Aftermarket headunit No Sound - Help!

[blackhat840]

Hey guys,

I am pretty new to the forums. I've searched through the forums as well as google and I have followed a few instructions on getting this to work but it has not worked. What I am running into is this. My display on my radio quit working but you could use the buttons to change the stations and use the business cd but couldnt see anything. So I decided to go with a aftermarket head unit. I went and I purchased a headunit, dash kit, and a metra antenna adapter and wiring harness from metra.

However, I got everything hooked up and the radio comes on, but no sound comes out of my speakers. I've pulled the fuses for 72 and 73 for 5-10 minutes, I've unhooked the amp that is on the left side of the boot and hooked it back up but still not any sound. Does anyone have any suggestions? Its like the amp is not getting powered on or something to produce the power for the speakers. Am I missing a power wire for the built in amp? Any suggestions would be greatly appreciated!
