subwoofer help Convert wireless Polk audio subwoofer to wired

[Kameka]

Hi friends, I found myself with an extra Polk audio wireless subwoofer for my Polk audio 6500BT sound bar. I’d love to be able to use it as part of a wired stereo system in the future. I’ve attached all the pictures of the board I pulled out of the enclosure in the hopes that someone will easily be able to tell me where the Bluetooth adapter is and where I can solder on an RCA connector to have audio provided by a wired device. My dad has worked on a built electronics for years, just not audio ones. So I’m confident in his ability to remove the component (if necessary) and solder in the new connectors, I just need to tell him what needs to go, and where to make the new connection. Would love some help and direction. In the pictures I’ve included the barcode of the sub with model number info. 

Let me know if I’ve missed providing any key information. Happy to do what I can to help you help me

 

Thanks in advance

Almost all of that is amp.  I can’t pick out the wireless bit.  I looked for antennas but I don’t see any, which doesn’t mean anything because there might not be any.  If it was Bluetooth one might be able to connect it to a wireless system wirelessly, but just “wireless” could be anything.

Thanks Bombastinator for taking a look. I’m pretty sure it is wireless through Bluetooth as during setup there is a bit of a pairing process. 
 

I was also getting some wireless interference between the sound bar and the sub from what I believe was my home wifi router being too close to the sound bar which would be sending the sound to the wireless sub. I believe the router was 2.4 GHz. Not sure if that tells anyone anything.

Bluetooth is really expensive compared to other stuff.  If it’s actual Bluetooth it will have the logo emblazoned everywhere.

I have the 6000 series polk wireless subwoofer. Have you found any information on how to make this wired?

The subwoofer needs to be paired to a soundbar before it can enable the amplifier. If it can't find a soundbar to pair with when you turn the switch on (flashing green), It will go on standby mode (steady red light) after a few minutes. It pairs with the soundbar using ElevenEngineering proprietary digital wireless modules (both soundbar and subwoofer).
