Audio Systems: audio system, electric antenna, infinity sound

Question
i have a 200o chrysler 300m and i installed a new radio and new speakers and the radio works but no sound will come out of the speakers when the a cd is installed in the cd player or when the my ipod is hooked up. what am i doing wrong? it has the factory infinity sound system

Answer
you connect the wrong blue wire from the new radio, there are 2 blue and blue w/ white stripe
switch them and everything will work
the problem is that you are turning the infinity amplifier with the electric antenna output,
that output turns on am FM only
