I unplugged the stock amp and plugged it back and now the stereo does not power up at all. I don't think it is the amp because the head unit (stock) has not power at all when you push to power it up. Checked the fuses and still look good. Please advise.

There is not a fuse on the inside of the stock headunit. I would recommend metering the power wires going into the unit to be 100% sure that the headunit was getting the proper voltage.
