Read the entire description. I found this one quite funny "I REALIZED THAT THE AMP LACKED THE RCA INPUTS NECESSARY TO USE MY RECEIVER FOR THE AUDIO SOURCE. INSTEAD IT HAD SOME STRANGE THREE WIRE TERMINAL THAT I'VE NEVER SEEN. TO THIS DAY IVE NEVER HEARD OF A 3 WIRE AUDIO SIGNAL WIRE. VERY DISAPPOINTED"
