This is because your unit goes in to protection mode because of some bad connection in the input/output section .Disconnect your spkrs,inputs..turn the volume is Down all the way and power it up,Check your wiring for shorts at the inputs and outputs.
i had this same problem yesterday. what you have to do is 1) check all your fuses, 2) check your ground\ power 3) you might have to wire your power wire to your steering console (thats what i had to do)
