It's a 98 Civic EX. I'm not getting anything from the right from speaker. I checked with a voltmeter and it says 6.0+ so it seems to be getting power all the way up to the speaker but still no sound. Both reds work just fine and I wired the two Browns. Everything else works fine but this one speaker and I also made sure the settings on the head unit were all to center and all speakers. Anyone have an idea of what it could be? Starting to guess the negative cables are bad somewhere. I've traced them all and found nothing wrong though. 😶

 

Replace it, along with the other door speaker.

 

Take the speaker out of the driver door and plug it in on the passenger side. If it works then it's the speaker itself that went bad. If it doesn't then you have an issue either in the wiring(less likely) or the channel on the radio is going/gone bad(more likely).

Also, take that multi-meter, set it to ohms/continuity, and check the speaker to see how close it is to 4ohms.(Assuming you have stock speakers or a common aftermarket)+/- .5 ohm is about the range you should be in if the speaker itself is still "good".
