The other three channels work fine.

 

stock or aftermarket stereo?

 

Stock honda stereo 200w

 

I'm having the same issue with my front right channel. I was hoping it was just the speaker so I bought a new pair of speakers and it's not the speaker, it's something electrical I think. Were you ever able to solve the issue?

 

Duolicate thread, just different sub-forum: https://www.fitfreak.net/forums/fit-diy-repair-maintenance/82911-front-left-channel-stereo-failure.html#post1271508

 

did you guys do something simple, like check for continuity between radio plug and speaer plug? might be a break i wire

 

Equally simple... fader and balance are both centered?

 

I know how to use fader and balance controls. Look in the duplicate forum for more.

 

It was the door harness.
