Hello PK

I don't think so. Those are probably line outs for older receivers or amps which don't have a preout for the sub. You can connect the speaker outputs from your amp or receiver to the subwoofer instead of the speakers. The sub has a xover which will direct lower frequencies to the sub's amp and direct the rest of the output to the speaker terminals you're looking at. You then connect speaker cables from those output jacks in the sub to the speakers and voila.
