Advice on Bose Acoustimass 3 with Panasonic Pt170/175

I have some issues setting up my system with my existing acoustimass 3 Bose speakers and the Panasonice pt170 dvd/av amp.

It seems they they have individual outputs for the bass and surround sound unlike the common input to the bose speakers where the bass unit drives the speakers.

Can someone advise what i would need to do to make this setup work?.

Thanks
