I have installed a new radio unit, but I have a very unusual problem....

Seems that the CD output is WAY lower than the Radio output. If I switch between the two, the Radio seems to be amplified and the CD out is not. I am using the RCA outputs on the new stereo.

Its almost as if the build in car amp turns on, but only amplifies the Radio output. I cannot figure out what I am doing wrong, or if the radio just has a really bad amplifier for the CD portion.

I would appreciate any help you may have. Anyone else have this issue?
