help findding the speaker wires that runs from receiver to door opening

My car has a Sony Xplod cd receiver (it was in the car when I bought it) and my door speakers keep fuzzing out every time I turn the volume up. I just bought a new set of speakers and its still happening. Now im at running new wiring to the door. I pulled the receiver out and it looks like the guy did a lot of splicing. Is there some trick I can use to find the wires easily? Its really annoying me. Oh yeah when I managed to get the receiver back into the dash (it took me about 20 min.) my remote for my amp got jarred loose somewhere, so now I have almost no audio. Help! Model is 92 Civic CX H/back.

search for wiring honda headunit on here or on google. that should get you the wiring diagram and the color of each wire you need to find.

thats what I did. It still took me all freakin day just to run two measly wires
