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!

Alright, I tested the leads directly from the car. The blue pair. I received no reading on any setting on the multimeter lol. The car was on and everything was as it should be. Curious, I hooked up my previous, crappy aftermarket radio and it worked just like before (has a built-in amp). At any rate, I kept testing all the connections as I connected them. Plugged in the amp, and tested the outgoing plug and received some minor readings. Plugged in the stereo again and it made its cycle sounds, but still nothing. There does seem to be power getting to everything.

If the amp was bad, would the stereo still react like it does when plugged in? Is there anything I need to change electrically to accommodate the amp?
