Factory Wiring harness to Factory Subwoofer
 

Does anyone have a wiring diagram of the factory wiring harness that connects to the OEM Factory subwoofer for a 04 X5 4.4i w/NAV(Non-dsp) ?

If I have Navigation on the car already, do I need to get a whole new wiring harness to do a DSP upgrade?

Can someone send a pic of where the wiring and harness might be located in the rear right component. I found a wiring harness under the spare tire, but the connector doesn't seem to fit on the sub, I'm not sure if thats the connector. Any help would be appreciated. Thanks

I don't think the vehicle is pre-wired for DSP with sub, but the actual wiring schematics that we use at the dealership is the "online WDS" link at the top of the page if you want to dig around for the differences. Then you could see what all is different.

Otherwise, I'm sure someone on this forum has done that upgrade (as the DSP system sounds great!) and may chime in. If so there may be a thread on it already, have you searched the site?

yea, i did some research on this site and found some members that completed this retrofit. I will PM them to see if they have more info. Thanks again, I will look at the online WDS for the wiring schematics
