Hello, as I was reading through this I think I understand but want to make sure I am correct. From my understanding, Can the "Line Out" on the Home Receiver be used in the same way as the "Line Out" in a aftermarket radio for a vehicle? Meaning for a vehicle subwoofer you connect the subwoofer to a amp and the amp to the Line out of the aftermarket vehicle radio. For the home receiver that has a single rca connector for a subwoofer meant to be connected to a self powered home theater subwoofers. If the home theater Receiver has a line out, could you connect that to the same amp and subwoofer set up you would use in a vehicle?
