I've got an 03 Sonata GLS that had the cd/tape deck double din radio. I am having a problem with the sound now. I took out the factory stereo and replaced it with a simple Kenwood head unit (KDC-HD548U). It powers up and works in iself, but for some reason i have no sound what so eer coming out of the speakers.

Every site I have found for a wiring diagram has produced different color wires for the speakers and all of them are differet from what my sereo has.

Can anyone shine some light on this problem for me? I hope its just something stupid that I missed.
