There are two options.
1. Speaker wire isn't shielded but it does have two conductors like interconnect cable that would normally be used. If you can't solder something like these RCA plugs can be used http/www.aliexpress.com/item/10-pcs-free-shipping-RCA-Male-plug-RCA-Male-connector-RCA-plug-to-2pin-connector-RCA/1717166038.html?spm=2114.40010308.4.7.Xzan39
or you can cut a single RCA audio cable in half and splice them to the ends of the speaker wire.
You may pick up some RF interference because the speaker wire isn't shielded but it is worth a try. Set the receiver to small speakers and sub.
2. Connect the sub to the same terminals as the front left /right speakers. Set the receiver to large front, no sub. Not as good as option 1...
