The wireless sub could be tricky. There is a receiver in there and an amp. You want to tap into the lines in between the receiver and the amp. This MAY not even be possible depending how it all is physically.
As far as the Klipsh. I don't really "get" what you mean with the crossover. From what I'm seeing....the sub takes an unfiltered signals through the DB9 connector. So basically just send it the left and right signals and you should be good to go. You can hook the satellites up or leave them unhooked.
Very helpful, thank you. I'll just leave the wireless sub alone for now. -- I think I was just using the wrong terminology. I was referring to what Klipsch calls the control pod (image attached), as a crossover. Audio comes into the control pod, which is attached to one of the satellite speakers, via a 3.5 audio cable. Then out to the sub through the DB9 cable. The Klipsch satellite speakers (which I'm not using) would then be connected to the sub. So now it looks like I have two options unless you see another.
1. Do I bypass the control pod and get some adapter for L/R audio to connect to my receiver, then the DB9 to the sub (or possibly even splice the existing cable if that's possible)? Would I lose my L/R channels and just get mono if I did this?
2. Or do I keep the control pod and get an adapter for the 3.5 male, which I'd connect to my receiver, and then out to the sub? If yes, should I connect my speakers to the outs on the sub, or keep them connected to the receiver?
