What kind of car did you install this in? Did it have a factory radio in it? If I had to take a guess I would think that there is a factory amp that you may have hooked the blue wire from the alpine deck to. If this is the case when you switch to CD the alpine deck turns off the power to the power antenna lead(blue wire) and thus your factory amp. If this is the case hook the factory amp turn on to the blue and white wire and you should be good to go.

SOURCE: How to wire a stereo system
Connect the 2 gage to the battery thru at least s 50 amp fuse, then connect the capacitor in line before the amps. Then run the 2 gage to a connector/splitter block and run 4 gage leads to each amp. You also will need at least 4 gage ground leads from each amp to a body grounded bolt or screw. You need to run a quality set of speaker leads from the head unit to the amps. The speakers will need separate leads from the amp to each speaker.You will need to try some different combinations to get the sound and bass you want. You want to be able to fade from front to rear and control everything thru the head unit.
Use a hole saw to cut a 2 to 3 inch diameter hole in the side of the speaker box for a port to get a better punch from the sub.
Hope this helps some....

You need to run the RCA cables from the head unit to the sub for the audio signal, and possibly a turn on wire (the blue one on the back of the head unit), unless the sub has an automatic power feature.
The sub also needs power and ground wires attached, but those do not connect to the head unit. Power should be run directly from the battery with an inline fuse, and ground should go to the nearest good ground point (Trunk latch, seat bolt, etc).
