You should start with the fuses.

ya, possibly the amps fuse is blown, other than that your deck may have just decided to stop sending signals

if it is factory amplified make sure that you have hooked up the remote turn on wire from the deck to the amp.

I am going to have to go with Kenmci on this, im guessing the remote turn on for the factory amp wasnt hooked up.

It is Factory, do you really think that the manufacturer didn't hook this wire up?

locate the factory amp, and test the wires with a light bulb tester when the radio is off. There should be one power wire. Then test it with the radio on, there then should be 6 powerd up wires.

See what happends there.
