The Kenwood KSC-SW11 is a popular solution for car owners on a budget. This model is an all-inclusive solution that packs a powerful 150 Watts pre-amp that powers an 8-inch cone. Since the cone is small, it vibrates more and produces a punchy bass that is harmonious.

How to Buy an Under Seat Car Subwoofer

How to Buy an Under Seat Car Subwoofer

Before you can get the best hideaway subwoofer for the money, there are some important factors to consider. Here they are:

Power Handling

If you want a deeper bass, a higher power handling by the under seat woofer is preferred. The subwoofer needs to have enough power to convert electrical energy to sound energy. The higher the power rating, the more sound energy it can potentially transform.

Amplifier

Almost all under seat subwoofers for cars come with a pre-built amplifier. Most class D amplifiers should be efficient and powerful enough to handle an under seat subwoofer. Additionally, take note of the power rating of the amplifier. The higher the better, of course as it will play louder.

Cone Size

The cone inside the subwoofer is the part that displaces air to produce the bass sound. The larger the cone, the more air it will displace. Therefore, choose a model with a bigger cone if you want a deeper and more powerful bass. As an example, a 12-inch model will always produce a more powerful bass than an 8-inches model, no matter how good the 8-inch sound.

Sensitivity

A subwoofer that is more sensitive will require less electrical energy to move the cone and produce a sound. Therefore, such a woofer is considered to be more power efficient than other models. Moreover, since it consumes less, it will also last longer since the components will heat less and are more durable over time.

Impedance

If you want a clean install and do not want audio wires to be visible, then you must use thin wires for the connections. However, only subwoofers with a low impedance will accept thin wires. For discreet installations, a 2 Ohms subwoofer is always better than a higher impedance model.

Resonant Frequency

The resonant frequency is the minimum frequency the subwoofer can respond before it distorts. Lower is better in this case. Especially since an under seat subwoofer will be in a confined space where it is more prone to distortions. A lower resonant frequency should help massively in producing a clearer and cleaner sound.

Conclusion

We've discovered that there are several types of under seat car subwoofers that vary in size, shape, and price. If you have a small car and still require a decent bass, this type of subwoofer will definitely fit the bill. Don't let its low-profile and compact form factor fool you. They are quite powerful.

However, keep in mind that the best under-seat powered subwoofer does not have to be the most expensive one or have the biggest cone. Choose one based on your preference, budget, and need.
