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,

Oops, posted in wrong forum. Mods, please move to newbie.

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

Thanks, I'll check it out over there.

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.

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.

I just realized I'm thinking about this all wrong...I now have a new plan.

I'm not real senesative to audio quality, most systems sound good to me, and adding a sub to any system seems be a good touch. I like my HK system and the only reason I would replace it would be to integrate the screen in the dash (which would require removal of the HU to fit the screen.)

Well I don't know why I didn't think of this before but I can easily move my HU into the glove box, which would allow me to keep my steering wheel controls, radio and CD player, speakers and existing HK setup, and still integrate the screen into my dash. I already purchased an aux adapter and installed it so that'll be my sound input (you can buy aux adapters for pre 2k2 cars also.)

Since I'll really only be using the HU for the aux input and radio I'll won't need access to it since I have radio and volume controls on my steering wheel.

If my motherboard EVER arrives from mini-itx (going on 2 weeks now) I'll start to post pictures.

edrock200: Relocating your head unit to your glovebox sounds like a great idea. One thing you may not have considered: I don't think it is possible to switch sources (cd/aux/phone/radio) via the steering wheel controls. The switching function is only possible via the head unit buttons. So this would require opening your glovebox to switch sources. Another possible problem: is the glovebox deep enough to hold the head unit? The head unit is pretty deep...

But this DOES sound like a really good idea...so much in fact that I am considering this in my ride now...it would get me back my volume control and bluetooth phone steering wheel buttons...

One more thing: will the wiring harness for the head unit be long enough to reach the glovebox?

edrock200

Yeah I was thinking about these items today as well. I really don't plan on listening to the radio very often so I would most likely just leave it in AUX mode. However, the button has to be a simple contact switch and I could probably wire an external switches, on for the CD button and one for the FM button. I don't use Phone (will be using bluetooth) and the aux works with the CD button in my car. If I could rig up a button I might even be able to hide the unit back in the dash somewhere.

Otherwise it's really not a huge deal if I have to use the glovebox to change inputs as I will rarely be doing it.

As for the wiring harnass, I also thought about that. I know they make extensions for the antenna cable but I'll have to extend the harnass manually. As long as I do it one wire at a time I should be good. I'll post to this thread on my progress for relocating the HU.
