Radio Works, CD Doesn't

[mattbookpro]

I have looked and looked and can't find the answer to this one. Any help would be great.

I just barely (like an hour ago) installed Sony CDX-GT210 in my 98 Dodge Ram. The radio sounded good so I put everything back together. Then I put in a CD. Only the rear speakers play.

When I switch between CD and Tuner mode I can hear the player do a "click" much like when I select different speaker sources on a standard receiver. It's like it switches from 'A' to 'B' where 'B' is the rear speakers only.

Thanks in advance.

I am guessing that your truck has a factory amp and you used the wrong wire to turn the amp on. Sounds like you used the power antenna wire instead of the amp remote wire.

Ah, yes. Here's the really stupid thing about the Sony CDX-GT110 and CDX-GT210. They do not have a true remote turn-on wire; only a power antenna lead. (They also do not have any pre-outs). Your Ram is probably equipped with an Infinity audio system, which means there are factory amps that must be activated to hear the sound.

I'm assuming you used a wire harness for the installation. What you need to do is disconnect the blue wire in the harness from the blue wire coming from the Sony head unit. Then take the blue wire coming from the wire harness and connect it to the red wire in the other plug. When you're done, the blue wire from the Sony head unit will be connected to nothing; the red wire from the Sony head unit will be connected to the red wire in the harness AND the blue wire in the harness. This will activate your factory amplifiers when you turn the key on.

Alternately, get rid of the Sony head unit and upgrade to a model with a true remote output. You should definitely do this if you intend to add any kind of amplifiers to the system.
