How to Choose Best Subwoofer for Car

One of the most challenging things when tuning up your car comes about when you want to go ahead and give you music system an upgrade. Since there’s nothing as frustrating as hitting the road and having to put up with a poor sound quality, everyone wants the best, right?

Having the best bass is one of the major areas of concern when tuning up your sound system and this goes hand in hand with having the best subwoofer installed. getting the best however, is not that simple, there’s quite a lot to take into account which is where we come in.

Below is everything you need to pay attention to if you really do want to have the best subwoofer for your car.

Choosing the right size

Being the main factors that dictates how loud and deep your bass is going to be, it’s important that we pay close attention to it.

For the size, the rule of thumb is normally the bigger the subwoofer is, the better the bass quality you’ll be getting and vice versa obviously. Before you go for a huge subwoofer, you should consider whether or not you’ve got enough space in your car to have it installed. In addition to this, you should take into consideration whether or not you’ll be needing an enclosure.

Speaking of the enclosures, you could go ahead and get a smaller subwoofer but have an outstanding enclosure for it. This way, you’ll get to spend less on the sub. If neither cost nor price is a problem, you could go ahead and get the largest subwoofer you can get your hands on for a loud and low bass.

As important as it is, the size is just but a tip of the iceberg when selecting the best car subwoofer. There’s plenty more to complement this. Which we’ll take a look at shortly.

How much power is really enough?

Just as important as the size of a subwoofer is, a large subwoofer can be somewhat useless if it does not have he amount of power that it takes to produce an outstanding bass.

For the power, you’ll normally have to deal with both the RMS and the peak power. Sine you don’t want to blow your subwoofer, you ought to pay attention to the RMS power since this is what the speakers can run on constantly without any sound distortions, lags or even worse, damaging your voice coil.

The higher the power is the better the bass quality you’ll be getting as far as the RMS is concerned. Thought the sub can momentarily play with a power level past the RMS, supplying more than enough power will definitely cost you either the whole subwoofer or you having to put up with sound distortions.

The impedance rating

Yet another important thing to pay attention to is the impedance. Most of the subwoofers you’ll get will normally have a 4-ohm impedance. Though this is tolerable, you could get a better bass from a 2-ohm impedance.

It is not always about the ohm rating on the speakers. Some may come with dual voice coils which make it possible for you to wire them up differently as compared to those with a single voice coil.

As compared with a sub that’s got a higher impedance, one with a lower impedance will be able to channel more power which means that you’ll utilize as much of the RMS as possible. This in turn leads to the production of a louder and lower bass.

Is the sensitivity really good enough?

Whereas the impedance determines the amount of power the sub is going to utilize, the sensitivity goes hand in hand with the power.

The rule of thumb here is that the higher the sensitivity is, the less power you’ll require in order for you to produce a sound quality that matches up to that of a sub with a lower sensitivity.

The best rated subwoofers will normally come with a sensitivity rating that’s above 88dB. If you get one that’s got a sensitivity that’s as high as 92dB, it’s even better and if it gets to as much as 102dB, then this is probably the best.

Also, with a high sensitivity rating, the bass will be clearer at a high volume as compared to

It’s definitely amazing to go for a subwoofer with a high sensitivity but at the same time, you’ll have to spend a little bit more on the same

The frequency response

We’ve talked about getting a loud and low bass. Well, let’s have a look at what having a low bass is all about, shall we.

Whereas the treble is delivered at high frequencies, the bass, on the other hand is delivered at the low frequencies. When taking a look at the frequency response of your subwoofer, you should always pay attention to the lower end of the scale.

Since the lowest possible frequency that the human ear can understand is 20Hz, the best subwoofer ought to have the lowest frequency that’s around this, say about 30Hz.

Provided all the other aspects mentioned above are at their best, you’ll definitely end up with both the loudest and the lowest bass.

Quality construction

You don’t want a subwoofer that will disappoint you after a while now, do you. well, you ought to take into consideration what makes up your speaker.

Subwoofer construction

Starting with the surround, this should be durable and flexible, probably made from a material such as rubber. The cone ought to be lightweight and rigid in which case it should me made from a material such as polypropylene.

The voice coil on the other hand should be tolerable to high temperatures in the sense that no matter how much power you supply to it, it won’t threaten to blow whatsoever.


There’s a lot to consider when getting the best but considering that you’ve got the best buying guide at your disposal, it shouldn’t be trouble at all to get the best. The secret to it all is only going a subwoofer that’s going to meet your exact needs- someone else’s best doesn’t have to be your best.

We’ve also got a variety of subwoofers of different sizes and prices from which you can choose one that will give you a kick for your buck.

Above all else, pay utmost attention to the above aspects and be keen while choosing one- you deserve the best.
