Re: Leaf Speakers Replacements

I am a little confused regarding the color coding for rears
Randys post states

Rear Left (+) Violet / Grey
Rear Left (-) Light Green / Grey

Rear Right (+) Light Green / Grey
Rear Right (-) Pink / Grey



Any pointers on which one for the 2012

left Rear
Red
Green

Right Rear
Purple
Green

Thanks

Just look at the stock speaker, IIRC positive is on the right if looking from the side with the cone facing up. Doesn't matter what colors as long as you are consistent here.

If you were to change only the fronts, you'll need to match the existing wiring polarity on the rears. I forgot where I saw it, but there has been at least one incorrect post of polarity - use a 1.5v battery connected to the speaker to check, the cone moves out the front of the speaker for positive polarity.

See the photos in my posts for matching Infinity polarity to the stock speakers (felt tip pen marks I added) - all four factory speakers are the same.

Yes the polarity is opposite to Phil s post from the front of the speaker IIRC positive is on the left

Phil was correct, negative is on left from front of all factory speakers. The incorrect polarity was shown on another thread.

The left neg did not sound right I had no bass is there a way to check the polarity coming from the head unit with a volt meter.
Do we know the +/- color codes for the rear on a 2012?

If you get the polarity reversed on one speaker, and correct on the other, you will see greatly diminished bass. To check, simply use the balance/fader to select one speaker at a time and listen to music with a lot of low bass. If the bass gets louder with one speaker selected, you have polarity problems.

There is no easy way to meter the polarity from the head unit. Simply look at the OEM connectors and figure it out as described above.

I thought a multi meter that can read milliamps may help, excuse my lack of knowledge here but the signal must have a value?

Guess I just have to pull the doors (again)

I'm still not sure why all this guessing is necessary? :? If you solder every speaker the same, using the same plug/connector configuration as stock, how can the polarity be wrong? Surely Nissan wouldn't wire them wrong.
