s directly related to power is sensitivity. To put things simply, a higher sensitivity rating for a subwoofer system means that you won’t need as much power in order to achieve loud and booming sounds.

On the other hand, a low sensitivity rating will require significantly more power. Meaning, it won’t be as efficient, and will consume more energy just to give you the same level of performance than a subwoofer with a high sensitivity rating can readily offer.

Resistance

Another factor that is related to power is resistance or impedance, which is measured in ohms. This will determine what kinds of wire you can use to connect the subwoofer with your car’s audio system.

The general number is around 4 ohms. 2 ohm impedance ratings mean you can use thinner wires, whereas a resistance of 8 ohms will require thicker wires for installation.

Frequency response

Finally, you should also take into account the frequency response or frequency range of the subwoofer, which particularly indicates the lowest and highest sounds that the subwoofer can produce.

I might be stating the obvious here, but a lower frequency range means you’ll be able to enjoy lower and deeper sounds from the subwoofer. But, it’s important to remember that there are lots of other things that affect the reality of what sounds you’ll get from the subwoofer.
