Best Powered Car Subwoofers: What to Look For

It’s essential that you understand what you are looking for in order to find the best powered subwoofer for your car. You will want one that meets your specific needs for your specific vehicle. It needs to fit your vehicle, as well as your preferences. So take your time and select and item with care.

First of all, you need to look at the dimensions and measurements of the powered subwoofer. Make sure the product you choose can fit in your trunk or under the seat.   Take measurements to ensure that your car has enough space for the item you desire. If you are choosing a subwoofer for your trunk, you should have enough space no matter what you drive. However, if you are choosing a subwoofer that will be placed under the seat, you need to make sure there is enough height. This is very important if you have a car with power front seats, as these seats often have components underneath.

You should also be on the lookout for how much power the sub you choose can handle. This will be listed in watts and will give you a good idea of how much power the subwoofer can handle. The key thing to consider, since these subwoofers are already paired with an amplifier, is how powerful you'd like your system to be. The more power, the louder the system will be.

While we’re discussing power, be sure to keep an eye out for ohms. This'll indicate electrical resistance, or “impedance.” (It “impedes” the electrical flow.) Most subwoofers have 4-Ohms, but there is a vast variety of products available so finding the right one for your needs should not be a problem.

Before you install your subwoofer, you’ll need to know what type of enclosure it has. There are two common types, a sealed and a vented enclosure. Sealed enclosures are air tight and have a very basic design. Vented subwoofers, also known as “ported subwoofers,” have various vents that emphasize specific frequencies. Typically, sealed enclosures are better for small spaces like trunks or under seats. Ported enclosures are a great design for larger spaces.

The amount of voice coils will also make a difference. Voice coils give input to the speakers, and if it has one coil (know as Single Voice Coil or SVC), it will have one input that you need to wire. Dual voice coils, however, are popular among audio enthusiasts who want more options when wiring their system.

Finally, take into account the size of the subwoofer. While the enclosure will have its own measurements, the subwoofer inside the enclosure will effect how the speaker sounds. In most cases, the larger the subwoofer, the lower the frequencies it can reach.  However, larger subwoofers can't keep up with faster bass. This may be heard more in fast pace rock or metal music. If space is not a concern and you want the lowest bass possible, then a large subwoofer is your best option.
