Buyers’ Guide when Choosing Subwoofers

Typical Costs of Car Subwoofers:

The typical cost of the best subwoofer depends on a lot of features, as you might imagine. Whilst every option we’re bringing you in this list is easily affordable, you have to consider factors such as sound quality and the voice coil. For example, a dual voice coil with dual 4 ohm technology will inevitably be pricier than that of a single voice coil with 2 ohm technology.

What’s more, the type of subwoofer can affect the cost due to materials used; for example, whether your device has a polypropylene cone and a sealed enclosure, or whether it’s entirely different.

Nonetheless, all of our picks range between as little as under $20, and as high as $300. This noticeable price range will allow you to filter out the different elements of your subwoofer speakers to find one that boasts peak performance without giving you a Rockford Fosgate price tag.

Considerations for Buying Car Subwoofers:

As we just stated above, the type of subwoofer models you buy will affect the price almost inevitably. Therefore, it’s really important that you consider the sound quality and power mechanisms of your sub before purchasing. Here are our top considerations for purchasing subwoofers; cars are delicate systems, so you really need to find the best subwoofer for the job.


There are different types of subwoofers that correspond to the different needs you may have. If you…

…want to build a personalised system then you’ll want to look at component subs. These are just the speaker themselves, usually ranging from 8″ to 15″, which need to be mounted onto a subwoofer box. They can operate on low or high power and have different impedance and voice coil set-ups, so you can easily tailor components to your car’s system.

…want an easy off-the-shelf model then you’ll want enclosed subs. These are already mounted into a box to accommodate the speaker. You’ll therefore have less to do when designing your system. A downside is that you’ll be limited on choice, and will still need to shop for an external amp to power your sub.

…want a space-saving bass system with everything included then you’ll want a powered sub. These subs contain a built-in amplifier right off the bat, meaning the work you need to put in is minimal. These subs are compact and won’t take up space – and whilst they’re great bass producers, their smaller drivers might not provide the sound power rating you’re after if you’re a big music critic.

…want a sub that perfectly blends to your car’s interior then you’ll want a vehicle-specific sub. These subs are designed with easy wiring options to provide the best bass pulsations to your car without complicated wiring configurations. The high level inputs are easy to control as your sub is highly specific to your vehicle.


If you want a system with booming bass reproduction, then you’ll need to consider power. The key thing here is to consider RMS power ratings, NOT peak power ratings (both in watts amount). RMS measures the continuous power output and is more realistic than peak power, which will give you an indication of the maximum power your subwoofer and power amplifier can get up to. As a rating process, RMS is highly effective – so make sure your sub can at least handle your amp’s output power for the best bass sounds.

One of the best things about subwoofers, whether passive subwoofers or otherwise, is that you’re afforded a lot of power handling within the system as a whole. This is especially important to consider when you realise that powerful, accurate bass production requires a lot of watt power. Therefore, a more effective system means less power used overall. This can also emit less heat and avoid a high temperature which may lead to overheating if your sub’s cooling system is not the best.


Sensitivity is the other spec that goes along with power to indicate the high output you’ll be after. A sub with a higher sensitivity rating requires less power overall to produce the same sort of sound as a model with lower sensitivity. This, again, is more efficient when considering the watts RMS rating, because you’re more likely to get great music power handling capabilities and a power source that isn’t prone to overheating.

The best budget subwoofers on the market will therefore offer fab output capability, a premium sound experience, but with quality, safe construction that doesn’t put a dent in your bank account.

Frequency Range

The key question here? How low can you go?!

Frequency range gives an idea of how low a subwoofer design can reach in terms of bass. Music articles are packed with music reviews and user reviews that analyse the product rating process undertaken by car audio enthusiasts when they analyse their subwoofers. The key thing that stands out in every subwoofer level is the base level control.

This makes all the difference and is one of the more important specifications to use, out of the many ones we’ll tell you to take into consideration, in order to find products that have efficiency in mind. Remember though, that the overall performance and clarity is part of other variables such as the spaces the sub is placed in and the box type installation – this number of factors provide an important crossover.


What is impedance, you may ask? Well, thanks to us, you’ll know everything there is to know about the impedance of your amplifiers.

Impedance is the level of resistance offered by an electric circuit to the flow of an AC (alternating current). The units that measure impedance are ohms.

A subwoofer rated at 2-ohm impedance will give you more output than a 4-ohm model – provided the wattage in amps is similar – because the resistance is lower. The most popular series of subwoofers that pack a punch, with enclosures or not, are rated at 4 ohms. However, 2-ohm models and dual voice coil has taken shape on the market.

Therefore, you need to look for amplifiers that will match your sub along the line of power and impedance.


Another commonplace factor that many people tend to overlook is size. The size and depth of the boxes or cones in the unit can affect the performance of your subwoofer quite a bit, and in an important way.

Size depends on a variety of other features such as power, sensitivity, and enclosure type. If you want a system that plays the loudest and lowest, you need a bigger sub. But don’t discount smaller subs straight away – the more space-efficient models can give you a generous sound output. Comb through links to every Amazon review or advertising outlet to find the right model for you.


Before you bring your brand new loudspeakers home, you’ll want to make sure the company you’ve opted for boasts reliability, strength, and has plenty of recommendations. If you have any doubts about the sorts of brands you want to go for, and which have the advantage over others, read on to our handy advice in this FAQs section.

This is taken straight from posts in review comments and every reply post available. Any problem, reason, or conundrum that could affect your choices is addressed here – just name it. And, if in doubt – email the company.

What Is a Subwoofer and How Does it Work?

Your very first question, if you don’t already know the answer, is going to be: what is a subwoofer, and just how does it work?

In layman’s terms, a subwoofer is a low frequency producing speaker which contains one or more ‘woofers’. Once housed, this is sometimes referred to as a loudspeaker. Subwoofers are designed to handle bass and sub-bass frequencies to very high abilities, giving you the sorts of booms your Grandma complains about.

Standard speaker sets can handle a range of inputs naturally, but with the addition of a subwoofer you get more bass thump in the trunk – so it’s clearly a good investment for any audiophile.

Here’s how they work:

  • Subwoofers need lots of air and require a lot of power in order to generate high volume bass over a small bandwidth. If you’re after studio-level bass, you’ll need a large bass driver.
  • Subwoofers are driven through electromagnetics; they have a stiff cone driven by a single voice coil, centered in a magnetic field.
  • Some have numerous voice coils. The voice coil is attached to the back of the speaker cone and moves when current flows through it, pushing the cone which moves in and out to create motion waves.

What Is the Hardest Hitting Subwoofer Out There?

Lots of reviews will tell you that popular models such as the Rockford Fosgate P3D2, or the Pioneer TS SW2502S4, is the best and most powerful hard-hitting subwoofer you’ll get; complete with a high-power watt amplifier, a high watts peak power, dual voice coils, a decent motor structure, and all the trimmings…

However, our hard work trawling through every comment name of reader interactions has shown that you can find a high quality, hard hitting subwoofer for a fraction of the Rockford Fosgate cost.

Are 10 or 12 Subs Better?

Whether 10″ or 12″ subwoofers are better really depends on what you want out of your car subwoofer and what you want the high quality bass sound to feel like in your car. One consideration is the clarity and cleanness of the sound, whereas another consideration is the depth and volume of the sound.

If you’re one for a low, booming bass, you’ll be looking for a very particular subwoofer. Here’s how 10″ and 12″ subwoofers differ, so you can make the ultimate choice about which is better for you:

Advantages of 10 inch subwoofers:

  • Sounds cleaner
  • Packs a harder punch
  • Combined cone surface area yields more sound pressure

Advantages of 12 inch subwoofers:

  • Sounds deeper
  • Larger
  • Drives frequency response down

It should be remembered that this question is really hard to answer definitively because so many factors are involved here, including enclosure type i.e. sealed enclosure, type, and size. The key things to think about when finding a sub that plays the loudest and deepest are:

  • Sensitivity
  • Enclosure type
  • Available power

It’s sometimes beneficial to look for a model with a built-in amplifier with ‘bass boost’ qualities.

Why Does the Number of Voice Coils Matter?

The number of voice coils you opt for matters because you get an increased range of flexibility in your wiring system.

Most subwoofers have a single voice coil (SVC), though a lot nowadays come with DVC (dual voice coil) – these use two separate voice coils, each with their own connections, mounted to one cylinder and connected to a common cone.

DVC subwoofers offer more wiring options and therefore a better quality of sound overall. They are the apex of surround sound and give you a great degree of cone control, maximising on cone design and speaker wire systems to enhance your car amps to the max. If you’re looking for a DVC’s pros, great. Here’s what every car audio enthusiast needs to know about why DVCs are better than SVCs.

  • Parallel: A dual 4 ohm coil with coils wired in parallel gives your amplifier a 2 ohm load. An amplifier produces a larger wattage power at lower impedance, so this parallel connection means that you’ll get the best output from your amp. If you have a stereo amplifier and 2 DVS subs, wire both for 2 ohm impedance.
  • Series: Series wiring allows you to hook up multiple woofers to one amplifier without sacrificing the impedance. If you wire both coils in series for an 8 ohm impedance and then wire 2 8-ohm subs together in parallel, you’ll get a total of 4-ohm impedance.
  • Independence: You can also wire each ohm voice coils to a separate channel if preferred. This is an ideal option if you have a 4-channel amp and want to wire 2 DVC subs, giving one coil per channel. This makes a deep bass sound, which you will find on the best high-end, and not low end, woofers. This technique makes a bunch of differences, and gives you more flex space in your setup so you can capitalise on functionality of your purchase.

Keep this in mind before making your purchases so you can hit the ground running and get max bass peaks per surface area.

Are Car Subwoofers Worth It?

Car subwoofers are most definitely worth it to ensure you get all of the features, including bass exposure and RMS power, that you’re looking for. A well-matched and efficient sub can dramatically change and enhance your overall sound output.

A subwoofer, driver for bass, and power amp – as well as a decent enclosure box (enclosure is important) – can make all the difference when getting those sound waves that will provide the best bass depth to the human ear. Any chosen product RMS power rating needs to be decent for apex surround sound, whilst the cone structure, compression terminals, and voice coils’ impedance will give your car seat the absolute best audio signal and bass solution.

Finding the right sub with a decent companion enclosure surface area, mono amplifier and input control can make a larger difference than the sort of car subwoofer brands you opt for – as many brands will offer similar features.

What Frequency Range Should I Look For?

Frequency range is another pivotal feature if you’re looking for quality sound and volumes and don’t want to make a return via warranty.

Most subwoofer units operate with a 20-200 Hz (Hertz) frequency, whilst professional live sound production uses under 100 Hz.

Different companies will offer slight variations in the frequency at hand that you should operate with, and you should always keep into account the different specs of your unit and compatible systems.

Here are some top tips you’ll want to treat as fact in your head when you follow the course of doing research for a decent sub. There’s a chance you could be buying absolute garbage and sometimes there are no ways of knowing… so follow your common sense and use this guide:

Given that human hearing goes from around 20 Hz to 20,000 Hz, frequency range can be divided into categories like so:

<20hz Infrasound

20 – 80hz audible Bass

80 – 300hz Kick bass

300 – 1000hz Lower Midrange

1000 – 4000hz Upper Midrange

4000hz – 20khz Treble

You can see that the general frequencies offered by subwoofers are anywhere between audible and kick bass, meaning these woofers will have brilliantly high resonance of lower bass volumes.

You’ll need to note that you should NEVER purchase a sub from a manufacturer who doesn’t provide:

  • A frequency measurement
  • The Thiele-small-parameters, abbreviated as TSP

Follow these tips when looking for quality bass setups to ensure you’re not being scammed for a quick commission opportunity. Some types of model may have the looks up front, but you need to know your rights as customers, and your needs, before you even think about buying.

Most companies will recommend that you limit your woofer’s frequency to a range of 20-100 Hz, using a crossover.
