noticed recently that the driver side front door speaker is much quieter than the left. I’ve checked the speaker balance settings in the sound menu, and it’s definitely set up to be 'central' sound. Before I start messing around trying to get to the speaker to check connections, has anyone got any tips for what to check first, or how to get to the speaker, or any other bits worth checking?

thanks

Advice from an ex tv and audio engineer State Service Manager Pioneer Electronics WA in the early 1980's...
Listen closely with your ear to the speaker and play an audio clip with speech in it or tune to a radio station with speech. If the speaker has "poled" it will sound distorted. "Poled" means the voice coil is rubbing on the central cylinder of the magnet assembly causing the distortion.
Another possibility is the right front channel amplifier has developed a fault. The two faults should be easily distinguished by an experienced audio engineer, but not perhaps by a layman.
It is extremely unlikely to be a wiring fault.
The first thing to do would be to get hold of another speaker of the correct impedence and substitute. Most car sound speakers have 40ohms impedence, but Nissan could have put anything in there.... You could swap the left and right door speakers to ascertain, but that entails stripping down both doors-a bit of a pain. My advice if you are not particularly handy yourself would be to take it to a local car sound specialist for diagnosis.
If you don't mind getting down and dirty you can save yourself a pile of money by swapping out the left and right ones.

Good luck.

thanks, I appreciate your detailed advice. I'll see how it goes, should be able to cope with the things you've suggested!

Interesting, our 2017 Tekna very occasionally has same problem. It comes and goes, so have never tried to fix it.
First noticed it last year, about 2 days after the 3yr wty ended, typical !

well its taken me a while, but I’ve got a bit further with this. I found this video which was really helpful for getting the door panels off.

then I swapped over one of the rear speakers into the driver door. It made a big difference and was back to normal again. I looked over the faulty speaker and there was nothing visually wrong with it, so I wonder what it could be? Was hoping I’d be able to repair it - will have to do a bit more digging. That or find someone with a door speaker going spare. Not sure I’m that bothered really to upgrade the speakers to anything else.

hope the update might help someone else. Would be interested to know if anyone knows how to test the dodgy speaker and figure out if it can be saved.

Quite hard to fix a speaker that looks OK. The problem is likely inside the voicecoil/magnet assembly i.e. the bit in the centre. Maybe @Barfly can advise further but I'd say it's a goner.

A speaker that size and quality isn't expensive, say £10 to £30, very approximately. A local scrapyard or eBay may provide.

Good luck!

Kind regards

@JDleaf Garry is correct, it would not be economic to get such a speaker re-coned, although there are specialist speaker people who can do the job. I would suggest looking on-line Amazon/ebay/aliexpress and get a new one, secondhand or crashed vehicle ones from a scrap yard may have other issues, the doors and windows on the Leaf are not exactly waterproof!!!
If you hold the speaker close to your good ear and gently move the cone in and out you will probably hear a scraping sound. You should not be able to hear that!

Just look on the back of the speaker for it's impedance, this is critical. It should be a standard 4 Ohms, but knowing Nissan it could be anything, I have seen some weird and wonderful values in some cars even 120ohms on an Aussie Ford derivative.
If there is nothing on the speaker, don't bother trying to measure the dc resistance, speaker impedance is an ac measurement at a nominated frequency, usually measured around the 1000hz frequency. You will have to dig into the parts manual, I have a link for them in my dropbox account here: https://www.dropbox.com/sh/kdrmel9bo4vpox7/AAAzZFJnW_iO_EBoa9cAc96Oa?dl=0

You will also have to ensure the replacement is physically able to fit the cut-out in the door panel. There are a zillion different sizes.

Thanks so much both, really helpful. I’ll have a look over the speaker for the impedance, and the see what I can get my hands on in terms of a replacement. Not too much of an issue just having the duff one in the back for now!
