just spent all day trying to wire up my rear speakers to my aftermarket head unit . but could not work out where the existing cable goes in order to hook it up directly to the stereo !?
Can I even just extend the existing cable to connect to the stereo rear speaker outs on the hu?
I checked in by the sub in boot but theres so many cable there and none seem to match up to what is coming out of the actual speaker in terms of wire colour?
please help really need to get the speakers working?..
thanks in advance

Now fixed.
New cable from HU wired into the sub harness to bypass sub and power speakers from HU amp
