Just got the car. Need some tunes. Don't have the connectors nor a reference of which wire is which. Was wondering if some one can tell me which one is which. Already got the battery, memory, and ground connected. Don't know which speaker wire is which or the attenna wire. Appreciate the help XD

 

what kind of car would help, but an easy way to find speakers is to take a drill battery and touch pairs of wires to it, one to positive and one to negative on the drill battery you will hear a pop from the speaker it is. also to tell which side is positive and which is negative when powering the speaker lines to the drill batter if the speaker pushes out it is in phase if it is sucking in it is out of phase. If you have bose or an amplifier this will not work*
