Hi guys, I wanted to know if the stock contour CD players exist with a built in amplifier and not only those that need the external amplifier nehind the glove box..I am about to get a player from a CEG fellow and I want to make sure I can use it in my AMPlifier free contour...he told me both models exist...with and without the built in amplifier..I really thought they were all designed to have the external amp. please let me know ASAP
