location of amp

[workexpo]

hey guys new here. my 03 expedition right speakers all don't work, from the front to the rear. very staticky and popping. the left speakers work fine, i just have to balance the audio all the way to the left. i was thinking there might be something wrong with the amp. however i am unable to find it. can you guys show me where it is?

Try holding keys 3 and 6 while in radio mode. That does a diagnostic test on all the speakers for the 2000+ headunits, though not sure if it'll do it for the 03?

Either way, I think it's in the drivers side rear panel, but don't quote me on that.
