I just went through and installed a Kenwood Deck in my 2006 Jeep Liberty. After installation the drivers side speakers stopped working. I then reinstalled the stock radio to make sure they didn't go out and they worked just fine. I know i have the amps on my speakers, I was just curious if anyone knew what the hell was going on and could give me some insight. I am currently working with Crutchfeild Tech Support as well.
