Things to Keep in Mind While Choosing Best Under Seat Subwoofer

As we said earlier in the intro portion, all the under-seat car subs are not designed equally. So it is going to be very difficult to choose the right one. But when you know exactly what you are looking for, then things become straightforward. 

So have a look at some top traits which you have to consider while making a purchase decision. If you follow our buying guide for the best under-seat subwoofer, then you are going to appreciate your decision. 

1. Power

When it comes to purchasing any electronic device, the power factor is always the priority. Only the most powerful devices are efficient to fulfill your needs. The under-seat car subs contain several power factors to keep an eye on while shopping. 

First of all, you have to choose between active or passive subs. The active under seat subs don’t require any other amp to produce music and are powerful enough. 

On the other hand, the passive subs work with a separate amp, which is a bit costly. Now the thing is that you have to find a compatible kit when you are going with a passive car sub. 

May you have seen that many passive models produce sound distortions. It is because the amp produces more power than subwoofers and damages the sound quality. 

But still, if you want to vibrate your neighbor’s window with your car music, then passive subs are your desired option. 

Furthermore, you have to look for RMS power too while choosing a passive mini subwoofer for your car. 

2. Size

We are talking about under seat car subs; then, the size factor is crucial to look for. The size of the subs also affects the installation process. 

It is better to go with a compact subwoofer, which doesn’t have too many wires for easy installation. The 10 inches subwoofers are the most common size and able to produce appreciable sound and bass. 

If you have a big car like an SUV or Sedans, then you may go with 12 inches models. It will fit under your car seat comfortably without any problem. 

3. Easy to Use and Install

The most important thing is, if you are avoiding bigger car stereo systems and going with a slim subwoofer under the seat, then you may desire an easy-to-use device. 

In these terms, you have to look for a car sub, which requires less or no wires to be installed and doesn’t require any specific engineer to install it. 

Furthermore, you shouldn’t need to struggle with pressing a button below your seat. The onboard control devices are much straightforward to use and control. 

Final Verdict

All the models listed in this buying guide are durable enough and the best in the market. We have chosen these models by keeping an eye on the important traits we have discussed.

 Without any doubt, we can consider the Rockville RW10CA 10″ subwoofer as the best under seat subwoofer on our list. However, other models are also excellent enough in their own space. All the models on our list are easy to install and control and produce clean, crisp, and high-quality sounds.
