Wire colors for factory stereo output

[shomatt]

Does anyone know which wires are factory low level outputs on the factory JBL system stereo. I'd like to put in a new head unit but keep the original amps since the sub runs off the main amp. I have a wiring diagram, but it deosn't list what wires/colors are what polarity and channel.

Thanks for anyone's help.

I know of a plug that will help retain your factory amps. It also sends a low level signal to them. Its made by American International. To describe what it looks like .... There are RCA's at one end that goes to the aftermarket radio. The other end plugs into the factory wiring harness that sends the signal to the JBL amps. If you are interested and want more info send me a E-mail ...

Do you need the colors by the amp in the trunk or in the dash behind the head unit?
