BMW E46 Owners with DSP systems and no HU

**edrock200** · 10-13-2004, 09:31 AM

How did you wire it? I've been told by a few that it will be a pain in the *** to use any existing equipment because of the custom speaker and amp wiring...most suggest replacing all speakers, running new wire, and buying an amp.

I'd like to eventually replace my HU with a carputer but before I do so I want to make sure theres not an easier way to use the existing speakers...anyone have a wiring schematic or information on this?

TIA,
-Ed

for 2002+ cars you could use the OEM auxilary input, but that won't help you...

I would ask this question to the audio experts at e46fanatics.com

edrock, did you find this answer? I am in the middle of my project on a 2004 330i and have not started the audio side yet. I want to hear the sound quality with my carpc first before I tear out all OEM sound. Let me know if you find somthing and I will let you know as well.

2003 E46 here

I did not replace my stock headunit, but I can tell you that you're probably better off just mounting the screen to where the sunglass/ashtray area is. Unless you want to replace every audio component in your car it's probably better to just use AUX IN on the stock headunit. BTW the sound quality on mine is pretty good. Sounds just as good as the business CD player quality.
