Things to Consider When Buying an Under Seat Subwoofer
Finding the perfect under seat subwoofer for your car won’t be a daunting task if you know what you should be looking out for. In this buying guide, we’ve listed out what makes a subwoofer an ideal choice to help you make an informed decision while paying attention to your needs and tastes. Before you go shopping for an under-seat subwoofer, these are the important factors you should consider:
When it comes to subwoofers, size is an important factor. A subwoofer’s size determines how it behaves. A small subwoofer will be more responsive and faster. For example, a subwoofer with an 8-inch size will work perfectly for fast music and will produce an excellent bass response and clarity but won’t add loud and heavy bass to your music. The good thing is that they’re easy to install and will fit nicely under your car seats whether you drive a small car or not.
A 10-inch subwoofer can also keep up with fast-paced music and works well with heavy bass producing nice music clarity and good bass response. They even produce more bass than the 8-inch subs and aren’t difficult to install as well. The drawback of this subwoofer is that if you want to increase its volume, you’ll need to double the subwoofer up for bigger bass.
Then we have the 12-inch subwoofers that are perfect for heavy bass and produce a more decent bass response and clarity than the 8-inch and 10-inch subwoofers. The only drawback is that they’re harder to install and could intrude on the passenger seat’s space.
Indeed, subwoofers will add plenty of bass to your car audio system and they could be quite loud, but don’t expect your neighbors’ windows to vibrate when you pass by. There are two values for you to keep an eye on, they’re measured in watts and are simple representations of how much output you can get from your subwoofer.
Peak power is the maximum wattage a subwoofer can handle in short bursts. If an amp produces more watts than your subwoofer can handle, it could lead to sound distortions or even damage your subwoofer. The peak power, like we earlier mentioned, is how much power your subwoofer can handle in short bursts but it has little or nothing to add to its audio quality. So, what you should be focusing on is the RMS power of your subwoofer.
The RMS power rating is the real power an amp put out steadily. A subwoofer’s RMS rating helps measure how much power can be channeled through your subwoofer without causing distortions or harming your subwoofer. You’ll need to take the RMS power of your subwoofer into account when you decide to pair up an amp with it. If the power produced by the amp is more than the subwoofer can handle then you should turn it down most especially if you can hear distortions. The closer the amp and subwoofer values are the better for you and your subwoofer.
With that said, make sure that you go for an amp that can produce a 75% minimum of the subwoofer’s watts but won’t exceed 150%.
Note: With good speakers, a cheap amplifier can sound great and the best amplifier can sound awful when paired with poor speakers.
A subwoofer’s sensitivity is measured in dB and it relates to how loud your subwoofer will play your music at certain wattage. This means you should go for a subwoofer with higher sensitivity to go with a higher power [wattage] value as power consumption and sensitivity go together when it comes to subwoofers.
For example, if you have a 90dB sensitive subwoofer, it will need 100 watts. Our advice? Go for a subwoofer with a sensitivity that’s greater than 92 dB and if you go for one that’s below than 84dB then you shouldn’t expect superb sound quality.
Your subwoofer’s frequency response range helps you know how your music depth will be like. A larger frequency response range will deliver better detail, crisp highs, and deeper lows. We advise that you go for a subwoofer with a larger frequency response range for you to get the best clarity and most detail from your music.
Your subwoofer’s weight is another vital factor to consider when you’re searching for the ideal under-seat subwoofers. It’s not ideal to put huge and heavy subwoofers under your car seat as there would be an uneven weight distribution. So, it helps if you to always keep the kind of car you drive in mind so you’d easily know if the weight of the subwoofer you’re considering will work for it or not. You should also go for a subwoofer that will fit nicely between your seat and your car’s floorboard.
Your subwoofer’s impedance is directly linked to the quality of sound you should expect from it as well. It also has a lot to do with the subwoofer’s electrical load and resistance. So, if you’re looking for better sound and deeper bass, you should go for a smaller Impedance value like 2-Ohm. At this value, your subwoofer won’t need to fight against so mu h resistance and so you’ll be getting the best possible sound quality.
If the subwoofer you’re considering comes with a dual voice coil then it’s also a great choice as the coils will work to fight the same impedance level. The result? Increased output and better sound quality. A 4-Ohm subwoofer could also work but you won’t be getting as much sound quality and same output as you’d get from a 2-Ohm subwoofer.
FAQs: Frequently Asked Questions
Q-1: What Is the Function of a Subwoofer?
A subwoofer (sub for short) is a dedicated low-frequency component that can cover deep and low-frequency ranges that car speakers can reach. They come in different sizes, designs, and layouts. They have been designed precisely to reproduce even the deepest notes in the musical spectrum. Indeed, most car speakers can’t play deep notes and could sometimes seem like your tweeters are bright and so, you’ll need a subwoofer to back them up. By using subwoofers for your bass reproduction, your other sound system parts will be able to focus on the frequencies they’d handle best.
Q-2: Would I Still Hear the Bass Even If My Subwoofer Are in the Trunk?
Yes. As long as your car’s trunk isn’t soundproof and sealed, you’ll still be able to hear the bass from your subwoofers without experiencing any difficulty. Generally, the bass will travel through the materials that separate the passenger seats and the trunk. If you feel the bass reaching the front seats aren’t as full as you’d want it or as full as when you’re close to the subwoofer, then you can fix the problem by making a couple of small holes in the rear deck and then covering it up with sound transparent material.
Q-3: What Is the Difference Between A Woofer and A Sub-Woofer?
Simply put, a woofer is a part of the subwoofer. Generally, a subwoofer consists of one or more woofers mounted in an enclosure or box. This box acts as a resonance chamber allowing for more airflow to get to the rear of the speaker cone resulting in a significant increase of sound pressure level [SPL] and a richer and fuller bass.
Q-4: What Are the Factors that Affect Subwoofer’s Performance?
These are the factors that can affect your car subwoofers performance:
- Frequency response
- Cone build material
- The type of enclosure
So, if you’re looking for a car subwoofer that can hit deep lows, then you should consider a subwoofer that’s designed for use – with the lowest possible frequency range – in a sealed box. Always remember that the larger your subwoofer, the better the bass reproduced. You can use it as a rule of thumb and you’ll see that you’d be making the best under seat subwoofer choice.
Q-5: What Kind of Bass Response Can I Get from An Under-Seat Subwoofer?
Well, it depends. Some subwoofer units will softly tickle your stomach with their hard bass while other subwoofer units hit you hard with their bass notes. If you’re looking for those hard hits from your bass then you should for a subwoofer with a higher sensitivity value and a frequency response that gets as close as possible to 20 Hz – 250 HZ plus some decent power level. In the end, how much bass you can get will depend on how much your stomach and ears can handle.
We’ve listed out the10 best under seat subwoofers for you to try out in this article. They’re all high-quality subwoofers that will bring you dependable performance and comfort. Their installation process is simple, straightforward, and quick. What else? They also bring you great sound quality that will greatly improve your car sound system.
If you’ve got a small car and would like a decent bass production then the under-seat subwoofers in this article are worth considering. Don’t be deceived by their small sizes as their performance is quite superb.
However, you should know that your ideal under-seat subwoofer won’t need to have the biggest cone or be the most expensive on this list. You should go for the one that works best for your needs, budget, and tastes.
