Rockville RW10CA
The RW10CA goes in a low-profile enclosure. It’s a powerful subwoofer that has 10 inches in diameter. With its slim design, it will work great for any vehicle as it fits in limited spaces. This way, it can even work as the best underseat sub for a truck. The housing of the sub is made of plastic that can’t provide superior durability.

The RW10CA is an active subwoofer, powered by an amplifier that uses PWM MOSFET power supply. With 800W of power (200W RMS), it’s powerful enough to provide a punchy and mighty bass without sound distortion. It will enhance your music and improve your audio system.

All the connectors and control elements (frequency adjustment, bass boost, etc.) can be found on a special panel on the side of the subwoofer which allows for increased convenience. This means that you will be able to tune the sound in accordance with the music genre and your personal preferences.

Pros

  • The circuit has overload protection.
  • The high level input frees you from the necessity to remove a receiver when installing an amp-subwoofer combination.
  • With 98 dB of sensitivity, the sub requires minimum power to play at the loud volume level.

This 10-inch Pioneer is the last model that is good at delivering deep and flawless bass.

This 10-inch Pioneer is good at delivering deep and flawless bass. The design relies on a rigid cone surface that promotes better air movement resulting in clearer and noise-free sound. The peak power of 300W is another distinct feature of this Pioneer subwoofer that offers an incredibly rich and accurate bass response at any volume level.

The enclosure is made of injection-molded resin that adds more stiffness and durability to the structure. The Pioneer’s surface has an anti-scratch non-slipping coating that makes it possible to install it in any place. This Pioneer is mostly designed to be installed under the seat of your car. Its small dimensions do not need lots of space and make the sub fit to any location.

I recommend purchasing this product if your car is not big and has an extremely slippery interior because this Pioneer model is the only subwoofer that can handle such a problematic surface successfully.

  • Good bass when you turn on the radio.
  • Great for low-end bass.

Cons

  • The unit cannot be installed in places that can be affected by vibration.

This 600W (150W RMS) sub is supplied with a powerful built-in amplifier that produces a satisfactory, tight, booming bass. Plus, it has plenty of features for sound customization.

All the controls and ports are located on the dedicated panel on the subwoofer’s side that will protrude from under the seat. This facilitates both the setup process and the use of the subwoofer.

The sub comes with a special installation kit, so you will get everything you may need for installation. The outer part of the provided wires is flexible and resistant to extreme temperatures.

This 10-inch underseat powered sub is another worthy option you may like. It is no way inferior to other alternatives here. With the peak power of 200W, the Cerwin delivers exceptional bass performance backed by innovative features put at the core of Cerwin design.

The subwoofer is handy and simple in use. The remote control allows tuning the sound while driving. The adjustment involves changing the parameters of input insensitive, volume, and frequency. The 180° phase control switch helps the listener choose a suitable position to achieve the most comfortable listening experience.

All these characteristics make this Cerwin model powerful and capable of generating loud and accurate bass sound in a car.

Buyer’s Guide

How to Determine the Best Subwoofer for Your Vehicle

Most of the options on the list are attractive and similar in specs. If you are on the fence, there are a number of criteria you can follow to define your best underseat subwoofer.

Size

Before choosing a subwoofer, I recommend measuring the space under your car seat. Since these devices differ in thickness, you need to be sure that it perfectly fits this gap. If you prefer mounting it in the truck or somewhere else because your vehicle is large-scale, you can go for any model without hesitation.

Installation

The installation commonly boils down to the correct wire connection. To handle it successfully, you need first to choose the right subwoofer size. Then, place it under the seat so that the ports remain accessible because you will need to use them later to connect speaker and amp cables.

Power

Each subwoofer has a peak power. The higher, the richer sound you will get. If you are satisfied with standard sound power, the peak power of 150W is normal. If the deep sound is your priority, look for options with peak power starting from 200W.

Type of Control

I vote for remote control obviously. When you are on the road, the last thing to care about is pressing the buttons on your subwoofer to make it sound better. Wired devices are standard and less expensive, but the remote control feature allows you to feel free while driving because it can turn on and off automatically. This makes you less bothered and more focused on staying vigilant about driving.

How to Install an Underseat Subwoofer

There are a few simple steps to install a subwoofer under your seat.

  1. First wire the power from the battery. Make sure you do not mix up the battery with the fuse box.
  2. Next, connect RCA cables to the back of your sub.
  3. Configure the remote activation of the wire so that it starts automatically with the amplifier.
  4. Place the device under the seat.
  5. Wire up the amp.
  6. Connect the power cable to the battery.

When wiring the subwoofer, make sure that the “+” from the amp is hooked up to the “+” on the speaker, and vice versa.

Which Subwoofer is Better – Underseat or Trunk?

An underseat subwoofer is usually seen as more advantageous because the driver has a deeper and louder sound in their cabin. However, there are a number of weaknesses that can make you rethink your decision in favor of a trunk subwoofer.

Trunk subwoofers have more customization options so that the listener is able to set up the sound to their liking. Normally, the trunk exposes this device to fewer risks and threats because of less vibration taking place there while the driver is on the road. Since a trunk subwoofer comes in a larger variety of sizes, it can fit both large-scale and small vehicles. In terms of performance, it produces much more accurate and earth-shaking bass that is closer to perfection.

Nevertheless, the underseat subwoofer excels in other aspects. For instance, they are lightweight and portable, which means that you can carry them wherever you are headed for. The underseat subwoofer is not as pricey as the trunk one and therefore more affordable to lots of buyers. It also takes less time to install it in a car. On the contrary, the installation of a trunk subwoofer is a complicated and time-consuming process. Finally, the underseat subwoofer is the only possible option for small car owners because it requires a little space and can be mounted in vehicles of any size.
