How to Add an External Amplifier to Your AV Receiver
Why Add an External Amplifier?
Scenario 1: Play additional channels
Scenario 2: Increasing Power for Front Channels
Even if your AV receiver can run all the channels you need, the power output may not be enough, especially for large, high-performance speakers. In this case, you can use a powerful external subwoofer to run the left, middle, and right front channels, which are most important for the home theater experience
Connecting an External Amplifier
Connecting an external subwoofer to an AV receiver is a relatively straightforward process. Here's what you need:
RCA cables to connect connections from input connections to external speakers to AV receivers.
The external speaker itself can be a dedicated power amplifier or built-in amplifier that includes both pre-subwoofer and power subwoofer parts.
The general steps are as follows:
1. Find presets on the back of your AV receiver. They are usually classified as Front L, Front R, Center, etc depending on how many channels the recipient can follow.
2. Connect connections to relevant input connections on an external speaker using RCA cables.
3. Connect the speaker wires to the output connection on the external speaker.
It is important to note that the specific location and marking of pre-emission communications may vary between different manufacturers of AV receivers. To help you determine the right connection, we've included examples of several popular brands

Conclusion
Adding an external subwoofer to an AV receiver can be a great way to improve the power and performance of your home theater system, whether you need to play additional channels or provide more power to the front speaker. By understanding different scenarios and the process of connecting external speakers, you can take your home theater experience to the next level.
