How to Choose the Best Car Subwoofer Underseat

Well, you have gone through some of the best under seat subwoofers, so, you have almost got the idea what kind of product you actually need. But before making the final choice, there are certain factors which you must consider so that you shouldn’t regret it after a few months of use. After all, you are investing your hard-earned money so you deserve to get the best value for your money.

Let’s have a look at these important factors:

Size of under seat subwoofer

This is the most vital factor when installing the subwoofer under the seat of your vehicle. Because the space under the seat is often narrow. Therefore, you should only go for the one that can fit in such a small space without any struggle. We recommend choosing 8” underseat subwoofer which fits well below the seat such that it does not protrude from the sides.

Type of vehicle

This is another factor which determines what kind of subwoofer you actually need. If you have Sedan that has more space for a subwoofer, then you can go for 10” models. However, 12” subwoofer may fit but will occupy a lot of space. And if you have a sports car that is usually smaller than other models then we would recommend you only go for the 8-inch subwoofer models. This way you can easily install your subwoofer under the seat without restricting the passenger’s space.

Right place for mounting

The most appropriate place for mounting an underseat subwoofer is under the driver’s seat or the passenger seat. If these places are occupied, you can use the rear area if you have a small car. And if you have a truck, use the area available behind the rear bench.

Frequency response

The range of frequency response determines how better your listening experience would be. You should go for the subwoofer that has the ability to reproduce all the low end frequencies; the ideal frequency response is 20 Hz to 200 Hz. However, the greater the frequency response would be, the clearer the original soundtrack would be.

Power & sensitivity

Just like design and other features, power rating also differs from one model to another. The power rating is the indication of how powerful the unit is. When buying an under seat subwoofer, pay attention to the RMS power as it is a more authentic representation of the power handling capacity of a subwoofer. For excellent sound output, make sure the power rating of the sub is equal to or more than the power the head-unit can supply.

A sub’s sensitivity is an indication of the amount of output it can produce. A sub with high sensitivity requires less power to put out the same amount of output as a sub with low sensitivity.

Ease of Use

When you have installed the subwoofer under the seat, you are sure to struggling with reaching out for buttons under the seat. Thus, it becomes a necessity to have a sub with remote control features. This will allow you to control different options from the comfort of your seat. If you want to use the onboard controls then make sure they are well positioned and easily reachable.

Having a small car doesn’t mean you will have to remain stick to low-quality sound. You have a lot of options as under seat subwoofer that can produce enough bass without compromising on quality and durability. Don’t look at their small size, they are quite powerful. And moreover, their availability in different size and shape make them the best fit for your car.

While reviewing these products, we tested around 30 products from the same category and listed only eight out of them which could prove their efficiency.

However, all of the listed products have some great qualities and features but the one which we found as the best under seat subwoofer in all terms is Rockford Fosgate Punch P300-12. We ranked this product at the top for some out of the box features. It has almost everything – compact size, powerful and accurate bass, and remote control to adjust the tone, sealed enclosure, intelligent turn on or off function, flexible power connector, and excellent sound balancing with its in-built equalizer. When coming to the downside of this product, it only lacks the stiffness and thickness in its plywood panel and high price tag is also one of the factors that may disappoint you.
