996 + Pioneer= No sound from rear
 

Just upgraded my 2001 996. It has door speakers, dash speakers, and rear speakers. I used the 2 wiring harnesses from Crutchfield.com and everything turned on and work fine EXCEPT the door and rear speakers. The doors are silent, and the rears sound like mumbled garbage. I upgraded to the Pioneer 4400HD. WHAT DID I DO?!
