Buying Guide: What to look for when buying the Best Car Competition Subwoofer 

If you are shopping for the best competition subwoofer for your car, there are a few things that you need to keep in mind. Here are a few tips to help you find the right unit for your car;

1. Competition vs. Standard Level Subwoofers

Considering that car subwoofers come in different sizes and designs, it can be an overwhelming task to choose the right one for your car and, further, to differentiate between a competition level and a standard subwoofer. While they are more or less the same, competition subwoofers are designed for high output, enabling them to produce more impactful bass. They are also much bigger and more pricey when compared to regular subwoofers.

2. Bass

Bass is probably the most important consideration and you may want to focus on a subwoofer with a great low-end. An excellent great end is what enables you to not only hear the subwoofer but also to feel it. A powerful bass translates into a stronger low-end and this will have more impact on those around you. You should, however, make sure that you match your speakers and amplifiers correctly so that the sound does not become muffled.

3. Power Ratings

As stated earlier, a competition sub has to be powerful. That’s why you need one anyway. You need to check the RMS value, frequency range, and SPL. Here are the key indicators;

  • RMS Power- This is the measure of the amount of power a sub can handle continuously. This is the most important rating as it is the one that determines how powerful the unit is. As such, the higher the rating, the more powerful the unit, but you should ensure that you have an appropriate amplifier to get optimal performance.
  • Peak Power- While many people consider peak power as the maximum power capacity, it is quite different from how a subwoofer works. Peak power is the maximum voltage that a sub can handle during short bursts and it affects its performance to a certain extent.

4. Speaker Compatibility and Configuration

The size of the sub is an important factor as it will determine the highest and the lowest tone. A bigger subwoofer will provide a better bass, but you should consider the space available in your car. However, you should have it in mind that big subs are more difficult to transport and install than small ones. The most common sizes are 12-inch and 15-inch subwoofers, and choosing one size over the other will be determined by personal taste and the available space.

5. Type of Enclosure

You will also need to consider the type of enclosure, as just like the size of the subwoofer, it also has an impact on the overall sound. By enclosure, we are referring to the box that holds the sub. A sealed enclosure will ensure that you get deep bass, while an open one will deliver that accurate and tight bass. A ported enclosure, on the other hand, will provide a louder bass making it perfect for audiophiles who prefer loudness over accuracy.

The Final Word

Competition subwoofers provide a sound experience that is not so common in our everyday life. We spend a considerable amount of time in our cars, and it is definitely a perfect time to soak ourselves in our favorite tunes.

Competition subs can be used by anyone, but they will be exceptionally helpful if your listening needs go beyond average bass. They are the kind that will vibrate your eyeballs and bones. If this is what looking for, then any of these giants provided above will nail it.

These subwoofers are not as cheap, so you may want to select one suits your needs perfectly. Luckily, our review provides you with several options and whatever choice you make, always ensure that your competition subwoofer gives you a true bass presence.
