I'm having some sort of disconnect between radio & speakers.

My Onyx SiriusXM radio is disconnecting from my speaker system while it's on. Nothing is coming in contact with the the radio or the speaker. But every so often the radio completely resets, and all we hear is a consistent popping.

A few things to note:

• The speakers remain on during this time.
• This does not happen with the Onyx radio is plugged into other cradles.
• We bought this used on Amazon, had no issues with it for a few months, then randomly it began to happen.
• No damage that I know of, has happened to it since buying it (sits on table)
• We only use it while plugged into the wall, not on battery.

All I can come up with is there is some power failure between the connection of the speaker's cradle and the radio.

Any thoughts?

I've included some stock photos of what the SiriusXM SXSD2 looks like below.
