Soundbar to subwoofer hookup


Hello, I was wondering how I could connect a 3.5mm out on a soundbar to a subwoofer?
Polk magnifi soundbar to Polk HTS-10, to be specific. Would a 3.5mm to RCA cable work? Should I go to the LFE or L/R on the subwoofer? My thinking is, without a receiver, let the subwoofer handle the crossover. Greatly appreciate your input, thank you in advance!

You need to find out the 3.5mm jack on the soundbar is a output or a input jack.

It’s an output jack. Currently it goes to the stock subwoofer which connects via 3.5mm
