Why Do You Need High Quality Car Subwoofers Under $100?
Subwoofers are specialized speakers that only reproduce the bass frequencies of the music coming from the car’s stereo.
These bass frequencies tend to move the cone of the speaker much more violently than some of the other, higher frequencies. Because of this, these speaker cones must be of a tougher, more rugged quality than full range speakers to avoid tearing and blowing.
Luckily, there are a high number of high quality subwoofers on the market that are made of high quality materials and are still under $100. This means you can upgrade your car’s stereo system without worry about your brand new subwoofer blowing a few songs in to your playlist.

How to Pick the Best Car Subwoofers for Under $100?
Finding the best car subwoofer for under $100 will depend on a few different factors. However, knowing what to look for can help you find the best choice for your specific vehicle and situation.
In order for a car subwoofer under $100 to be a good choice, it needs to:
- Have a frequency response between 30 and 200 hz. This frequency range will be enough to reproduce all the right bass sounds without overloading the speaker itself. Almost all subwoofers under $100 will be designed to reproduce this frequency range.
- Be made of high quality materials. The best car subwoofers under $100 will not have paper cones. Instead, they will use things like mylar and rubber. Some subwoofers in the lower range will use standard speaker paper for their cones, so it is important that you make sure the one you buy uses tougher materials.
- Be able to withstand at least 100 watts. Most subwoofers will be able to handle a wattage load much higher than this, including subwoofers under $100, but over 100 watts should be enough for almost any car stereo system.
Now that we know what to look for, let’s take a look at what specific considerations to make when looking for high quality car subwoofers for under $100 .
What does a subwoofer do?
A subwoofer is a speaker that is designed to amplify the lower frequencies of the music coming from your car’s stereo.
Many stock speakers that come with automobiles are of the full range variety, which means that they are designed to amplify sounds within the entire range of human hearing ability.
Subwoofers, however, usually amplify the frequencies between 30 and 150 hz. These frequencies are responsible for the “thump” you can feel in your chest and aren’t usually particularly focused in stock speakers.
These stock speakers are usually made of paper and are not going to be strong enough to withstand the vibrations of these lower frequencies being focused and amplified. That’s why a subwoofer, which is made of stronger materials is so important for these deeper, more bass-centered sounds.
When looking for a subwoofer under $100, be sure to look at what kind of material the speaker cone is made of. Some cheaper subwoofers will use the standard, full range speaker paper in their cones.
Look for a subwoofer that uses rubber, mylar, or heavy duty speaker paper in its cone. This will ensure that you won’t run into any issues like tearing or blowing.
This video gives an in-depth explanation of why the materials that your subwoofer is made of are important and how they can affect the quality of sound:
Will You Need a Separate Amplifier?
One of the things that many people want to know when they start researching subwoofers and car stereo modifications is whether or not a separate, dedicated amplifier will be necessary.
Amplifiers are power sources for speakers. They provide the wattage that is necessary to drive the speakers and provide the movement in order for sound to come out.
Luckily, your car’s stereo will already have an amplifier built in. This amplifier should be enough to drive a small subwoofer just like the ones we have chosen for our list. In fact, some of them even come with their own power supply, so you don’t have to worry about buying an external amplifier.
However, if you are very dedicated to high quality sound, you may want to invest in an amplifier that is specially designed to work with subwoofers. This will give you a clear, focused bass sound as well as extra wattage to really kick things up a notch.
The issue with this separate amplifier is that it will end up costing you some extra money. If you are just looking for the best car subwoofer for under $100, you do not have to take this extra step.
There are some subwoofers under $100, such as our top pick below, that have their own amplifier built in. This is a great feature to look for as it will eliminate the need for a separate amp while still delivering the best possible sound.
