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