Im havin trouble tryin to find the original wiring, i have no rear speakers but people say the wiring is still there. can any1 help please.
Also, if i was to run the new speaker wire, which terminals would i wire it 2 on my headunit???
thanks for help!!!

Green/Brown and green on one side and White/Brown and White on the other, usually taped rite up in the grey plastic close to where the speaker would have been on either side. Pretty sticky to get to and a pain in the arse to find, but saves a lot of time.

Hope that helps bud.
