I'm a proud owner of two Mazda's, both have been trouble free but the 3's
front right speaker in door and tweeter on dash has stopped working.
The back right speaker does work. My first step will be to test the speaker in the door with an ohm meter - and replace it if needed.
I'm hoping the problem is with a connector common to both of the speakers.
My car does not have the Bose system.
Does anyone know where the audio power amp is located in a 2014 3 touring sedan?
Thank You!

 

Have you tested the speaker yet?
Have you swapped the front speakers side to side to confirm if it the speaker at fault?

 

I did pull the dash corner cover off to find that there is no speaker there just a blank cover where the speaker should be. So now that I've learned that my car only has 4 speakers I will buy two new front door speakers and maybe the back door speakers later on. I'm still deciding if I want to buy component speakers and run wires to the dash for the tweeters or just get a good pair of coax speakers which would be easier to install.
