I am changing out the speakers in my car, how can I tell which wire is positive, and which is negative??

Question

I have a 95 honda civic, I know generally the blue, or red wires in these cars are positive, but I believe the stock wiring was changed out before I bought the car used. Someone please help!!

Thanks in advance

Usually the wire that has the bigger connector at the end of it is the positive wire

Answer 2

Look for a black stripe, that is the ground side for the speaker.
