Car Stereos: Jensen Car Speakers wiring install, jensen car, car speakers

Question
I have a Jensen tri. Speakers 150W I am not sure where the Pos. and neg. wires goes there are no marks one blade is narrow and the other is wide your help would be greatly appreciated. Thank You

Answer
Mike, the wide blade is usually the positive.  However, it may be different on those.  The best thing to do, is to try it both ways.  First, wire wide positive, and turn up the radio.  Watch the speaker movement.  Then, wire narrow positive, and turn up the radio.  Watch the movement again.  Whichever way it looked like the speaker was moving outward the most is correct.  Also, if you wire the pair the same, and compare sound to the fronts or rears.  They should all be heard well.  If you wire them up, and the other set (front or back) sounds quieter or louder, then they may be backwards.  Hope this helps, Scott
