Factors to look for while buying the best under seat subwoofers:

Power

You may come across the term RMS and peak power when buying subwoofers. Most people are unaware of what it means. If you want a high sound quality without any distortion, then compromising on RMS is pointless. You must try to opt for at least 150 watts RMS; however, 300-watts RMS provides a much better audio output. In subwoofers, the peak power does not play as big of a role as RMS.

Enclosure

The metal enclosure plays a crucial role in protecting your subwoofer from the impact of rough rides. It makes your subwoofers damage-free and enhances the sound quality, which most people are unaware of. Enclosure type is also crucial; a sealed box is ideal for providing the most precise, deep, and grave sound. On the other hand, the bandpass and ported boxes are perfect for high volume. You can make a choice depending upon your music taste.

Subwoofer Size

Some people are concerned that a small subwoofer will not produce the correct output. Well, it may be true in some if you have a big vehicle or an enormous truck. However, subwoofers with suitable enclosures and good power can easily create the best sound. An 8 to 10-inches subwoofer is ideal for people who have an SUV, normal-sized truck, or a regular car.

Safety

If you are a rash driver, then the possibility of you damaging the subwoofer is uncanny. You must find a subwoofer that does not only have features to protect itself but the vehicle and a user. A metal casing is ideal to stop the subwoofer from getting damaged when driving in harsh conditions. The thermal and circuit protection features are a must to ensure the longevity of a subwoofer.

Final Verdict

Subwoofers are great for enhancing the sound quality of your car’s factory speakers. If you survey the market, you will find an exceptional choice. However, it is essential to buy subwoofers that fit your music taste, your car’s interior, and your budget. The best underseat subwoofers will be a game-changer for you as it amplifies the sound quality and intensifies the audio impact.
