I suppose you could take the line level output for the sub off your first receiver, split it and connected one leg to your left channel in on your second receiver; then run speaker wire from the left channel speaker jacks to the second sub.  Over all I wouldn't recommend it.  Its pretty kludgy and unless its a high end receiver it may have issues trying to drive a sub.  You would probably be better much off looking for a second-hand mono amp.

Perhaps it would be helpful if we know if your sub is powered by its own amp or if it is a passive sub that is powered by your receiver's amp.


If you have a powered sub I don't see why you would want to put a second receiver into the loop as what would you expect to gain.

Most receivers don't have the power supply to deliver peaks required for the sub.  Also, it is usually difficult to find a dual 8 ohm sub which is the impedance that most receivers are most compatible with.
