What to Look For Before Buying the best underseat subwoofer under 200
You won’t get a subwoofer under seat, which is best in every aspect. But what you can do is trying to look carefully at every feature to find the best under seat subwoofer based on your car requirement. Proper subwoofer installation is also mandatory to get better performance. We are mentioning some crucial points below, which you must consider before purchasing the best parts.
Powerful subwoofers have high-wattage powers. The more powerful it is, the louder music you can play. But you need to remember; it will cost you additional money to buy high-power items. On top of that, they consume a higher level of energy than standard wattage ones.
You need to remember two things for the power of subwoofers: RMS power and Peak power. RMS power means the average audio makes with its overall capacity.
On the other hand, peak power implies the maximum possible sound a subwoofer can go.
Maximum Sensitivity Level
Another crucial point is the sensitivity level. A power base will not make quality sounds unless it features a high level of sensitivity. Additionally, it is another parameter to define how loud it is. You can compromise a little wattage power if your car underseat subwoofer has the right level of sensitivity.
Choosing between passive or powered
An under seat part either comes passive or powered option. A passive one collects power from external sources, and this type of unit is known as an underseat amplified subwoofer. It is a low-cost option, but you need to make sure the amplifier is compatible with your vehicle.
On the contrary, a power base product is more convenient to use since most of them come with inbuilt amplifiers. Also, you don’t need additional accessories, and it can save some space in your car.
Sealed or Ported Enclosure
A sealed product comes with a sealed box, which lacks free airflow. It needs more power to produce the same level if you compare it with a ported subwoofer. On the other hand, a ported item has a convenient design with a larger cabinet to promote airflow.
The design has a direct impact on producing decent quality sound. Ported subwoofers are the best option for deep bass with an impeccable depth. However, you can experience accurate sound with sealed box ones.
Sound range or frequency range means the ranges of audio your under seat subwoofer will produce. A lower-frequency range is more effective to enjoy high-quality sound. However, make sure you don’t depend on only this feature since the results may vary from sub to sub because of other specifications.
Single or Dual Voice coil
Most subs under seat come with a single voice coil, which comes with only one piece of copper wire around the former, and it makes the right level of sound. While dual voice coil wraps two lengths of copper wires around its former and it is a top favorite among car lovers as it provides high flexibility to make it compatible with car audio systems.
Many good-quality subwoofers make incredible car audio with high power and sensitivity levels though their size is compact. However, when you want to achieve low-frequency sounds, go for a minimum 12 inches subwoofer as you need higher energy for low-end ones.
