Look on the back of your receiver and there should be pre out jacks. Run the 2 main out puts via rca cables into an unused input(other than phono)in your Pass pre amp. Switch your pre to that source every time you use your ht system. You just need to have the volume, on the Pass set at the same position every time you set your levels and watch movies/tv. You don't need to mess with the amps or speaker wires. If you need additional help, send me an e-mail and we can connect over the phone. Happy to help.
