Stock Stereo Won't Power On, (CD/Tape Combo Player with Amp) Options

[MegaMac]

Alright, guys. I have a problem.

I have an original Toyota stereo as seen here: http://i00.i.aliimg.com/img/pb/987/270/614/614270987_491.jpg

Since that particular system requires an amplifier, I purchased a stock one from a member on here, identical to the one seen here: http://i.ebayimg.com/00/s/MTIwMFgxNjAw/z/y...Q/$_57.JPG

All cables are present and all connections fit and are tight. No missing prongs or severed wires. Once everything was ready to go I turned the car on and I heard the laser cycle, but the player did not turn on. I pressed the power button, and nothing. I also did the button combination to unlock Toyota radios, but it was still unresponsive. What am I doing wrong? Did I miss something? All fuses that relate to the radio and dash are fine as well. It seems to be getting power, but man, I am at a loss.

Any help on this would be greatly appreciated!

Yeah, the moment you unplug the stereo, the stereo locks itself as part of the anti-theft system. Although if you indeed have the same stereo as in the OP, it doesn't check with any BCM or VIN, you would just have to input a sequence of button presses on the stereo to unlock it, which only the dealer will provide. The sequence varies based on the stereo ID number located next to the Toyota logo on the front of the stereo.
