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.

There is mode called "PWR-IC OFF". If you set this mode in the CD player then the internal amplifier will shut off. But internal pre-amplifier will remain on. Then you can connect the same speaker outputs to an external amplifier.
But it may not be possible to shut off internal amplifier for the front only. Either you can shut off for all OR for none. There is no way to shut off half because there is only one power IC for all the outputs.
