speaker problems

[importune]

I recently baught a '95 chrysler lhs and installed this deck(kenwood KDC-MP828) from my old car. This deck has been great for me in the past. When I play the radio in this new car the audio is perfect, love it. My subwoofer and my stock speakers work. But, heres the problem. When I try to play a cd or try to play audio files from my iPod(kenwood ipod interface) I only get sound from my subwoofers. My stock [COLOR=#009900 ! important][COLOR=#009900 ! important]speakers[/color][/color] make no noise at all, and i can't figure out why. :\ Any help on this would be greatly apprieciated.
