Problem with stereo/ speakers, help please!

[tugg]

Okay so I hooked up all the lines to the new radio to the car and no sound comes out at all. I set it up based on

Constant 12V+: Red/Black
Switched 12V+: Blue
Ground: Chassis
Illumination: Red/Blue
Dimmer: Red/Yellow
Antenna Trigger: Black/Red
Antenna Left Rear

Front Speakers 4" x 6" Doors
Left Front (+): Blue/White
Left Front (-): Blue/Yellow
Right Front (+): Brown
Right Front (-): Brown/White

Rear Speakers 6 1/2" Rear Deck
Left Rear (+): Red
Left Rear (-): Green
Right Rear (+): Blue
Right Rear (-): Pink


and no sound comes out of the speakers at all, but the radio deck is getting power to it, the switch and constant. My car previously didn't have a radio when i got it, so what could be the problem(i dont think it would be the speakers blown out, because at least 1 of the speakers would work or at least give some noise)?
