2003 non-dsp amplifier pinouts

[pvoltti]

Some articles claim that the 2003 non-dsp amp has 26 pin output connector and the others say that there's 12 pins. So...is there 26 pins or 12?

Good question.... I'd like to know the answer to that as well....

Yep... that's the "best quess" I have. However, it seems that you can't get subwoofer output from that connector. Any idea what is the best way to get sub-out signal? (And is the signal line-level or speker level?)

One thing to remember... A non-dsp sound is a little wide definition since the system varies from market to market.

In NA there are two sound systems:
- Basic business system
- Premium with DSP.

In NA even the basic business system has an external amplifier in the trunk rear left corner.

In EU there actually are four different systems / combinations available:
- very basic system BMW CD (no external amp)
- BMW Business CD (no external amp??)
- Hi-Fi speaker system (external amp, same as US basic version)
- Hi-Fi Professional system (DSP amp)

I haven't added a sub to my NA X3 yet but I did add a sub in my Finnish spec E46 with Business CD (no external amp). I just grabed a speaker level signal from the rear speaker wire (see one pic where the blue/brown twisted wire can be seen crossing the trunk and fed that into the amp. I did use an amp that was able to receive differential high level signal (just in case I needed in the future). Never had a single problem. The amp also turned on itself based on the speaker signal so no remote turn on signal was needed.

Attached a few pics for fun. I came up with a removable subframe and removable take away if needed subwoofer. The latter was basically to enable easy access to spare tire if needed.

Boy, that sure is a different vehicle in the EU.
