I want to take an extra 5.1 set of speakers and plug them up externally, preferably to my iphone. It uses the standard Green Black Orange 3 cord set up. I read this tutorial on how to convert it to one with adapters, but I'm not sure of which to use. The tutorial says
Purchase two adapters: one to combine your 5.1 signal into left and right RCA signals, and one to convert your left and right RCA signals into a single stereo TRS signal.
Step
Plug your orange, green and black cables into the TRS-to-RCA adapter.
Step
Plug the second adapter into the first, converting the two RCA signals into a single TRS stereo signal. This second adapter can now be plugged into the single audio output of your computer or small electronic device.
Can someone link me to these two cables on Amazon? Thanks for reading ^.^
