Good Day All,
I just bought a Pioneer VSX-517K and it includes a sub woofer pre-out. My system before that was a cheap starter system and I upgraded to this. So I will be using my speakers from my old system. But the sub woofer from the old system contains +/- (red and black) connection cables. So I was wondering if I could connect my old sub woofer with my new Pioneer receiver. Again, my receiver only has sub pre-out and my sub only has +/- connections.
