How to Connect 2 Channel Receiver to Subwoofer

Firstly, a subwoofer, also known as a bass speaker, is designed to reproduce without distortion, those bass waves that traditional speakers do not reach, in order to reproduce tracks in multi-channel formats.

The audio tracks. 1 also known as LFE or Low Frequency Effects Channel, accommodate sounds below 4Hz, which are intended to shake viewers in the context of effects such as explosions, and create a realistic effect in terms of the nuances of the audios.

Active subwoofer connection

The receiver is usually equipped with a special RCA channel, designed to connect active subwoofers. Some models, basically these are already top-end devices from the budget segment, starting with the best 2 channel receiver under $500, provide multiple inputs, expanding the acoustic capabilities. The user only needs to prepare an RCA cable of optimal length and connect it to the corresponding connector.

It is advisable to give preference to a braided copper cable, which will retain the maximum signal volume. However, if you use an inexpensive powered home subwoofer, it won’t make much sense to increase the performance of the connected plug-in.

Passive subwoofer connection

The RCA cables will be used to connect the subwoofer to the amplifier. The output from the subwoofer can be mono or stereo. You can find them on the subwoofer main unit (rear side). In the case of the mono output, only one cable will be required for the output. For stereo output, you will need two cables. The colors of the two cables will be different to make sure you connect them to the right sockets.

The biggest advantage of a passive subwoofer is that it gives you the ability to work with different amplifiers according to your needs and required characteristics, which is not possible for active subwoofers. Make sure the amplifier is turned off before starting. Now connect the RCA cables already connected to the subwoofer input jacks to the amplifiers. The jack on the amplifier would be labeled LFE (Low Frequency Effects) or Subwoofer Out.

This is where the RCA cable is plugged in. Note that we are only discussing how to connect a single subwoofer, but multiple subwoofers can be connected to one amplifier.
