Answer
It sounds like cross wiring of some kind. I think you will have to pull the units and bench test them to make sure they are working correctly, then recheck the wiring very carefully and make certain you know exactly where all the wires are going.  There is no room for a mistake, as you have learned.

To bench test, pull the head unit and the amp out; hook them up outside the car. If you do not have a 12v supply, use long wires to power up the units from the car battery.  Connect a known good speaker directly to one of the audio output channels on the amp.  Check it out with a cd running in the head unit. Then, check each amplifier one by one.

When you have satisfied yourself the cd player and amps are all working properly outside the car you can turn your attention the car wiring.  If it is an older car you can usually find something that will help on www.installdr.com or one of the other sites.

Also, you can purchase wiring harnass and adapter kits from crutchfield.com for the exact car and model you are installing to.

Hope this will get you going in the right direction.
