Driver Size: The overall size of the subwoofer is probably the only factor that will give you the right idea about its installation as well as performance. And this size also means the diameter of the primary driver apart from the physical size of the unit. Regarding subwoofers, a larger driver is always better as it can produce a stronger bass output. Wattage Rating: Another factor that directly affects a subwoofer’s performance is its power output rating. The peak power rating is the maximum power output available from the subwoofer. So, a higher peak wattage rating means you will be able to use the subwoofer at louder volumes. Along with that, you should also check the RMS power rating since the peak power rating is momentary. Subwoofer Impedance: The impedance rating is something that you will find listed alongside almost all audio output devices, whether it is a powerful gaming headset, an audiophile open-back headphone, or a subwoofer. This impedance simply means the electrical resistance inside the speaker circuitry and it is also counted in the Ohms unit. If you are planning to use the setup with an amplifier, you should pay even more attention to this factor.
Today, we are going to talk about the best subwoofers you can possibly find on the market right now. As there are many different models available out there that vary in terms of power output capacity, size, frequency response, etc, it can get quite difficult to find the right subwoofer for your car, especially if you are looking for a compact option. To help you with that, we have shortlisted the best options that are powered by an 8 inch driver.

Buying Guide For The Best 8 Inch Subwoofer
A subwoofer is slowly becoming more of a necessary audio equipment than a luxury addition to a sound system, especially after the recent rise of bass-heavy music which almost everyone loves to listen to. If you also like to play loud music in your car, you should consider installing an 8 inch subwoofer in your car right now. Today, you will find the best options available out there for an 8 inch subwoofer so that you won’t have to browse through hundreds of pages to find the right option for your car. But, if you are not sure how to pick up the right option that suffices for all your output requirements, worry not. We also have a buying guide for the best 8 inch subwoofer ready for you. In this guide, we will talk about some important features of an 8 inch subwoofer so that you can easily choose the right option for your needs without much trouble.
1. Power Output Capacity
The power capacity is a factor that you need to check irrespective of the type of audio hardware you are buying. You will need to ensure that you are buying the right option for your car whether you are buying a speaker system or a subwoofer alike. There are 2 different power ratings that are usually listed with a subwoofer that are RMS power rating and peak power rating. The RMS or root mean square power rating is the average power output capacity of the unit at which it will be functional at all times. However, this is not the minimum power rating so do not get it confused. On the other hand, the peak power capacity is the maximum wattage output a subwoofer can offer, and it is momentary. It means that the speaker won’t be functioning at peak power capacity at all times.
2. Sensitivity
The sensitivity is yet another crucial factor of a speaker, more importantly, a subwoofer, which directly affects its overall performance and output level. To put it in simple words, the sensitivity of a subwoofer refers to its property of converting electrical power into sound. As you can imagine, the sensitivity of a subwoofer is offered in dB units, which is what we use to measure sound levels. To put it in comparison, a subwoofer with a higher sensitivity is much more efficient than those with a lower sensitivity rating. This is because a high-sensitivity subwoofer can create a certain sound level without needing as much power as a low sensitivity subwoofer. So if you are looking for a value-for-the-money option for the long-term, consider investing in a high sensitivity 8 inch subwoofer.
3. Frequency Response Range
While the factors we have seen so far tell you about the output capacity of the unit, the frequency response range on the other hand is a factor that will give you an idea about the output quality of the subwoofer. This is also somewhat similar to the sensitivity of the subwoofer, but it only deals with the performance of the primary driver based on the input media signal. As you may already know, the sound is a wave and it is measured in Hz units. So, the frequency response range basically tells you the highest and lowest frequency that the driver can handle and everything in between. If you are buying a subwoofer, your main focus should be towards the lower end of the response range since it deals with lower frequencies, i.e., the bass. If a subwoofer can offer a response to a low-frequency value such as 30 Hz or 20 Hz, it means that you can get a pretty strong bass response from the system. As we are discussing 8 inch subwoofers, you can easily find options that offer frequency response to as low as 40 Hz signal with ease.
4. Impedance Rating
The impedance is one of the factors which is usually ignored when purchasing audio hardware, especially a subwoofer. But keep in mind, this is the only factor that can change the compatibility of the subwoofer with your system. As we mentioned before, the impedance rating is basically the electrical resistance of the internal circuitry of the speaker and you need to keep it in mind when you are pairing it with an amplifier. To allow an efficient power supply to the subwoofer, a lot of these options will have to be connected to an amplifier. And if the impedance rating of the subwoofer is not identical to that of the amplifier, you cannot expect the subwoofer to perform at its ideal power capacity. If a subwoofer has a higher impedance rating, it means that it requires more power to perform at a particular level since there is higher electrical resistance inside the circuit. So, you will need an amplifier that can compensate for the resistance and offer a uniform power supply.
Conclusion
There are many options available on the market right now for a car sound system and most of these options offer a minimalistic bass response. This is because of the lack of a dedicated subwoofer in the system. In such systems, the bass response is created by the primary drivers which are not even nearly as powerful as what you will get with a dedicated subwoofer. So, you should consider going with a powerful dedicated subwoofer if you want a strong bass response without losing on the output quality of the unit. And for that, we have prepared this helpful list of the best 8 inch subwoofers available on the market right now. In this guide, you will find all the necessary information about an 8 inch subwoofer along with a buying guide to help you pick up the right option based on your needs. We also have some handy recommendations for you right here so that you can easily make the choice without much trouble.
If you already know that basic subwoofers are simply not good enough for your listening experience, then you should go with the Planet Audio 8 Inch Subwoofer. Despite being a similar option to other subwoofers on this list in terms of size, this subwoofer is backed by a peak power capacity ranging up to 1200 Watts. It also has a dual voice coil for clear and sharp audio response with a 4 Ohms impedance rating. The lower frequency response for this subwoofer is 39 Hz, ensuring a string bass. But, if you are looking for a cheap yet reliable option, we will recommend the Pyle Car 8 Inch Subwoofer. Since Pyle is already a well-established brand on the market, you will find this subwoofer suitable for the long term. And when it comes to power rating, the Pyle Car Subwoofer Audio Speaker certainly does not disappoint with up to 800 Watts peak power capacity. It is equipped with a 4-layer 1.5 inch single voice coil that also ensures decent protection against environmental problems. While we are talking about long-term options, you should also check out the Rockford 8 Inch Subwoofer before you make a choice. This is one of the premium alternatives on the market for an 8 inch subwoofer that offers up to 500 Watts power rating and operates at 2 Ohm impedance. The power impedance rating makes it easier for you to find a compatible amplifier for the subwoofer. It also comes with a diamond-cut cast aluminum trim ring which makes the installation much easier.
