I can't get my stereo to work. Which wires are the power, ground, etc. All the diagrams I find are different wire colors. There is only 7 wires and four speakers. Still can't figure it out any help would be good.

 

see if this is any help, if not your going to have to test them with a speaker tester and a multi meter
