If you’re looking to add some extra bass to your music, you might be wondering if you can connect an active subwoofer to an amplifier. The short answer is yes, you can! However, there are a few things you’ll need to take into account in order to get the best sound quality possible.

Active subwoofers are powered subwoofers, meaning they do not need to be connected to an external amplifier to work. The power source is frequently an integrated amplifier. There is no requirement to connect it to an external amplifier, thus. 

Attach a power supply to the subwoofer, and you are ready to go. Typically, an active subwoofer doesn’t require an amplifier to produce more sound. To transmit data, you would however wish to link it to an amplifier.

In this article, we will provide you with a detailed guide on connecting an active subwoofer to an amplifier.

Why would someone want to connect an active subwoofer to an amplifier?

Increased Power Handling

By connecting your subwoofer to an amplifier, you will be able to increase the amount of power that your subwoofer can handle. This means that your subwoofer will be able to play at higher volumes without being damaged.

Improved Sound Quality

Adding an amplifier to an active subwoofer also improves sound quality. When you join an active subwoofer with an amplifier, the sound quality is increased because the amplifier is able to provide a cleaner power source to the subwoofer. It will be able to produce a clear and more accurate sound.

Flexibility

An active subwoofer with an amplifier is also more flexible than a passive subwoofer. This is because an active subwoofer with an amplifier can be placed in any location in your room, whereas a passive subwoofer must be placed near an outlet. This means that you can place your active subwoofer in a location that provides the best sound quality for your room.

Data transmission

The amplifier is primarily used as a data transmission source or as a conduit for information to travel between your passive speakers and the rest of your sound system setup.

Connect an active subwoofer to an amplifier using RCA cables

Look at the subwoofer’s line-in and line-out. Get an RCA cable and connect the devices if they both use RCA. If the cable has split ends, you will locate the right and left ports where the split ends should be inserted. Therefore, insert the ends into the appropriate ports. Additionally, look for the right and left RCA connections designed for the subwoofer output on the amplifier. If you discover the plugs, connect them as necessary.

Pros of this Method

  • The method is straightforward, and if you have the appropriate cables, it should take you a few minutes to set up.
  • This is an inexpensive way to connect your subwoofer to your amplifier.
  • It is a reliable connection method, and you will not have to worry about losing any sound quality.

Cons of this Method

  • You may experience some sound quality loss due to the fact that RCA cables are not designed for high-fidelity sound.
  • If you are using a long RCA cable, you may experience some signal degradation.

Factors to Consider While Making the Connection

Location

The subwoofer’s placement in a house or room will either improve or degrade the sound. It will sound better and make a difference if you place it in a room corner. Keep a tiny subwoofer at least four feet away from the main speakers if you have one. A huge subwoofer is an exception; just make sure you do not place it in an enclosed room.

Maintain a third-of-a-space between the subwoofer and the surrounding walls. It will produce distorted noises and bothersome vibrations if you keep it too close to walls. On the other hand, placing it in the exact centre of the space makes the sound it creates less audible.

Place your furniture so that you can make the most of it after the subwoofer has been placed properly. To experience the subwoofer’s output, you can move to various parts of the room and listen as it operates. Move the sub as near to the ideal location as you can without disconnecting anything when you’ve found it.

Configuration

Make sure the specs and crossover controls are adjusted to the maximum frequency by checking the subwoofer setup. The sound output can be limited by poor configuration, giving the impression that the subwoofer is underperforming.

Levels

Playing with the levels to achieve a perfect sound is vital. If you want to get more bass, you will need to raise the volume. But, beware of making the mistake of thinking that more bass means better sound.

An overblown bass will only damage the quality of the sound. Therefore, adjust the volume until you get a clean and subtle bass that does not interfere with the clarity of the music.
