2004 Ford explorer speaker trouble

[Chason Ziino]

Hi All


I have a 2004 explorer eddie bauer with stock mach audio system. As you know there is no aux input on the stock radio so I attempted to put in my own aftermarket radio. Struggled quite a bit. Radio illuminates and works fine now but during course of installation lost sound from front right speaker and back left.


I took everything out and put the stock back in with same problems. Hoping for some advice about figuring out what happened. When I cross the the + and - for the speakers there isn't any pop or crackle which makes me think fuse might be out somewhere.


Thoughts?

HI There,
Welcome to the forum.

So you only lost sounds from the front right and rear left. That's a little odd.
I would double check the connections on the speakers themselves.

Did the factory system have an amp?
