Why you should purchase underseat subwoofers

You’re probably wondering why should install underseat subwoofers over the other types of subwoofers mentioned above. It really comes down to six things:
  • Space
  • Installation
  • Cost
  • Efficiency
  • Performance
  • Weight

Space

Underseat subwoofers do not have the same huge footprint that other subwoofers will have on your vehicle. You don’t have to sacrifice your trunk space or destroy your rear deck trying to install kick-ass subwoofers. If you want the best subwoofer you can get in the least amount of space, you should go with an under seat subwoofer.

Installation

Installing Under Seat Subwoofers is normally much easier than the other subwoofer options. These under seat powered subwoofers often times have amplifiers built into them. There’s no need for an external amplifier, but having one would give a nice boost. If you don’t want to run wires all over your car, this is a good option.

Cost

These powered underseat subwoofers are often much cheaper to install than other subwoofers because of the built-in amplifier. Professional installation for these subwoofers are cheaper than other subwoofers depending on your personal setup. You should seek out a professional for quotes on the installation of an underseat subwoofer. I personally had one installed in my car for just under $150, and although I didn’t get quotes, I think this is significantly cheaper than the cost to install a larger set of subwoofers.

Efficiency

Underseat subwoofers have much better energy dynamics than larger subwoofers. Because these speakers are not as large, they will not require as much power to be driven. Your alternator and battery will last longer not having to drive a huge speaker system, and you will save money on gas in the long run.

Performance

Underseat subwoofers have an advantage when it comes to performance…. sometimes. They have the biggest advantage for the person who sits right above the sub. Because this speaker is mounted below the seat, you can truly get a butt-rumbling experience while driving. If this is your desire, we think an underseat powered subwoofer will be a good addition to your vehicle.
 

Weight

Under Seat Subwoofers are typically pretty lightweight. This makes the subwoofers ideal for lighter cars where weight distribution is important. If this is important to you, you will know it.

Why you shouldn’t purchase underseat subwoofers

Underseat subwoofers are a great addition for many car audio systems. However, there are some drawbacks you should consider when deciding to purchase an underseat subwoofer. Here’s three things to consider before purchasing an underseat subwoofer:
  • Sound quality
  • Customizability
  • Location
Sound Quality
The biggest compromise you face when deciding to go with powered underseat subwoofers is that the audio quality is not the same as a large powered subwoofer.

Customizability

These subwoofers are not as customizable as their custom counterparts. Due to the location-specific installation, these subwoofers come with casings that are designed specific for that application. This will make a big difference to a very small group of people.

Location

The location of these subwoofers mean they fire upwards directly into a car seat. Subwoofers and most other speakers are directional, and they are not in an ideal position if they are mounted firing up from a front seat. You might be in the position where this is the only practical place to mount your subwoofer. If you are in that position, we still do recommend getting an underseat subwoofer.

Under Seat Subwoofers vs Powered Car Subwoofers vs Competition Subwoofers

Under Seat Subwoofers are fantastic for some scenarios, but fall short in others. Sometimes, you should opt for a larger subwoofer to get your desired sound quality. We generally group subwoofers into three categories on this website, Under Seat Subwoofers, Powered Car Subwoofers, and Competition Subwoofers.

Under Seat Subwoofers

There’s two types of under seat subwoofers. You can get them in powered and passive variations. In this article, we are focused on powered subwoofers. These subwoofers come with an amplifier in the speaker, and do not require an external amplifier to drive it.

These under seat powered subwoofers are not as loud as other subwoofers on the market, but they have a significant set of advantages. These speakers vibrate the seat they are installed under, which allow for a great thumping feeling from them, without the massive size of the other speakers.
These speakers are much smaller than a lot of other subwoofer options, which makes it ideal to install for a small roadster like a Mazda Miata. If space is a problem, we highly recommend going the under seat subwoofer route.

Powered Car Subwoofers

Powered car subwoofers are great for automotive enthusiasts who have the space. You will typically need a strong amplifier with these subwoofers depending on the ones you purchase.

When powered car subwoofers are installed correctly, they do generally provide for better bass than underseat subwoofers. This is because they are typically larger and have more sound reproduction power.
If you are not impressed with medium results provided by under seat subwoofers, you should consider purchasing powered car subwoofers or competition subwoofers.
 

Competition Subwoofers

Competition subwoofers are some of the loudest badass subwoofers you can purchase for your vehicle. You should purchase these instead of under seat subwoofers if you are looking for bass you can show off proudly. We don’t recommend these for the light-hearted. You will DEFINITELY need a strong amplifier installed in your vehicle to drive these things.

Conclusion

When choosing between a powered under seat subwoofer, powered subwoofer, or competition subwoofer, you should consider what exactly you are looking for.
If you are just looking to significantly improve your factory audio system with few modifications, we think you will enjoy under seat subwoofers.
If you are looking for something a little more serious that is more customizable and you have the space, we recommend you go with powered subwoofer components.
If you are looking for something that will create a category 5 hurricane in your vehicle and you have the money to spend on them, you should go with competition subwoofers.
