Polkaudio sub to Denon amp

I'm an amateur and don't know much about home entertainment systems
I have a Denon AVR 888 and just bought a polkaudio sub, PSW10.
I wasn't expecting the 2 L/R jacks on the sub, so I'm looking for that cable.
I've read some posts here abiut filter setting. So I'm wondering if I will just be able to plug and play, or will I need to play with settings?
Thanks!
