No Constant power in new stereo

Hello all, I'm really hoping someone can help me out and possibly give me some instruction to fix this problem. I recently installed a new CD Player in my car, everything is connected as it should be,(I bought the wiring kit), the CD player works great however I have no constant power, therefore my presets don't work as well as my clock. Does anyone have any suggestions or has run into this problem before??

The oem radio has two main power wires. one is for clock/preset/memory functions and is orange. the other is ignition controlled and is yellow. Check to see if you have power at the orange wire. if not, check the fuse.
