I am running a 4 channel amp to the front speakers in my 03 Z. I don't want to force another set of wires through the door, so i would like to just connect it inside the cab to avoid it. My question is what color is the speaker wire inside the cab. I know they are blue and red in the door but when i try using those inside the cab they aren't the same. Tried searching on here but keep finding mixed answers.
