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 !
