8 Inch Subwoofers Buyer’s Guide
All the figures above are the best 8 inch subwoofers which are different from each other, and so are the materials used to create them, so how do you know which is best for you? Since there are a ton of car models available, it’s difficult for our team to pinpoint the one most suited to yours, which is why our experts created a list that breaks down what to look for in the top eight-inch woofers.
Design and Size
We won’t elaborate too much on the size in this part of our 8 inch subs review, because the focus is on 8 inch options. The design is what’s important when you’re looking at a new subwoofer. Our team always suggests looking for one that’s a deep mount. Not only will this make installation easier, but it will also give you a sleeker look. However, you can also choose top-quality shallow mount subwoofers if you prefer clean installation. Our experts recommend a top mount depth of under 3 inches for the best and seamless setup.
You can also do more research and find car brand specific subs, meaning ones that were created for your vehicle model. This way, you can be sure the 8 inch car subs will fit into the cutout. The same logic applies and you should ideally look for a top mount depth of under 3 inches.
If you are choosing an 8 inch sub, this size category is already on the more compact end. The only ones smaller are the 6 inch options but they are less common on the market. Anything less than 6 inches won’t give you the bass you want.
Other common sizes of subs include 10 and 12-inch options but there are some that are 15 inches for heavy duty and larger vehicles. Our experts say that an 8 inch car sub is the best balance for everyday sedans. Not only do they fit within your car speakers system easily, bring about some awesome bass acoustics without taking up too much space.
The size matters in a subwoofer because the larger it is, the more power it can produce. However, since 8 and 10 inches subwoofer options are so common and relatively close in size, they can sometimes overlap in the power rating arena. A well-built 8 inch sub with a high voltage rating can outperform a poorly constructed 10 inch with a lower RMS.
Power
Speaking of power, it brings us to our next item on the list. Your audio system benefits from a sub because of the power it brings. You want a subwoofer that can deliver on the rumbles and thumps you get from your favorite tunes. For loud bass from your subwoofer, the power rating is your best friend.
The power rating of a subwoofer is split into two categories, just like speakers, they are the max power (e.g. Peak power for Skar Audio is 800 watts) and the watts RMS. The max power is the figure at which the sound system can be played at full volume for short periods. This figure is often much higher than the RMS, but our experts do not recommend playing your songs at this rating for risk of blowing them out.
The watts RMS is usually at least half of the peak power – the amount of power a subwoofer can handle continuously is what you should play your audio system at consistently. This is the safe number rating that can ensure your speakers are safe from damage over long periods of playing.
Sensitivity
The sensitivity rating helps your subwoofer achieve loud booms. The sensitivity can be considered the efficiency, and a subwoofer with a high sensitivity rating will require less power to play at the same volumes of a speaker with a low sensitivity. Subwoofer and speaker sensitivity is measured in decibels, or dB, and the higher the number the better.
Type
The best 8 inch subwoofers are split into different categories as well. Our team will address the most common ones starting with component subwoofers. A component sub is the basic subwoofer all by itself without an enclosure. A component subwoofer, like many of the ones on our list, are optimized to work with a type of enclosure, which we will cover in detail in a bit.
Since a component sub is essentially just the sub itself, it won’t have a built-in amplifier, which means you will need an external one. Who benefits from a componen sub? If you are a bit of an audiophile and want to create your own customized system, then a component subwoofer is the way to go.
Component subs offer more customizability, freedom to upgrade different parts and can be a part of a more impressive sound system.
There are also subwoofers that come with their own enclosures, and we refer to them as enclosed subwoofers. They’re not much different than a component sub and the only difference is it comes mounted and ready to go. This saves you the trouble of having to find a compatible mount if you don’t have one and reduces the time you spend building the system.
An enclosed sub will provide less bass than a component sub, so they are meant for people who aren’t too picky about the bass. If you are someone who isn’t well-versed in sound systems and don’t have time to build one from the ground up, then an enclosed sub is the one for you. An enclosed sub isn’t a powered or active one, so you may still need your own amp
That brings us into the next category of powered or active subs. The easiest car sub option for those that just want an all-in-one sub system that is simple to set up, then go for one of these. 8 inch subs that are active have the subwoofer and the amplifier rolled into one product.
Having the amp and sub together means you won’t need to spend time searching for a sub with the same power handling as your amp to ensure compatibility. Powered subwoofers are usually larger and heavier than the above options and greatly decrease the flexibility of placement for the different components.
Then we have the car model specific sub options that still bring excellent bass sound. These are the ones that are the least customizable as they are designed for your specific vehicle. On the plus side, you won’t have to worry your new sub won’t fit into your car as they are made specifically for you.
Amplifier
We mentioned amplifiers more than a few times and you may be wondering what that is and how to pick one. You have to be sure the one you choose has a compatible power rating with your sub.
Once you know how much power you will need, it will be much easier to pick the right amp. For standard bass systems, one or two channel amplifiers will do.
Voice Coils
The voice coils in the sub have often come up in our article today, and while they don’t have much to do with the sound production, it does have a big role to play in the durability and construction of the sub.
It provides the force powered by the magnets in your subwoofer cone. You may find solo designs or ones with dual voice coils. It’s common to find dual 2 ohm voice coils or ones that are 4 ohm, 6 ohm or 8 ohm of impedance.
Dual 2 ohm voice coils are a great starting point for anyone looking into a new sub for their car and our experts have found that a copper voice coil is best for longevity.
Enclosure
We mentioned that our experts would get into the type of enclosure commonly seen in an eight-inch sub or even among the best fifteen inch subwoofers. The enclosure is basically the housing for the component speaker. There is two main enclosure type, sealed and ported.
Sealed enclosures are a tight fit around your subwoofer and are the better choices for a high-quality bass sound that is very precise, clear, and crisp. They provide great frequency extensions and have very high power handling, and provides an excellent bass response.
When picking an amp for an enclosed sub, make sure you choose one that can handle high wattage.
You then have the ported enclosures that will typically provide more powerful bass sound at any volume compared to sealed ones. So if you like heavy bumps and thumps, then a ported enclosure is the best choice for you.
You can have your pick of sealed or ported/vented enclosures when you pick a component sub because they are mostly optimized to suit both.
Frequency Response
The frequency response is another feature that is paramount to the bass sound. The frequency range is measured from Hz to kHz (e.g. 38 to 250 Hz, 50 to 250 Hz, etc.) This range gives you an idea of how long or how high a subwoofer or speaker can go. For speakers, you want the widest range possible. This will ensure it can produce the sound spectrum most accurately.
For subwoofers, you want to focus on the lower frequency response. Since a subwoofer is geared towards the bass tones, the lower frequencies are what matters most. Choose a sub with the lowest frequency limit.
Installation
Our team of experts insist on choosing a product that’s easy to setup. Skar Audio products are known for sound quality and their design simplicity, which makes them easy to embed into your vehicle.
The top mount depth is an important factor to pay attention to if you go for a component sub. The top mount depth should not exceed 3 inches if you want a sleek setup. Our experts have carefully chosen deep mount sub-options from many different brands to give you a wide selection.
The installation shouldn’t take more than 30 min at most to be considered easy to set up. This high number is just when you have to hook up the system to an external amp and place it in a separate enclosure. Because the eight-inch sub is so compact, you can place it anywhere and won’t take up much space in your car.
The placement matters during the installation because the sound quality for the subs you place under your driver’s seat will be different from your trunk’s sound quality. Our team says that under your seat is the best option for direct audibility and feel of the vibrations [1]. But for rumbles and echoes that can be heard throughout the car, placing the subwoofer in your trunk is the way to go. One of the biggest challenges of adding a subwoofer to a car stereo system is finding the perfect place to put them without sacrificing passenger or cargo space. JL audio specifically designed these super-thin subwoofers for music enthusiasts who would love immense bass but have limited installation spaces. One product is the JL Audio 8″ Single 4-Ohm W3V3 Series Subwoofer. This JL Audio also is a great value for money.
Price
The price of your car sub can vary from under 100 dollars to over 150. Of course, the best 10-inch subwoofers may be more expensive than 8-inch subs. There are a ton of aspects that can affect the price from something as insignificant as the high performance brand to the minute details such as the materials used.
Our team understands why many people tend to gravitate towards known brands, because their experience in the industry should speak volumes. However, that doesn’t mean you should write off newer or lesser known brands. They may provide you with a product of similar or better quality and a lower price.
Oftentimes, you end up paying more for the brand name than the product quality itself. To keep you from spending money on the wrong features, our team suggests focusing on the criteria in our buyer’s guide checklist and related posts.
Other factors that can influence the price are the inner parts such as the voice coil. If you have a dual voice coil design, chances are they will cost you more than a single voice coil due to the efficiency.
The materials used to make the cones will greatly increase the price as well. For example, injected resin cones will cost more than paper cones due to the high quality. Even the surrounds can affect the price. Foam surrounds are softer but rubber surrounds are more robust. A roll santoprene surround is an example of a rubber surround that is flexible for bass deliverance but sturdy enough for longevity.
Another item that will influence the price is the warranty. Some brands may require you to purchase an additional warranty if you want the components to be covered to extending the existing warranty will also cost you extra. More renowned brands such as Skar Audio, Boss Audio and Rock ford Fosgate among others will most likely equip their products with a 1-year warranty.
If you can find products that come with longer warranties or even lifetime warranties, then that alone speaks volumes about what you should expect from the bass sound performance of your subwoofer.
A period for no-hassle returns is always appreciated by our experts. Just in case you purchase a product that arrives damaged, is faulty, or the wrong size, you can return it without any questions asked. Looking for an outstanding product is only part of the consumer experience. You must also remember to protect yourself with buyer’s protection like a warranty and guarantee.
