I have installed a Clark TST in my seating riser. I am wondering if I could run a front signal out of my main receiver ("B") into another receiver to use as an amp to power my TST.
Use a "Y" adaptor and plug it into the LFE output jack. Connect your subwoofer to one side, run RG6 coax with "F-to-RCA-Male" adaptors on each end to make a long cable to behind your seating riser. Run this into the CD input on the second receiver and run speaker wires to power the Clark TST's.
