I can’t seem to find an answer to this question anywhere...
I am in the process of fitting aftermarket Pioneer speakers to the front and rear doors, however I can’t seem to find a diagram/answered question anywhere which says which of the wires connecting to the door speakers are positive or negative. My wiring has L3 and M3 printed on black wires and that is all. No indication on the terminals, no other symbols on the wires etc. I haven’t wired speakers into a car before and don’t want to do it wrong, although I know I can’t damage the speakers if they were the wrong way round, I would like it to all work as it should.. Anyone had any experience with this to date? Cheers all, Matt

As long as you connect the L3 and M3 wires to the SAME contacts on the new speakers in either door - everything will be fine... I suppose the L3 and M3 wires are connectet to the SAME contacts at the existing speakers...

Yeah both wired up the same so far for the front. Haven't done the rear yet.
So the positive/negative really make no difference as long as it's all the same for each speaker? There's no phase control on my head unit and I don't have an amp. Not don't car sound system before, but home cinema I'm all over!

A bit late with this I know but there's a very simple way to determine speaker polarity.
Use a small battery, anything from AA to 9v smoke detector type. Attach wires to both speaker terminals. Hold one of the wires to the negative batt terminal and touch the other wire to the pos terminal briefly. If the diaphragm moves towards you (to the inside of the car) then you have correct polarity. If it moves away from you then flip the battery connections. It's easy to trace the polarity through the factory connector to determine which colours Nissan was using that day. |

I too have the same question as i see it wasnt answered fully - so here goes - does anyone actually know what SM and/or SL are as far as negative and positive polaritys are in wiring the aftermarket speakers in the front doors as the pioneer speakers are clearly indentified the nissan is not clear and sound is so important to get right
