Hi, I want to connect my recently purchased mp3 jukebox to the head unit of my car stereo. My head unit has 1 pair of RCA sockets which are currently being used by my CD-changer. I want to use one of these to connect the mp3 player to the stereo: But obviously there's no room for it cos of the changer, so would I be able to use 2 of these: to sort of split both pairs of connectors into the 2 sockets at the back of my head unit? Would there be any problems with either of the two stopping the use of the other? Thanks. P.S. I don't want to use a tape adaptor for aesthetic purposes, and have already got a soundfeeder.
