Tip & How-To about Car Audio & Video
Say your doing a car install and the speaker wires arent marked with a positive or negative symbol and you cant get to the back of the speakers or/and it would take a lot of extra time to take the doors apart so you can get to the back of the speakers,all you simply have to do is take the two wires coming from the speaker,grab any AA battery and put one wire on the positive side and the other wire on the negative and as your doing this observe the speaker and see if the speaker is sucking in or out.If it flexes out,then that is right and whatever wire is on the positive of the battery is your positive of the speaker and naturally the other one is negative.If the speaker flexes in then that is wrong ,just switch the wires and that will let you know which is which-Have Fun and Always unhook your battery when doing install-Thanks Steve
