what is meant by "car audio"? an amplifier will not turn on if it is missing either ground, 12v or 12v accessory turn on. the respective wire colors will be large red wire for 12v battery source, large black wire for -12v ground battery or chassis, thin blue wire for accessory 12v turn on. these wires can be tested for 12v with a multi-meter or a simple test light.
a car radio is basically the same wire design for power up, most radios will need 12v to the yellow wire, accessory 12v for the red wire and chassis ground for the black. test these wires the same way the amplifier is tested and repair any wires not functioning correctly.
if this does not help, respond with more detailed accurate assessments of problem for further advise.
Have you checked the fuse?
I'm not sure if it is the amp. My zx2 has 236055 miles on it and my amp still works. If I were you i'd check the fuse, (i'm sure you've tried that already) but that was my problem when i had my car rewired my audio fuse was blown. Good luck.
the audio fuse is located under the hood, it is blue and is the first one from right to left and the top one. hoped i solved ur problem.
First, remove the bulbs. Second, replace the fuse. If the fuse still blows it's a wiring problem. The fuse is doing it's job by not allowing the short to burn up the car.

there should be a fuse for the audio system in the car fusing panel, but if for the speakers only- then that should be within the audio system itself.
