power probe & multi meter, worked out which wires to splice together from the amp so it is completely out of the equation & the speakers are running from the head unit! Dave if you or anybody else wants to know which colours go together just give me a shout! Why on earth they couldn't just use the same colour wires into & then out of the amp is beyond me & why on earth aren't the speaker wires the same colour behind the dash & the doors or the amp???
I like a challenge but that had me stumped for a while this aft, but at least I have tunes again now!
