Looking to team the two transmitters that came with my two pairs of RS-180 headphones. I want to connect them in tandem (with standard audio cables) to my amplifier and locate them at opposite ends of my house to extend my wander-room. Any ideas?

First time i hear something like this...all my phones are wired. 
 
Try to look at the DIY forums.

Just as an idea, my single pair reach easily about 65 feet in or out of the house.
