Best Under Seat Subwoofer Reviews

Not enough space in the trunk for your preferred sub? Well, you don't need it, nor do you need to settle for your factory speakers, because now you have under-seat woofers.

These are moderately priced and can give you the best audio experience possible. So, make your car sound system complete with the resonating bass effects.

With that said, not all products come alike, some might not come with all the wires and components needed or some might. But don't let that cloud your judgment, because you can get those additional items easily.

So go for the best under seat subwoofer without worrying about peripherals, as we guide you through the process.

How Do You Install a Powered Subwoofer?

Powered subwoofers usually come with enclosures and amplifiers. Depending on your level of expertise, you should check whether it comes with an amp or not.

If you're more of an amateur, then you should choose a sub that comes with an amp because when you need to purchase the amp separately, it usually requires more wiring. So, inexperienced people will prefer subs with a built-in sub.

Without further ado, let’s look at the process of installing a subwoofer.

Step 1: Specifying the Spot to Mount the Woofer

Remember that the sub will heat up at some point, so there should be space for ventilation. Moreover, if the place is too tight, it might become difficult to reach.

So, if it fits, then under the seat is a good place to mount the sub.

Step 2: Acquiring the Wiring Kit and Fuses

When you buy the woofer, you won’t get the needed wires and fuses. So be sure to buy those separately. Thereby you should buy the amp wiring kit.

Step 3: Connecting Battery and Subwoofer

Before you start, remember to disconnect the battery. Do not start working before it.

Next, use the power wire to connect the battery and sub. If your fuse isn't assembled, then slit part of the cable so that it covers the distance between the fuse holder and the battery. After doing so, cut the insulation off the ends of the cable.

Similarly, cut the insulation of the amp cable. Cut only the end that goes into the fuse.

Press together the terminal ring to one end and fuse holder to the other. Next, connect the amp cable’s end to the fuse holder.

Step 4: Passing the Power Cable 

Once the battery end of your work is done, you need to pass the power cable into your car. Usually, there are holes present for entering. Use those and enter the car’s cabin.

Then again, once inside, put the wire under the carpet along the corner, so that you don’t have to step on it.

Step 5: Turn-On, Signal and Ground Wire Connections

Your next step is to run the turn-on wire and the RCA signal cable. Use the opposite side of the power cable to bring this to your stereo. Both of these are to be attached to the radio of your car.

Use the manual to see which outputs are used for the cables.

Now the ground wire needs to be in touch with the car's bare metal. Connect it to a bolt that is on the ground.

Step 6: Mounting and Connecting to the Sub

So all that's left is connecting the appropriate wires to the sub. Afterward, reconnect the battery, and you are good to go!

What to Look for Before Buying?

After reading our under seat subwoofer reviews, you must have some favorites already. But how to pick among them?

Below, we are going to talk about some features that will help you to make a pick between them.

Power

The more power the woofer has, the better the bass you will get from it. There is nothing simpler than this.

But most people don’t need glass shattering bass, so they can make do with normal bass as long as it sounds melodious.

Still, check the RMS instead of the peak power. RMS determines the overall functioning. So, the more the RMS, the better the chances of it handling the sound.

Having more power means it can convert more electric energy to sound. Hence, more power means more sound.

Frequency

The frequency range indicates what you hear. The more the range, the more clarity you get. Without a wide range, you will not be able to hear the lows well.

So for people who like their audio to be pitch-perfect, they ought to check the frequency.

Size of the Enclosure

For under seat subs, the greatest advantage is you get to keep the enclosure within your car. Most car subs are either free air, or they are placed in some awkward position.

But under the seat is their rightful position. So, keep the size of the seat in mind when buying the subs, as space determines what height your sub should have.

Also, the spacing varies for different cars. Sports cars have really low seats, so there isn’t much space underneath. Trucks and cargo vehicles have enough space to mount to subs under it if needed.

Enclosure

This is not that big of a concern if your car has a slip-resistant carpet or mat. But to avoid uncertainties, good subs come with a scratch and slip resistant boxes. 

Amplifier

Subs that come with amplifiers are always more popular. They save you plenty of wiring work. Also, buying amps separately will cost you more.

Besides, if you aren’t an expert on the subject, you will also lose sleep over it because this comes with a lot of additional questions like which amp to buy or what wirings are needed.

Construction Material

You’re not supposed to understand a whole lot about it. But the gist of it is, a sub with a good magnet and cone means the product is there to last.

However, you may find cheaper alternatives, but that won’t matter if the product collapses within days. So check whether they have used a good magnet, voice coil, and cones.

Further, the material of the enclosure needs to be sturdy because your ride might get bumpy at times, and it has to be strong enough to protect the sub.

Sensitivity

The more sensitive the sub is, the less electricity it will require to produce sound.

So the higher the sensitivity, the better the chances of the product's stability. Because when it will need less electric energy, it will also not wear out the sub much, and it will not heat up easily. Therefore, it can be used for a longer time.

Easy Installation

Installing a sub becomes extra troubling because you have to do it in such a closed space. Therefore, the inputs on your sub should make it easier to install by being visible.

Also, most accessible options should be on the side panels where it’s easy to reach.

Price and Brand

Buying the product of a renowned brand is always a safe bet, but if you’re unwilling to spend on it, then you should remember how tedious the process can get.

Therefore, don’t buy something without properly checking.

Underseat Subwoofer Vs. Trunk Subwoofer

Whether you place it under the seat or in the trunk usually depends on your car’s accommodation. However, if you’re open to both options, then it might turn into a dilemma.

Underseat subwoofers are recommended to people with smaller cars who do not have space in the trunk. The reason behind that is under-seat woofers are not as powerful as the trunk ones. So if you have space, then you might want the only that will give you more sound.

One recurring problem with under-seat ones is it becomes uncomfortable when it’s under you. When your woofer is bigger, then it becomes even more difficult to sit.

Furthermore, keeping it under the seat is also sometimes unsafe. Unsafe for the sub as it doesn’t have much room for ventilation. Also, it may heat up. Alongside that, durability comes in too. Trunk subs are seen to be more durable.

However, although trunk subs give you more power and clarity, they are also more expensive. For subs, it is an obvious thing that more power means a higher price.

But if budget isn’t a constraint and you prefer very loud and clear bass, you should always go for the trunk subs.

Besides, you have more mounting options for trunk ones, and you can easily do the wiring work as well.

For bass specifically, though, the under-seat subwoofer should be more than enough if you are not a huge fan of loud music. The under-seat subs may have less power, but within the small boundary of a car, it should be enough for most people. 

So if you are a small car owner with no trunk space, don’t be disappointed because you probably don’t need the big sub anyway.

But for bigger cars or cargo vehicles, the trunk woofers seem like the better choice.

Frequently Asked Questions

1. Which subwoofer gives the loudest oomph?

The sub that with the greater power should give louder bass and oomph.

2. If I want my windows to shake, what sub should I buy?

This depends on size, power, and sensitivity. The size here is the size of the enclosure. With a bigger box, you will get louder and deeper bass.

3. What features to look into if I want a clean sound?

For sound clarity, check the frequency range. A wider range means you will be able to hear the highs and lows with more clarity. The richness of sound also depends on the enclosure.

4. Does the quality of the amplifier matter?

It matters when it comes to your subs lifespan. Better amps mean your sub is having an easier time. It won’t heat up easily nor wear itself out. So a good amp is essential if you want the woofer to be in good condition.

5. What is the first thing to check when buying under seat sub?

The obvious answer is to check the accommodation of your car. If that is not a concern, then check the power and ease of installation.

Final Words

Buying the best under seat subwoofer is no easy task, especially when the concern is even with whether to buy one or not.

With options like free air and trunk subs, deciding on one is tricky. Hopefully, the decision became easier with this review.
