I have an old Carver "Z Band Coupler" that can do this via the speaker terminals of the receiver.
I used it back in the early 1990's to connect one of the original made in usa Adcom 535 amps to a HK Receiver.
Funny but I still have this Carver piece and it is in mint condtion as I never wanted to give it up.
