stereo wiring
 

Hello my son just purchased a bmw 2005 x3 and he is trying to install a line converter so he can add another sub (just what he needs) can anyone help

Thanks

as stated above he is looking for speaker wire color coding for the rear speakers for a line converter

Check otu the Online WDS link above. That has the wiring diagrams availabe for the X3.

With the X5 audio system, you can not easily add a line converter if you have the DSP option. I am not familiar with the X3 audio systems, but it could have some of the same technicial limitations as the X5 systems. Therefore, I would research the line and speaker output options on the X3 based on the different audio system options. Other members might have specific X3 experience.
