Hi,
I'm new to the site.
I've been having a audio trouble with my 2007 ram 1500 sport quad cab.
I' m not sure what radio is in it,been only one month I've owned it.
The problems are

1- left speaker is not working. When I try the speaker on the right side it works,and right speaker doesn't work on left....so speakers both work
- checked wires in door,one was broken,spliced it,I hear a hum from the speaker,but no music.

2- when I tried to isolate the rear speaker I found that the fade and balance seem to be messed up...example,I fade to the rear on the radio,the speakers in the right side work,I fade to the front,leftside(only the front speaker of course)


Anything you could give me as info would be great.

Thanks
