  • Connecting using an LFE subwoofer output. 
  • Connecting using a speaker level output, also called the stereo RCA.

If you are familiar with a subwoofer, you might know that the subwoofer requires two inputs to provide the desired output. It needs power, obviously, to power the subwoofer system and a signal to get connected. For power, you need to connect your subwoofer to a current source.

However, you need to ensure that the subwoofer is safe, so it is advised to connect it to a power protection device and then connect the power protection device to the current source. Thus offering complete efficiency to the power input.

Although the earlier mentioned way of connecting the subwoofer is predominantly used, some of the subwoofers and speakers do not come with an LFE port. Thus we can connect a subwoofer using stereo RCA ports.


You will see a left and right stereo RCA connector on your standard speaker. All you need to do is to plug in the RCA cable to either the right or the left side of the port on the speaker. However, if you have a split end at the cable, then you need to plug them into both the right and left RCA port each. 

Then you have to hook the other end of the cables into the speaker output of the receiver. If you observe, you can find that this is the same as connecting a basic stereo speaker. And now you can enjoy the bass output of your subwoofer at its best.

But sometimes instead of the cable, you might have spring clips. You can hook them all up using a speaker wire and thus making the subwoofer connected to a receiver just like a basic stereo speaker.


So that's how you make your connections to the subwoofer using speaker outputs to optimize the bass on your subwoofer. Now that you know the trick to connect your subwoofer this way, enjoy the best out of it!!
