I have a 53 reg focus st170 and need to know which colour speaker wires are what LR+ &- etc can any one help the head unit is 6006E the 6 disc changer built in the head unit can anyone help?

 

The only help i can give you is that they are in pairs. Normally grey and grey w/ a black stripe. white and white with a black stripe. purple and purple with a black stripe, and finally green and green with a black stripe. As far as figuring which one is which, just do guess and check by hooking them up to the radio one at a time or you can take the covers off of the speakers and see which wires are attached to the speakers.

 

Maybe this will help?....... http://www.installdr.com/
