I just bought a js-1000 subwoofer. I have a Pioneer VSX-D507S Receiver and need help in how to set this sub up. I tried putting a cord directly from the receiver subwoofer pre-out to the Line In on the sub but that didn't do anything. Do I need to run my front speakers through the sub? The sub has a switch that says phase 180 or 0, what do I set for that? What should I set the Low Pass Frequency at? Anything else I should know? Thank-you!
