Tips for Choosing the Best 6.5 Subwoofer

As you can see from the above reviews, you’re certain that you can get a 6.5 car sub that will suit your needs. However, there’re certain factors you need to take into consideration when shopping. These factors will largely determine the overall performance of the subwoofer you’ll choose. Let’s discuss these factors in detail.

1. Power Rating

One of the most crucial factors to consider when choosing a subwoofer is its power rating. This is a factor you shouldn’t fail to check keenly. Typically, you’ll find two types of power ratings. These ratings are the RMS power rating and the maximum power rating. The RMS power rating is more important than the maximum power rating.

The RMS power rating represents the continuous amount of power that the subwoofer can handle. A higher RMS rating, in watts, means that the subwoofer can be able to handle more power continuously. On the other hand, the maximum power rating, also known as peak power, is the amount of short power bursts that a subwoofer can handle. Short power bursts are only temporary. Thus, give the RMS rating a higher priority.

2. Construction Materials

The kind of materials used to construct the subwoofer will largely determine its performance and durability. For instance, ensure the cone is made of a rigid but lightweight material to keep distortion low. Also, ensure the surround is made of a durable material.

The voice coil should comprise of a high-temperature material to withstand heavy usage without burning out. Also, ensure the magnet is strong enough to deliver a stronger magnetic field for more powerful lows.

3. Mounting Depth

You’re probably searching for a 6.5-inch car sub due to insufficient space in your car. For this reason, consider a speaker with a lower mounting depth. That way, you’ll find it easier to mount the subwoofer in tight locations.

4. Subwoofer Basket Venting

Another important feature to check is whether the subwoofer basket is sufficiently vented. Sufficient venting will allow for maximum air circulation throughout the subwoofer components. Proper air circulation is important to keep the subwoofer components cool, especially when playing music for several hours.

5. Ease of Installation

You’ll definitely appreciate a subwoofer that requires less effort to install. For instance, a subwoofer that can be mounted in a factory location will make the installation work entirely easier since you won’t have to cut out a new mounting hole. Also, the terminals for attaching speaker wire should be properly positioned for easier wire attachment.
