Possible to use Surroundbar 3000 Sub alone or with Google home?

Would it be possible to use the Surroundbar 3000 subwoofer without the bar? The bar no longer works so before I throw the sub out is there anything it can link to? This was the only polkaudio product in our home so I dont have a option to try anything else. I have several Google home products. Is there a bypass to the TV maybe? Thanks in advance.
