Buyer’s Guide 

Now that we have spoken about which speakers to buy le us help you understand what you should look for when deciding which car audio system to purchase. All of the considerations below are intended to hep you choose a subwoofer with the most clear and loud sound. The car audio industry is not the most well known out there and we hope to demystify that in the process as well.

Not too sure what you need from your new subwoofer? Let our buyer’s guide help you there and show you all the factors you should consider before making your purchase today! 

Power Rating 

To get the bass that you want, you will need some serious firepower in your subwoofer! The power ratings of your subwoofer will be clearly labeled in the product description, but it’s worth noting that there are two power ratings: RMS power and peak power handling, better known as peak power. Both refer to different things, so let’s take a look below at them. 

RMS power – refers to the power your subwoofer can handle continuously. Ideally, the amp should be able to pump 75% to 150% of this power rating. 

Peak power – refers to the amount of wattage the unit can cope with in short bursts. Continually pushing your subwoofer to operate at peak power can damage it and leave you shopping for a new woofer soon than you expected! 

Be sure to check both ratings when shopping for your subwoofer to ensure it is powerful enough for you! 


Sensitivity is another factor to consider and is often viewed as the most crucial spec to consider. Why? Well, because the sensitivity refers to the subwoofer’s ability to convert its power into an output volume. In short sensitivity and sound output are closely related.

This sensitivity is measured in decibels (dB), and you should see it mentioned in the product description. (db) is essentially the measure of how efficient the subwoofer is at producing sound.

The loudest 25-inch subwoofer with a high sensitivity rating should be able to produce an earth-shattering amount of bass, even if it has limited input power! Where possible, opt for the highest sensitivity level you can find. 

Frequency Response and Frequency Range 

All sounds, both the ones we hear and don’t hear, have a place on the frequency scale. The frequency range on your subwoofer will indicate its ability to reproduce various sounds, with the wider the range being, the better. 

To put it simply, think of frequency response as the ability of a subwoofer to reproduce a wide verity of sounds.

As your subwoofer’s job is to produce low bass, focus your attention on the lower end of the spectrum. The best 15-inch subwoofers should feature a frequency response that goes as deep as 20-30Hz. Be sure to check the frequency response before making your purchase. 

Enclosure Type 

The enclosure type that your subwoofer has isn’t just for appearances but plays a role in the quality of the output you get, impacting the subwoofer’s performance. All good quality 15-inch subwoofers can be divided into two groups that you can select from: 

Sealed enclosure – doesn’t have any openings and will give you a controlled, deep, and accurate sound. 

Ported enclosure – features openings (ports) that allow for improved airflow and louder output. The loudness comes at a price, though, and that is accuracy. Your sounds might not sound accurate, especially at the far ends of the sound spectrum (very deep or low bass). 

When choosing between the two types, consider whether the volume is more important than your accuracy. Considering these factors will often help you make your decision with ease. 


Another factor to consider is the number of voice coils that your subwoofer has. It’s worth noting that while it doesn’t impact the subwoofer’s output quality, it has a significant impact on the compatibility of the subwoofer. 

Ideally, you want a 15-inch subwoofer with dual voice coils, as these can be used in series and parallel setups. Dual coil subwoofers tend to be far more versatile than single-coil subwoofers.

These single-coils can only be used with the most basic, affordable sound systems. While they are fine for first-time subwoofer owners or those on a budget, where possible, we recommend opting for a dual coil subwoofer. 

They are more expensive, yes, but they are worth investing in and offer far more versatility that allows you to create the sound system of your dreams! 


For those unsure what we mean here, don’t panic! Impedance is another technical term that doesn’t mean much in terms of output quality, but when it comes to deep, strong bass, it’s a term you will want to be familiar with! 

Impedance refers to the level of resistance the subwoofer brings into the electrical circuit. This feature is measured in ohms (did anyone else get a science lesson flashback then?) 

So why should we be bothered about impedance and Ohms? Well, each amplifier is designed to perform with a certain impedance in mind. Most of these units will support a 4-Ohm impedance; you can get 2-Ohm or 8-Ohm units, too, although they are more uncommon. 

To ensure you have the best level of versatility, opt for a 4-Ohm subwoofer or a unit that allows you to switch between different impedance settings. It’s worth noting that subwoofers that can switch between different settings tend to be more expensive. 

How much?

When purchasing your subwoofer, one question that haunts you is bound to be the cost! These speakers can range from affordable to downright pricey, and it’s hard to know how much to spend. We recommend setting a clear budget beforehand and sticking to it as best as possible. 

Consider the features you want from your subwoofer, and use them to set your budget if you are unsure how much to spend. Remember, you don’t need to spend a fortune to get a good quality 15-inch subwoofer. There are plenty on the market to suit all budgets!

Frequently Asked Questions

Got some burning last-minute questions? Get them answered here! 

Where should I put a subwoofer in my car? 

Whilst this product only mentions 5 products, there is a lot more to learn about subwoofers and how they operate. If you want to Markedly improve the sound quality in your vehicle, adding a subwoofer is by far your best bet.

You can place your subwoofer wherever you want, providing that you can connect it to the rest of your sound system! Popular options tend to be under the front passenger seat, between the rear seats, in your trunk, or on the back shelf. You might want to play around with the placement of your subwoofer to get the right setup for you. 

Ideally, you want the bass to fill your car, so your setup might need to be tweaked to suit the style of your car and the free space you have. 

Should I get an enclosed subwoofer?

Its call comes down to personal choice! An enclosed subwoofer is easier to build a sound system with and is often easier to set up and install! However, they can be quite bulky and tend to take a lot of freedom out of your hands. 

You should strongly consider your options and maybe check out some enclosed subwoofers to see if they are right for you! Be sure to measure your space beforehand to check if they will fit and how they will suit you and your subwoofer needs. 

Is a dual voice coil subwoofer better than a single coil?

We think so, yes! Dual voice coils allow for more setup options and versatility, making them the better option. However, they are more pricey and can sometimes be out of budget for people. It’s best to consider your situation and pick the subwoofer that best suits you. 

For example, first-time subwoofer owners or budget sound systems are usually fine with a single voice coil subwoofer and will upgrade when they are financially able to. Remember to make the choice that best suits you and your needs.
