How to Connect a Subwoofer: Low & High Level Connections

There are two ways to hook up a subwoofer to your stereo system: low-level and high-level connections. Low-level connections are made using RCA cables, which plug into the "sub-out" or "pre-out" jacks on your receiver or amplifier. High-level connections are made by running speaker wire from your amplifier's speaker output jacks directly to the terminals on your subwoofer. Keep reading to learn more about how to make each type of connection.

Decide where you want to place the subwoofer in your room

Deciding where to place your subwoofer in your room is an incredibly important step for creating the ideal home theater experience. Audio from a subwoofer will often sound muffled if it's placed too close to walls as the sound reverberates off of hard surfaces and can negatively impact its quality. The best place for a subwoofer is typically near the front of the room and away from any obstacles, often near the left or right of your media seat. Additionally, you should make sure that there's space around it for air to move so the audio can be heard with maximum clarity. With these considerations in mind, designing the perfect home theater space has never been easier.

Connect the subwoofer to the power outlet and turn it on

Installing and powering up a subwoofer to your audio system is an enjoyable moment. Adding a deep and powerful thump to your sound will bring that extra layer of depth and experience to the music. This can be done at home by making sure you connect the subwoofer to the power outlet, followed just by flicking the switch on. Once it is turned on, you can explore a whole new immersive way of enjoying your music or films. Make sure you check through all your connections and settings before enjoying this new boost in sound quality!

Find the appropriate cables to connect your subwoofer to your receiver or amplifier - low-level connections use RCA cables while high-level connections use speaker wire

Connecting your subwoofer to a receiver or amplifier can be a daunting task. Whether you are building a home theater system from scratch or just replacing some wiring, the proper cables are essential for getting great sound. When connecting at a low level, be sure to use RCA cables. The two audio signals travel through each channel respectively, left and right. For high-level connections, you should use a speaker wire. The speaker wire is designed specifically for the purpose of transferring audio signals and will provide optimal sound resolution and performance. Make sure whatever cable you choose is compatible with both the subwoofer and the amplifier or receiver so that you can get the best outcome possible.

Once everything is connected, turn on your receiver or amplifier and test out the sound system

Once you have all your audio components connected and set up, it's time to turn on the receiver or amplifier and test out your sound system! This is the moment of truth - did you do everything correctly? If all went well, you should be treated to crystal clear sound that will bring the music alive. Tune in to your favorite album or playlist and marvel at how much better your new setup sounds compared to before - it's like hearing a completely different recording! From this point on, any time you want to enjoy some music in style, just fire up the system and get ready for an immersive experience.

Adjust the settings as needed to get the perfect sound for your room

It can be difficult to figure out the sound settings for any given room to get good acoustics. Experimenting with different options can help you narrow down what works best for your environment, whether it's in a home studio or a theater space. Start by moving around furniture or adding acoustic treatments such as rugs and sound panels to try and dampen any natural reverb that might reflect sound waves. Then, try adjusting the EQ (equalizer), compression, delay, and other effects until you get the desired result. With enough adjustments, you'll be able to find that perfect balance of sounds in your room.


Installing a subwoofer in your home entertainment system can be a great addition for all of your audio performance needs. Having the additional bass in your room will give you an incredible sound experience. However, it is important to make sure that you take the necessary steps to make sure everything is connected correctly, and that you are taking proper safety measures. Not following the proper instructions or precautions can damage not just your audio system but potentially cause other hazards such as electric shocks and fires. By understanding the basics of installing a subwoofer, understanding the correct placement of it in your room, having appropriate cables handy, connecting all of the wires properly and turning on both your subwoofer and receiver or amplifier - you will certainly get closer to achieving that perfect audio setup in no time!
