Pinout - Factory Amp HK system E46

Hi all - I did a ton of searching through forums and Google trying to find a good representation of the wiring of all the speakers coming out of the factory amp. This is beneficial to anyone modifying their system - so they don't have to run speaker wires all over the place.... or try to test which speaker is which with a battery.

Below you will see a list of all speakers, locations, color, and +,- coming out of the factory amp.

Hope this helps someone else.

(Verified with AllData 10.4 and a few sites on the web I found.)

First attachment is just the speaker wires.

Awesome, would you have the rest of the wire and pin designations for the amp? Head unit inputs, sub connections? Having all of them would be extremely useful.

So I cut off the plug that would plug into the factory woofers (Factory woofers have been long gone) so that I could tidy up the underside of the deck area for my Dynamat job that was supposed to ensue later this day. In doing so, I've now blown a fuse and my radio wont turn on. I'm on the way to the hardware store to get some more fuses. But can anyone think of a reason why it would do this? Could it have occurred from the ground an power touching with the wire cutters? I'm hoping I don't have to do any wire tracing.

My Ride: e46 M3
Harmon Kardon Signal Question

I am new to the e46 M3 so forgive me if this is a dumb question. I have been crawling through the forums trying to understad the difference between the Harmon Kardon Business CD system and the regular Business CD head unit. the wiring seems to be quite similar, so I have a question. Are the signal wires from the head unit to the Amplifier line level or speaker level?

The reason I ask is that I am trying to install a Parrot MKi9200 and since Parrot only offers 2 channel line level or 4 chanel speaker level I am trying to find the bext way to integrate.

If the signal from the head unit to the HK amp is speaker level then the integration is easy.

I wanted to chime in and second that the m3 convertible does not match these pinouts. I just finished up my install tonight and was using these diagrams as helpful references though.

I should add that the colors in tenchomermoz's diagram do match, at least the woofers anyway, to the colors in the cabrio, although they are not in the spots the diagram lists.

Also an interesting thing I discovered; the rear stock woofers, at least on my '02 m3 cab, are out of phase with the fronts. I was checking my new front woofers with a Known polarity (AA battery) and I happened to check one of the rear woofers for no reason and when you put Batt+ to the + of the new woofers they move forward, and when you do the same to the stock front woofers they do the same. But if you put Batt+ to what is labeled + (and the wire coloring matches standard bmw brown for ground) on the rear woofers, they move inward. Very odd. I though out of phase was no good.

The head unit puts out what is called a "balanced differential" signal. Not many aftermarket stuff supports this kind of signal yet. I don't know if it's a strong enough signal for a LoC to do anything with.

A few years ago people used the VEN4 by Pheripal (spelling?..), which from what I can understand is a Line out converter. The question is why everyone used this unit, and since itīs no longer in production, which should we use now? What are the specs to look for?
