Speakers Cutting out Intermittently

[19Zen]

My car has recently developed an issue where the N/S/F speaker will intermittently slightly click/pop when I switch the stereo on and then none of the speakers will work. I’ve since replaced the speakers and head unit as they were well overdue, yet the fault still happens so it must be related to wiring/connectors. The speakers occasionally cut out and come back on when going over bumps and have tried a wiggle test at the speaker and head unit end but nothing seems to help diagnose where the fault is. I've checked all the fuses and they're all good.

I can’t find anything similar with a resolution having a search around the forums and was wondering if anyone has any recommendations on fault finding for this issue? Thanks in advance for any tips...

It appears this was due to the wires for the factory tweeters (which were removed years ago) touching each other after recently replacing the tweeter covers, some electrical tape and it's all working now.
