ok but lets say you have no reference at all, and you have no way in telling what wire on the deck is what...
besides the above mentioned is there any other way? Im just trying to think from an electronics engineering standpoint...
Like im trying to see if theres a method or tool out there to see the output and see if the sine wave is in reverse polairty or forward coming from the leads...etc...
I have everything wired fine im just thinking from a wondering point of view.

jeeez
I know how to trace them, Im already done everything, im not a n00b to car audio, I am trying to stir up some info on if there was a way to do it through electronics perspective using equipment.
Everyone is posting the same damn thing... what Im trying to get across is the fact that if there was no information available at all, yet you had tons of electronic equipment lying around at your desposal like an oscilliscope, multimeter, etc is there a way of using tools like that to diagnose?
Or would you have to pull apart the deck and trace the leads back to the PCB board and figure out which trace leads to the positive and which to the negative etc... purely from an electronics standpoint.. since I am taking that in college so I always have a nack to want to know how to go about finding it the hard way..

so you don't wanna trace the wires in the car but rather figure out the wire output of the deck
it's been a long time but I think an oscilliscope would do the trick once you figure out wich pair of wires go together you could feed both inputs in and make sure they are in phase
IMO actual + & - don't really matter all that much as long as both are the same (in phase)

hmm kew thanks Dukk
as far as oscilliscope I tried it yesterday but each time i swtiched the leads the sine wave was still the same, so that theory was a no go for me.. Everything is working fine now, I just brought up this discussion for simply discussion only, as I was wondering how it could be done.
