Hi, I own a 2014 Toyota Avalon, which I use as my daily driver. Over the past summer, I encountered a problem where one of the car's dash speakers slowly stopped working. After researching, I found that the car has three dash speakers, one on the driver's side, one on the passenger side, and one on the center, connected/combined with the two side speakers. The issue appeared after my sister took a road trip over the summer, where the car came back with the center dash speaker obviously blown. There was a clear buzzing sound coming from the center speaker, but the main issue arose later on when I realized that from time to time, the driver's side dash speaker started to cut out for long periods. For the last month or so, this cutting out has been pretty much permanent, where the speaker now rarely kicks in after very long drives, but it hasn't happened for the last week. I'm pretty sure that the driver's side is not blown since when it rarely works, it works wonderfully, but the problem is getting it to work. I have also checked the car's fuse box to see if there were blown fuses that could have caused this issue, but all the fuses related to infotainment were in good condition.
Lately, this broken part has been bothering me a lot, to the point where my ear has been hurting while driving. I wanted to know if anyone here knew what this problem could be and how I could solve it on time since the car cannot be in service for long periods of time because of its role as my daily driver for college.
Thank you for your help
Well I would assume your sister just blasted the speakers too high and blew them. They are made of paper after all and then she could have ripped them so that sometimes they work now and sometimes they don't. That's generally what happens
As Scotty says the speakers are most likely blown. The solution is to replace them.
Another possibility would be damage to the amplifier but as far as I know the only way to tell would be to test it with speakers that are known to be good.
Assuming the car has rear speakers that are working properly and a front-to-back fader control for the audio, a workaround might be to turn down the front speakers completely and just use the rears. (I do this in my '99 Cherokee because the front speakers are bad and I'm too lazy to replace them.)
