Things to Consider Before Buying Under Seat Subs

Like any other item, you must be aware of a checklist of factors before making a significant purchase. Once you’ve chosen the type of subwoofer that you wish to buy, comparing a few factors can aid in the process of deciding. We are going to steer you through the most crucial aspects to consider when purchasing this item.

Here are a few points you should be concerned about when purchasing subwoofers for under seat use:


First, it is crucial to think about how much power as well as wattage you can get from the subwoofer you’re planning to purchase. Because bass demands a lot of energy, a higher wattage can provide this energy regardless of volume. When it concerns power, there are two factors to consider:

Power of RMS: which is a part of the overall power output in a moderate amount.

Power peak: which will be the loudest that your subwoofer can be.

It is advised to be more attentive to RMS and select an amplifier with a wide power range between RMS and peak RMS power while aiming for the maximum wattage your budget allows. When you follow this advice, you’ll be able to enjoy the crisp and clear sound, regardless of the volume of your music.

It is essential to make sure that your sub’s power is compatible with the capabilities of your amplifier. A high RMS value is useless in the event that your amplifier doesn’t match or exceed it. If there is an amplifier that you are using externally, however, ensure that they are compatible. The ideal is for the amplifier to be within 75 to 150 percent of the subwoofer’s power handling capabilities.

If you don’t, you’ll risk the distortion of sound – and even permanent subwoofer damage.


If you’re looking for a tidy installation and don’t wish to have audio wires apparent, you should utilize thin wires to make the connections. However, it is essential to note that only top-rated car subwoofers with low impedance can be used with small cables. A 2 Ohms subwoofer will always be better than a model with a higher impedance to make your installation more discrete for quiet installations.


One of the most significant factors to bear in mind is size; for that, you’ll be looking at your vehicle. Subwoofers for under seats generally are available in sizes ranging from 8 to 12 inches. The larger subs can be more challenging to put underneath your seat. This is the reason many opt to place them behind their seat.

Size affects performance. The larger the base unit, the greater the power it will handle, and a higher power handling capability means more excellent bass and volume. It’s no surprise that a larger sub is likely to be more expensive too. The size you pick will depend upon your financial budget, space in the car, and so on. There isn’t any proper or incorrect size since it is dependent on the particular situation.

Powered or Passive

Powered subwoofers typically have built-in amplifiers. This means you’ll ultimately save space without losing the power of the sound output. In addition, subwoofers powered by electricity are incredibly effective for mid-range frequencies since you don’t need to spend much time matching the amp and subwoofer characteristics.

Passive subwoofers tend to be fundamental units inside the enclosure. Therefore, you’ll need an external amplifier. In addition, the extreme bass requires more power to produce low-frequency sound.


A subwoofer with higher sensitivity will use less electrical power for moving the cone to produce sound. Thus, the woofers are thought to be more efficient in terms of power than the other models. Furthermore, as it uses less energy, it can last longer because the components are less hot and will last longer in time.

Ported or Sealed Enclosure

Ported subwoofers allow for the airflow to be accessible due to the openings inside the cabinet. On the other hand, subwoofers with sealed enclosures are closed cabinets that prevent the circulation of air. It is crucial to not overestimate the potential of an enclosure in terms of the overall sound quality. Subwoofers with ports can give you greater volume but don’t produce deep bass. If you’re after powerful bass with a stunning depth, sealed enclosures work best.

The Number of Voice Coils

The dual-voice coil subs is a specific option for those seeking flexibility in the wiring of their car’s audio systems. Although most subs have only one voice coil, DVC (dual voice coil) subs have two separate voice coils. Each has its own wiring, which is then placed in a single cone, after which it’s connected to a cone.

Frequency Range

Frequency usually refers to the variety of sounds your subwoofer will make and gives you an idea of the volume the subwoofer can play. It is generally recommended to look for a subwoofer at the lower portion of the frequency scale. It is much needed to keep in mind that enclosures will affect the frequency of the sound delivered to your ears so that the outcome will differ.

Frequently asked questions:

How do I install under seat subwoofer?

The majority of under seat subwoofers contain all of the critical components of a subsystem in one package. However, before installing your subwoofer, there are a few items you must do.

Find the appropriate spot to mount

It is essential to find the correct spot within your vehicle to install your sub. This is because the amp’s power will generate plenty of heat. Therefore you need to ensure that it has adequate ventilation. It is also recommended to place it in a place that isn’t difficult to reach.

Buy a wiring kit

Subwoofers powered by electricity don’t come with the necessary wiring, so make sure you purchase the proper wiring kit with all the wiring and fuses you require.

Disconnect your battery

To avoid shocks while installing, make sure to disconnect your batteries’ negative and positive terminals.

What size subwoofer fits best under the seat?

 Size is what you’ll be considering when it comes to your vehicle. Subwoofers for under seats are generally offered in sizes between 8-12 inches. The larger ones can be difficult to install under your seat. However, it depends on your vehicle, see how much space there is and then decide on the subwoofer.

Which seat do I put my subwoofer under?

You can mount a subwoofer either under the passenger seat or the driving seat. Placing the sub in the back seats, facing towards the back of the vehicle ensures that the bulk of the bass bounces off the hatch and moves to the front. This reduces the issue of phase and will improve bass response.

While the standard speakers mounted on factory-fitted cars will perform the task, the addition of subwoofers is nothing less than an added benefit.
