Hi @cjcowden.

Thanks for reaching out and welcome to the community! We’d be glad to help.

Amp has an auto-detecting RCA subwoofer output with a user-adjustable 50-110 Hz crossover. Simply connect your subwoofer to the Amp’s RCA output labeled SUB. 

NOTE: The subwoofer output is disabled when Amp is being used to power surround speakers for a Sonos home theater product.

You may also refer to this article that will guide you through setting up your Sonos Amp. 

Let me know how that goes.

Hello, the article didn’t address my issue. My sub is actually a pair, so I have 2 that need to be connected. So do I connect both to one amp or one to each of my 2 amps? I already have 2 pair of speakers connected to both amps. I am not too knowledgeable on audio equipment. I don’t want to overload the amps, or connect incorrectly.
