The world of car sound system competitions has grown in popularity over the recent years. Organizations like IASCA (International Auto Sound Challenge Association) and MECA (Mobile Electronics Competition Association, Inc) hosting competitions anywhere and everywhere that audio enthusiasts want to compete in.
These competitions can vary in how they work and what their rules are, but two of the most common types involve testing the sound quality (SQ) of speakers over time with sustained music and testing the max sound pressure level (SPL) in a quick burst of bass.
If you love the sound of thumping bass as much as we do, and you think you want to test yourself against other audio enthusiasts in one of these competitions, then you are going to need the best competition subwoofers.
And even if you don’t possess the competitive spirit, if you want premium bass in your aftermarket sound system then you have to consider a premium competition subwoofer.
The demands of a car audio competition require special considerations. We’ve done the heavy lifting for you and compiled a list of the top competition subwoofers available on the market today.

What to Consider When Choosing a Competition Subwoofer
We’ve looked at the best competition subwoofers on the market and highlighted what each one is best suited to do for you. With this information, you might feel like you’re ready to get out there and compete.
But just because a subwoofer might offer more power, a more comprehensive frequency response range, or come with all the additional components of a competitive sound system doesn’t necessarily mean it’s the best choice for you.
Allow us to break down some of the critical factors that affect how a subwoofer performs and why it matters when you want to use them for audio competition.
In general, the rule of thumb for aftermarket subwoofers is the bigger a subwoofer is, the bigger the bass will be. The size will also factor into how low you go for that desirable, deep bass.
A larger sub typically offers less responsiveness than its smaller siblings. If you are competing in a sound quality test, you might favor the SQ performance of a smaller subwoofer.
Another size aspect to consider is the space you have available. If you want to get the most out of your competition build, you need to maximize your use of space. Measure your trunk or another area of the car you are using to house your sound system and get the most significant sub you can.
Power in a subwoofer consists of two measurements: root mean square (RMS) and peak power. Peak power is the maximum amount of power a sub will take before blowing out, but for competition subwoofers – and audio equipment in general – RMS power is a more significant measure because this is the sustained output your sub can handle.
1500 – 2000 watts is good for a competition subwoofer, but if space and budget are of concern then there are solid offerings in the 1000 watts range like the Skar Audio car subwoofers.
Both RMS and peak power can factor into how well a subwoofer will do in competition, but it is not the only thing to consider when looking at the power rating.
The efficiency of the sub’s other components is going to play a huge role in how well all that power translates to the sound quality and SPL (sound pressure levels).
The frequency response refers to the range of sound that that subwoofer can reproduce. To create deep bass in competitions, you want to find a sub with an excellent low-end frequency.
Humans can hear as low as approximately 20Hz, and that is when you get that chest-shaking, vibrating bass that you feel more than hear.
Don’t forget to analyze your enclosure when you’re considering frequency response. An enclosure will modulate the music and will change between the frequency that the sub is putting out and what you hear.
Another term for SPL is sensitivity, and it refers to the subwoofer’s ability to utilize power to create a particular volume.
The higher a subwoofer’s SPL, the less power it requires to reach a given volume. Another way of saying this is that the more sensitive a subwoofer is, the louder it can be with less power.
Sensitivity is measured in decibels or dB. Look for a sub with an SPL rating in the mid-80 dB range for good performance, with anything 90 dB or higher being very competitive.
A more sensitive subwoofer will also require a less powerful amp which can be a consideration if you are concerned with the costs of the rest of the audio equipments for your build.
The impedance, or Ohm’s law, is the measure of the sub’s electrical resistance. It’s vital to match your sub’s impedance and the impedance of your amp for the best performance.
A low impedance means that a subwoofer is more conductive and will more accurately produce sound than a sub with a higher resistance rating.
Other factors influence the impact of impedance, including the number of voice coils, the voice coil materials, wire gauge, and the way you wire your sound system. Try to find a sub with low impedance and build your system to maximize efficiency.
Subwoofers need to be mounted in boxes called enclosures with the right volume of air inside to produce the best sound and there are a number of ways you can do this.
Sealed enclosures require less space and produce a tighter sound – but they require more power, whilst vented (or ported) enclosures demand more space and hit lower frequencies.
Most subs can be mounted in either sealed or vented enclosures – but make sure you’ve got the space to do it right if you want to be onto a winner
Car audio competitions are a ton of fun, and the subwoofer is a key component in achieving success in the hobby. Remember to check the guidelines of your competitive organization for any rules about the kind of audio equipment you are allowed to use.
Remember that different competitions test different aspects of sound. What you want from a subwoofer will depend on if you are at a competition testing SPL, SQ, or another metric. You may want to try to find a subwoofer with decent performance across the board, or maybe you want one that focuses on one aspect and really shines.
Read through our guide on how to choose the best competition subwoofer for you. Use it as a roadmap that can narrow down your search for a sub that hits all the performance metrics you want for your system.
The competition subwoofers on this list are a great place to start looking. Each one is geared towards providing an impressive competition performance.
And no matter which one you choose, always remember to turn on the music, crank up the volume, and that bass bumping.
