I am only using 1 speaker for my reciever.In order for me to hear both left and right sides of my cd player,I must connect the left and right rca cable output of my cd player into the 2 female ends of the rca splitter,and then the 1 male end of the rca splitter is connected into the cd input of my reciever. Would using a splitter connected to a reciever with 1 speaker eventualy damage my reciever?

I used this splitter for a good 2 weeks on my brand new sony reciever and then when I disconnected the splitter and connected it again(while the volume was on high),my reciever blew a fuse and blew the transmitter. Is is possible that disconnecting and then connecting the splitter caused my reciever to blow?? Or it may be possible that as I was doing this,both female ends of the splitter touched.
