3. Rockford Fosgate P300-12 – Best Self Powered Car Subwoofer
The Rockford Fosgate P300-12 is one of the best powered car subwoofers on the market. This is mostly thanks to the self-contained and all inclusive system that is very convenient. With this system, you will only need to run the power and ground and get a signal from your source.
The 12-inch cone in the Rockford Fosgate P300-12 is one of the largest on our powered subwoofer review and it displaces a lot of air. This allows it to produce a deep sound that few car subwoofers can rival. But, there is also a 10-inch option for motorists that may prefer it.
Furthermore, the 300 Watts class D amplifier does a good job powering up the unit, and there are no overheating issues even when used for an extended period.

The Kicker 11HS8 is one of the smallest powered subwoofers in this review. It is just a little over 3 inches high and about 14 inches long. These dimensions make it easy to hide away, and it will be perfect for under car seat installation.
This unit rocks a smaller 8-inch woofer cone, but despite its small size, it still manages to output a more than average sound quality.

At only 13.5 inches long, this is another super compact powered subwoofer that will be perfect for anyone that does not have a lot of room under or behind the car seat.

9. Klipsch R-10SW – All-Digital Amplifier
The all-digital amplifier is the start of the show for the Klipsch R-10SW. It is also one of the key reasons it is one of the best powered subwoofer with a built-in amplifier.

10. Yamaha NS-SW300PN – High-End Powered Subwoofer
The high-end look of the Yamaha NS-SW300PN is the first element that will draw many people to it. But, the good news is that it also performs as good as it looks if not better.

How to Buy the Best Powered Car Subwoofer
Before purchasing a powered car subwoofer, here are some important factors that you need to take into account.
1. Power Handling
The power handling gives you a good indication of the loudness of the woofer. In general, the higher the power handling, the louder you can expect the woofer to be.
However, power isn't everything. For the best sound, the amplifier needs to be powerful and efficient enough for the subwoofer.
With these subwoofers you can get model with up to 800-watt maximum power output like Rockville RW10CA, but anything that can handle at least 150 watts should be good enough.
2. Enclosure Design
The enclosure design affects the sound of the woofer. In general, a closed loop design tends to give the best bass effect.
Another option is to place the woofer under a seat for better bass reproduction. Of course, this is only possible for models that are compact and have a low-profile.
3. Cone Size
For a punchier bass, 8-inches powered subwoofers are amazing. But, keep in mind that the larger the cone the pricier the subwoofer tends to be. A larger one also leads to a larger housing, and hence making the subwoofer bigger.
4. Sensitivity and Impedance
Sensitivity is an important aspect of a woofer. The higher the sensitivity of the powered woofer, the more efficient you can assume the woofer to be as it responds to lower power to produce the same sound.
The impedance is another important factor to consider. What the impedance shows is the type of audio wire you can use during installation.
A woofer with a rated 2 Ohms impedance can be connected with a much thinner wire than a woofer with an impedance of 8 Ohms.
5. Tuning Options
For more versatility, look for powered woofers that provide the ability to fine-tune the sound. They usually have the bass boost EQ and low pass filters at the back.
Moreover, many top-rated powered car subwoofers can even be remotely controlled for even more ease of use.
There is at least one powered subwoofer model on our list that will work for you regardless of your preferences.
However, for anyone shopping for something more affordable that still delivers an excellent sound quality and is well built, the Rockville SS8P is our recommendation.
That said, the Rockville RW10CA is our best overall model thanks to the higher 800-watt power output, high level inputs and amazing controls.
